A Message from Germany: Growing Disaster Preparedness favours Ham Radio

For a long time most radio amateurs in Germany found themselves in the defensive: Building regulations, combined with EMC standards, heavily restrict antenna possibilities. Neighbors fear “dangerous” radiation, often going to court without any legal reasons. Emergency services got a much improved digital communication systems (TETRA), removing many of the artificial borders where they sometimes used ham radio to build bridges.

This could be quite different, as you can see in Austria. If radio amateurs organize a congress about emergency traffic, even the federal government and the Austrian army send competent representatives.

But the political turmoil and the connected energy crisis change attitudes in quite some branches of administrations:

The county of Soest urges citizens to buy license-free PMR handheld radios so they can reach the “light houses” that the county of Soest is creating all over its area.

The county of Ebersberg, east of Munich, is well known for its initiatives. Recently they invited the regional chapter of DARC, our German ham radio society, to discuss the build-up of a resilient data net for the county. In normal times, this data net could be used as part of HAMNET, our part of 44net. The county and towns would help to get access to suitable positions, including power supply. Some of the stations, for example on town halls, might be dormant most of the time. But as soon as power goes out, local radio amateurs are to activate the emergency net. The first application is to be VoIP, i.e. a independent phone service.

The county of Freising, a few km to the north, is also interested in working together with radio amateurs. We are just building a task force for this.

These activities are quite different from traditional emergency traffic. The most important difference: We work as enablers, not as radio officers. Our task will be to maintain the system, make it operational in case of an emergency, and introduce the officials to its use.

This is critical as we do not have enough radio amateurs to get the messages, send them over our system, and hand them down to the respective officer: Multply 2 radio amateurs by 3 shifts per day by a new crew every second day by the number of sites.

And in normal times, we can enjoy a much improved HAMNET coverage. Until now, most radio amateurs only had to access 44net through VPNs over the Internet.

10 Meter Beacon DXing

by Walter Salmaniw, Masset, BC

My hobby of radio listening has evolved over the years.  Beginning with crystal radios as a child in the 60s, I’ve migrated through SWLing with numerous rigs including the kings of valve technology, like the Collins R390A and Racal RA17, and then on to high end mil-spec solid state rigs:  Racals, Harris, Ten-Tec, and my all-time favourite, the Rockwell-Collins HF-2050 receiver.   Unfortunately, broadcast band stations, especially transmitting to North America, have dwindled over the years, and my favourite Pacific stations also disappeared:  120 and 90 meter Indonesians, the 60 meter AIR network, and the numerous PNG stations.  Well, what’s one to do?

About 10 years ago, I switched over to MW DXing, and especially trans-Pacific and trans-Atlantic DX.  My cottage near Masset, BC is the ideal location for such DXing, as I have an ocean beach location, the room for some great antennas, and very low noise in the area.  This has produced some incredible DX, and I’ve been honoured with visits by some pretty eminent DXers, including Victor Goonetilleke from Sri Lanka, Mauno Ritola from Norway, Vlad Titarev from Ukraine, as well as our own experts in DXing from Victoria and the Pacific North-West of the US.

MW DXing is great, but that involves DXing primarily during the night time and early morning hours.  What to do with the rest of the day?  Well, with the rising sunspot counts and heading toward the peak of the next solar cycle, why not look at 10 meters?  About 2 years ago, with a lot of help from the local DX geniuses, I was able to remote my set-up in Masset, and DX even when at home in Victoria, BC.  10 meters has consistently remained open almost every afternoon.  Now, I’m not a ham, and at this point, have no interest in obtaining my ham license.  However, I noted a lot of beacon activity on 10 meters.

I’ve dabbled in LW NDB DX, which can be a lot of fun.  Why not do something similar on the higher frequencies?   Not being a ham, I needed some help with decoding the beacons.  Thankfully, one can often see the CW and it’s slow enough to read in many cases.  Being a bit too lazy for that exercise, though, I’ve tried several software solutions to use with my KiwiSDR and Perseus SDR in Masset.  Fldigi is probably best known, and works fairly well.  Another program I use is MixW, which I’ve always liked for SSTV reception.  Another is CW Decoder.   None, however, get anywhere close to how well CW Skimmer works.  It’s an awesome program, albeit a pricey one.  I’m still in the test phase, but will likely go ahead and fork over the $75 to purchase this.  It will even take control of my Perseus receiver and decode 192 kHz worth of spectrum.  Wow!

     Here’s an example of what the band looked like last weekend:

There happened to have been a world-wide CW DX competition, but nonetheless, there were literally hundreds of CW signals to be decoded!  Now, for me, however, I was more interested in the Beacon region of 10 M which is roughly between 28150 and 28300 kHz.  I’ve found CW Skimmer to be a perfect tool to decode the beacons.  Not only is it very accurate, but one can also easily see the CW signal with the dahs and dits on the screen and a continual readout of the messages.  Most of these beacons run 5 or 10 W, and all are run by amateurs.  Where to find information about who they belong to?  That’s easy as well.  WI5V.net has a great 10 M beacon list at https://wi5v.net/beacon-list-table-version/ .  That’s my go to, but I also have DL8WX.de’s beacon list on my laptop, giving even more information, like contact e-mails, etc.  He’s found at:  http://www.dl8wx.de/BAKE_KW.HTM

What type of antenna do I use?  Well, none of mine are 10 M antennas at all.  Most are, in fact, for DXing trans-oceanic MW DX!  Still, they seem to work quite well.  My go-to has been a DKAZ antenna aimed 290 degrees.  Now, that’s 180 deg to where most of my Beacon activity comes from.  How come?  Well, Nick Hall-Patch, MW DXer extraordinaire, used his ENZEC antenna prediction program to see how the DKAZ works on 28 MHz, and sure enough, it’s opposite to MW DX.  On the lower band, it’s best aimed 290 deg, but 180 deg opposite on 28 MHz!   Who would have guessed that one?  In any case, the next time I’m in Masset, I plan on putting up a simple vertical for 10 meters, seeing that solar max is still a year or two away, so there’s plenty of time for some fun DX!

Here’s what I’ve heard with a few afternoons of listening.  My best catch has been Darwin, Australia!

28207   N4XRO  1924  CW  5 watt beacon heard with a bit of a buzzy signal best deciphered on my 110 deg DKAZ….  17/Oct/2022 (Salmaniw, Masset, BC)

28236.5   W0KIZ  1933  CW  Another well heard beacon this morning giving ID in CW along with location.  Also very strong at 23:11 recheck.  Almost a barn burner!  Not bad for 5 watts! 17/Oct/2022  (Salmaniw, Masset, BC)

28244   WA6APQ  1934  CW  Much stronger, and it shows with their 30 watts output, with slow CW giving callsign, then location. Very strong when rechecking at 23:05 UTC.  Frequency is actually a little lower than listed.  Actually measuring 28243.942 kHz.  17/Oct/2022  (Salmaniw, Masset, BC)

28287   WI6J  1949  CW  Poor reception, but with same format giving ID and location.    17/Oct/2022  (Salmaniw, Masset, BC)

28250   K0HTF  2248  CW  Fairly good copy of this beacon away from the coast now in Iowa.  Only giving callsign/B.  Tom ‘Doc’ Gruis

replyed to my email confirming he’s feeding 20 Watts from an Old President radio and feeding an AR-10 antenna.  Thanks, Doc!  17/Oct/2022  (Salmaniw, Masset, BC)

28248.3   NJ5T  2258  CW  A relatively difficult catch, but I decoded the J5 part of his call, as well as ‘dipole’.   17/Oct/2022 (Salmaniw, Masset, BC)

28215   KA9SZX  1954  CW  Beacon quite well heard from Masset.  Most of my 10 meter beacon loggings have been a more N/S axis, but this one is coming in nicely in our early afternoon.  Callsign and power listed as 3 W, along with his email address. 5/Nov/2022  (Salmaniw, Masset, BC)

28218   AC0KC  2035  CW  Despite being listed as on 28218.5, he’s actually on the even channel at fair level into Masset.  Solar powered and only 3W, into a Bazooka antenna (what’s that?). Call sign repeated.  5/Nov/2022  (Salmaniw, Masset, BC)

28220   AA8HS  2123  CW  Despite listed as 30 Hz higher, I’m hearing them on the even channel with repeated IDs.  Fair level. Antenna listed is a vertical J-Pole.  5/Nov/2022  (Salmaniw, Masset, BC)

28230.3   W2MQO  2125  CW  Strong reception with call sign as W2MQ0/B repeated twice, then tones, and cycle repeats.  Into a Bazooka Antenna.  5/Nov/2022  (Salmaniw, Masset, BC)

28203   KG8C0  2132  CW  Another strong beacon with call sign, and prolonged tone, and repeat.  5/Nov/2022  (Salmaniw, Masset, BC)

28203.5   K6LL  2134  CW  Strong signal also from California, ID’ing as K6LLL/BCN, and giving location and QSL info.    5/Nov/2022 (Salmaniw, Masset, BC)

28193   VE4ARM  1827  CW  Excellent reception of my first 10 meter Canadian Beacon.  Run by the Austin, MD Amateur Radio Museum, as outlined in their beacon text.  6/Nov/2022  (Salmaniw, Masset, BC)

28284.8   N9TNY  2226  CW  Another new one for me from Illinois.  Not a particularly great afternoon, but nonetheless, a number of CW Beacons on 10 meters are visible/audible.  Callsign is given, then PSE RST.  Not sure what that means?  Wiki tells me that this is like SIO or SINPO code.  Stands for Readability-Signal Strength-Tone.  Hmm.  28/Nov/2022  (Salmaniw, Masset, BC)

28297   NS9RC  2237  CW  Another Illinois Beacon audible.  This one is weak, but fiddling with the KiwiSDR AGC settings, makes for a much better decode (mostly raising the CW Threshold (marked Thresh CW in the AGC section).  Near 100% correct decode now. Chicago is sent along with call sign.    28/Nov/2022 (Salmaniw, Masset, BC)

28287   WI6J  2240  CW  Strong signal from this Californian, and heard before.  VVV VI6J/B Bakersfield CA DM 5     28/Nov/2022 (Salmaniw, Masset, BC)

28236.5   W0KIZ  2300  CW  Always one of the strongest beacons on 10 meters, and not disappointing this afternoon.  VVV W0KIZ/B DENVER, COLORADO . 5 WATTS, So does he mean 5 or 0.5 Watts? Presumably 5 Watts.  28/Nov/2022  (Salmaniw, Masset, BC)

28206.5   KA7TXS/B  2303  CW  Nice reception with VVV DE KA7TXS/B DM22 Listed in dl8wx.de website, but not the primary one I use (wi5v.net Beacon Website).  28/Nov/2022  (Salmaniw, Masset, BC)

28232.3   W7SWL  2323  CW  I like the callsign!  Fair reception with VV DE W7SWL TUCSON AZ DM42  The band is fading fast.  Fascinating that the best antenna for 10 m Beacon reception today is my 290 deg DKAZ (and not the 110 deg DKAZ).  Not sure why! 28/Nov/2022  (Salmaniw, Masset, BC)

28206.5   N4SO  2231  CW  Very weak, but really picked up just now.  DE N4SO/B repeated. A fine catch!    30/Nov/2022  (Salmaniw, Masset, BC)

28212.8   AC7GZ  2253  CW  Very strong reception with VVV DE AC7GZ AC7GZ AC7GZ DM43BI  30/Nov/2022  (Salmaniw, Masset, BC)

28209.5   N2UHC  2300  CW  Tough copy, but bits of STPAUL decoded. as well as N2UHC/B.    30/Nov/2022  (Salmaniw, Masset, BC)

28254.5   K4JEE  2308  CW  Strong reception with ID and location.  Deep fades, as well, though.  30/Nov/2022  (Salmaniw, Masset, BC)

28255.8   WI5V  2310  CW  Fair reception with occasional good fade-ups with WI5V/B repeated.  30/Nov/2022  (Salmaniw, Masset, BC)

28175.5   VE3BKM  2034  CW  Hearing an unlisted beacon.  VE3BKM/BCN repeated, often at strong level.  A new one for me! 5/Dec/2022  (Salmaniw, Masset, BC)

28168   VA3KAH  2040  CW  I have no idea where this island is located, so had to look it up.  Fair reception with VV DE VA3DAH/B It’s located to the north of Lake Simcoe in southern Ontario. 5/Dec/2022  (Salmaniw, Masset, BC)

28145   DL2WB  2048  CW  A highly tentative logging.  All I hear is the occasional tone for several seconds, then off.  Nothing else listed on this frequency, so no idea!  5/Dec/2022  (Salmaniw, Masset, BC)

28203   KG8CO  2055  CW  Very strong signal with repeated KG8CO/BT 5/Dec/2022  (Salmaniw, Masset, BC)

28203.5   K6LLL  2058  CW  Weak reception with VVV K6LLL/BC Grid Square coordinates, and PSE QSL TNX DE K6LL/BCN.  5/Dec/2022 (Salmaniw, Masset, BC)

28206.3   KA7TXS  2100  CW  Strong reception, although a bit of a congested part of the band making decodes a tad difficult. Not listed on my main source (WI5V Beacon website), but it is on the dl8wx.de website.  5/Dec/2022  (Salmaniw, Masset, BC)

28208   WD5GLO  2126  CW  Fair copy with WD5GLO/B repeated 3 times and OK OK  5/Dec/2022  (Salmaniw, Masset, BC)

28209.1   N5TIT  2130  CW  Poor reception this afternoon, but making out the call-sign.  VVV DE N5TIT/B.  100 Hz higher than listed.    5/Dec/2022  (Salmaniw, Masset, BC)

28209.5   N2UHC  2133  CW  Poor reception, but seeing his callsign. Fades up to quite good at times.  N2UHC/B EM27JM N2UHC/B ST PAUL KS.  5/Dec/2022  (Salmaniw, Masset, BC)

28217.7   K4PAR  2152  CW  Very weak, but fully decodable with VV DE K4PAR/B.  Listed as from the Piedmont ARC and 25 W.  Just barely audible.  5/Dec/2022  (Salmaniw, Masset, BC)

28220.15   AA8HS  2155  CW  Measuring below their listed 28.2203 frequency.  Weak but in the clear.  5/Dec/2022  (Salmaniw, Masset, BC)

28232.3   W7SWL  2206  CW  Now that’s a call-sign!  He wasn’t there a few minutes ago, but noticed a very powerful beacon.  VVV DE W7SWL W7SWL TUCSON AZ DM42 and repeated.    5/Dec/2022 (Salmaniw, Masset, BC)

28254.5   K4JEE  2220  CW  Another beacon I recognize from previous sessions.  Fair to good reception this afternoon with VVV DE K4JEE/B K4JEE/B K4JEE/B LOUISVILLE, KU EM78.  5/Dec/2022 (Salmaniw, Masset, BC)

SSTV Fiesta 2022

Many thanks to SWLing Post contributor, Mario Filippi (N2HUN), who writes:

For those who’d like to try receiving SSTV images and also get into the holiday spirit, there is an annual SSTV Fiesta from December 12, 2022 to January 6, 2023. The Fiesta is sponsored by the Azteca DX’ers. The frequencies are 14.230 MHz in the 20m amateur band and 27.700 MHz, just above the US Citizen’s Band.

An excellent decoder is MMSSTV available free on line.

I’ve monitored 27.700 MHz the past week and have decoded the images below using an Airspy HF + Discovery, 31 foot ground mounted vertical, MMSSTV software and VB cable for piping the audio from the Airspy to MMSSTV.

Note that you have to set your receiver to USB. With MMSSTV you can set your receiver on the frequency of choice and just walk away like I did and the software will store any images received. Image clarity depends on propagation, just like other modes.

Good luck, thanks go out to the Azteca DX’ers for this enjoyable event and 73’s.

In search of the unique, the weird, the unusual . . . a reader participation post

By Jock Elliott, KB2GOM

There is a richness in human experience, and I want to sample it.

When I worked the world on the HF ham bands, I considered myself a “conversation hunter.” I wasn’t content to simply make a contact, exchange signal reports, and move on; I wanted to talk to people in foreign lands, to chat with folks who did unusual things, to hear things you would not normally hear otherwise.

Here’s a quick sampling:

  • I spoke with a ham in England, a falconer, who flew the birds for the movie “Lady Hawke,” and who had a side business of manufacturing tiny transmitters that falconers could use to track their birds.
  • The chief groundskeeper for a major university in Ohio once explained, on ten meters, the difference between commercial and consumer lawn mower engines (the commercial units are designed to be rebuilt quickly and easily).
  • Recently, on 2 meters I heard a ham explain how he used VHF/UHF crossband repeat to provide coverage for a special event.

Similarly, I enjoy hearing the unusual on the AM, FM, or shortwave broadcast bands. For example, one evening years ago, on shortwave I heard “Radio Peace and Love” from somewhere in the Caribbean, followed (on another frequency) by “Mark from Michigan” extolling the militia movement. On another occasion, I heard a story on Radio New Zealand about a Maori weaver’s collective.

So, bottom line, I am interested in the unique, the unusual, the weird (could be all three!) . . . and I prefer stuff that is NOT syndicated across a bunch of stations. Marion’s Attic comes to mind as I write this.

So, now it’s your turn: what’s your favorite programming that is off the beaten path? Please respond, and be sure to mention the time and frequency when it might be heard.

Tom’s Recommendations: Earbuds and EQ Settings for Shortwave Listening

Many thanks to SWLing Post contributor, TomL, who shares the following guest post:


Earbuds for Shortwave Listening

by TomL

A few years ago I had bought the discontinued Sennheiser MM 50 earbuds for a cheap price on Amazon to use in my various radios.  The portable radios in particular can use more fidelity because of their small, raspy speakers.  I also like to listen without bothering others around me who might not want to listen.  And earbuds are a LOT more comfortable for my ear lobes than any over-the-ear headphones I have ever used.  Furthermore, the old Apple iPhone 4 earbuds were very harsh to listen to.  However, a trade-off is that, generally, earbuds are somewhat fragile; one of the two pairs of MM50’s died through mishandling.

I was generally happy with them while listening to Shortwave broadcasters with a mix of news/talk and music.  I especially liked them on Mediumwave listening; stations can sound surprisingly good when playing music.  Then I tried using these earbuds on my Amateur Radio transceiver, a Kenwood TS-590S.  I was impressed how clear they sounded with a lack of distortion, although there was too much bass.  Fortunately, Kenwood supplies USB connected software with an TX & RX 18 band EQ (300 Hz spacing, not octaves).

Here is a frequency response chart I found from Reviewed.com for this model:

One of the notable things about these earbuds is the total lack of distortion.  Most likely one of the reasons they sound so clear on Shortwave, which has many LOUD audio spikes.

I had not wanted to get Bluetooth earbuds.  However, I had recently upgraded my cell phone and NO headphone jacks anymore!  So, while I do not use Bluetooth yet for radios, I can see a time in the future to get a Bluetooth transmitter to plug into a radio with a headphone jack.  I am reluctant since I do not like having to recharge my earbuds and I put in a lot of radio listening time.  Am I supposed to buy two Bluetooth earbuds and swap while charging?  Maybe in the future.  And also, am I supposed to buy a Bluetooth transmitter for every non-Bluetooth radio I own?  Not likely gonna happen.

In the meantime, I ordered cheap wired earbuds from Amazon.  I had a $5 credit for trying Prime, so when I saw these Panasonic ErgoFit wired earbuds (RP-HJE120-K) for slightly over $10, I said to myself, “why not?”.   Supposedly wildly popular, they are one of the most rated products on all of Amazon with 133,821 ratings/opinions (perhaps Russian bots?!?!?).

Here is a frequency response chart from ThePhonograph.com for these Panasonic earbuds:

You can see comparatively that the bass response in the very good Sennheiser MM50’s is much stronger, being good music earbuds.  But for voice articulation, not as much, even though they have no distortion.  The Panasonic ErgoFit’s have more modest bass, less of a dip in the lower midrange audio frequencies, and more importantly, has a peak near 2500 Hz and its harmonic 5000 Hz.  The highest highs are also modest compared to the Sennheiser model.  This general frequency response to “recess” the bass and treble frequencies and peak the 2500 Hz is very useful for voice intelligibility.

As described by the famous speaker-microphone-sound-system maker, Bob Heil relates what he learned from the scientists at Bell Labs many years ago.  Speech intelligibility is enhanced when audio is compensated for our natural human hearing.  Equalizing below 160 Hz, reducing the 600-900 Hz region, and peaking the 2000-3000 region centered at 2500 Hz will increase intelligibility dramatically.  The story goes that Bell Labs was tasked by parent AT&T with finding out why the earliest phones in the 1920’s sounded so muffled and hard to understand.  After many experiments, the scientists found the most important frequencies for our ears + brain to comprehend speech.  In other words, our ears are not “EQ-flat” like a scientific instrument is.

Checking out the new C.Crane CC Skywave SSB 2

By Jock Elliott, KB2GOM

Folks who are regular readers of my posts here have already figured out that I am a big fan of the CCrane Skywave SSB. It is easily the most versatile radio I own, receiving AM (medium wave), FM, shortwave, HF single sideband, NOAA weather stations with alert, and scannable civilian VHF frequencies, and I have written enthusiastically about it here on multiple occasions.

I think of the Skywave SSB as my “anti-boredom machine.” It’s small enough to slide into a shirt or jacket pocket pocket or tuck into any pack. Get stuck waiting in line, whip out the Skywave SSB, plug in a pair of ear buds, and listen to whatever is available.

So when I noticed that a new version of the Skywave SSB – the Skywave SSB 2 – appeared on the first page of the C.Crane 2023 catalog, I was delighted that the folks at C.Crane decided to send one to me. The SSB 2 includes all the goodies of the original, plus a handful of incremental improvements; upgrades include a micro-USB port for external power or charging NiMH batteries, a slightly better speaker, and longer feet on the bottom for better stability.

But the improvement that really makes me grin is a two-fer: first, the inclusion of an external antenna socket on the side of the SSB 2, and, second, the CC Wire Terminal Antenna Adaptor for shortwave, which is a 2-wire to mono plug adaptor that plugs right into the external antenna socket. This allows a long wire antenna to be easily hooked up to the SSB 2, and it works like crazy.

Attaching a long wire to the SSB 2 is now really easy. Attach your long wire to the CC Wire Terminal Antenna Adaptor (you’ll need a small gauge screwdriver; the screws are really small). Next, plug the adaptor into the external antenna socket. You’re done!

I attached a 45-foot end-fed antenna to the CC Wire Terminal Antenna Adaptor while listening to some hams chatting on 80-meters and found that it delivered an impressive improvement to the signal-to-noise ratio. And when I wanting to hit the road, it was a simple of unplugging the adaptor so the adaptor and wire antenna combo would be waiting when I came back.

The SSB 2 includes a number of useful accessories: the CC Wire Terminal Antenna Adaptor, a portable 23-foot CC Shortwave Reel antenna, CC Ear Buds (very comfortable), and a faux leather carrying case (if packing the SSB 2 in your luggage,  be sure to press the LOCK button, otherwise you find yourself with a singing suitcase or backpack.).

Bottom line: with the introduction of the Skywave SSB 2, CCrane has taken an excellent, versatile radio and make it even better. Highly recommended for all-round use, but especially as a travel and/or emergency radio.

Note: Jessica from CCrane sent me the following note regarding the SSB 2.

Please note:  When using headphones or earbuds there is an easily discernable, but not loud “pop” when switching bands and on memory presets on airband. There is no pop when using the speakers. It will take time to find the hardware and software remedy. It will not be corrected on this first shipment but we are working it and expect it to be reduced on future shipments. The new Skywave SSB-2 was up for a price rise October 2022 but we’re keeping it at $169.99 for now.

Some select Black Friday Deals for 2022

[Note: This info. is also posted on our sister site, QRPer.com.]

The very affordable, tiny, and retro Raddy RF750 is on sale for $34.39. We have never tested it, but it receives mostly positive reviews.

I’ve been trying to avoid looking at sales this week because I don’t really need anything. That said, I’ve had a few pieces of gear on my mind that I’ve been wanting to review/evaluate and Black Friday has made a few of them more accessible.

Nanuk Waterproof Cases

If you’re not familiar with Nanuk, they produce a wide variety of waterproof cases in Canada. They’re essentially Canada’s version of the Pelican case.

I’ve been eyeing their Nanuk 903 which is actually a very compact case–something similar in size to the Pelican 1060 and the Evergreen 56.

Nanuk, DX Engineering, and Amazon all have their Nanuk cases on sale today. I picked up a Nanuk 903 that I hope to use with one of my ultra-compact field radios (perhaps the Penntek TR-35).

Prices vary, but Amazon seems to have the lowest. I just purchased a blue Nanuk 903 with pick foam for $28.00 shipped (affiliate link). Other colors may cost a few dollars more, but they’re all exceptional deals (I picked the least expensive color).

CP Gear Tactical

I believe it was Rod (VA3ON) who first introduced me to this Canada-based pack manufacturer.

I’ve had their their Aircrew/Pubs Bag with Padded Tablet Pocket on my wish list since the Ham Radio Workbench podcast episode where we talked about backpacks and pouches. CP Gear Tactical manufactures a wide variety of gear primarily for the Canadian military market. Everything is made either in Canada (NB) or the US (or both), thus prices are much higher than mass produced gear.

I’m hoping their Aircrew bag might fit my 2nd Yaesu FT-817ND which is now outfitted with the TPA-817 pack frame I purchased from a reader.  If it doesn’t, I still have many other uses in mind.

Everything in their store is 20% off today if you use the coupon code BKFRIDAY20.

The pack, shipped to my address in the US was $92.60 CAD.

Yaesu FT-891

I noticed that Gigaparts and Ham Radio Outlet has the venerable Yaesu FT-891 on sale for $599.95 US. That’s a brilliant deal.

Last year, I came so close to buying the FT-891 for $629 during a Black Friday sale. I decided against it at the last moment because I know I tend to reach for my lightweight QRP field radios that can provide me a few hours of radio fun on a 3Ah battery. Even at QRP output levels, the FT-891 needs a larger capacity battery.

That said, if you’re looking for a new 100W radio for the shack or field? The FT-891 is a solid choice. The ‘891 is also an excellent general coverage radio for shortwave radio listening.

Radioddity

Radioddity always has deep discounts on Black Friday. This year, they have a store-wide 15% off sale with a coupon code.

Radioddity is a great place to purchase Xiegu Products. They are a sponsor of QRPer.com.

SDRplay RSPdx

SDRplay manufactures affordable, high-performance SDR receivers in the UK. They are currently offering their RSPdx for £130/€156/$169.95. Click here for details and click here for my review of the RSPdx. The RSPdx is a choice radio for mediumwave and low band work. That said, the frequency range is exceptionally wide. This and the RSPduo are my favorites from SDRplay. Note that SDRplay is a sponsor of the SWLing Post.

Airspy

Another SDR and radio accessory manufacturer, Airspy, is offering 20% off of all of their products. I consider their HF+ Discovery SDR to be one of the best sub-$200 SDRs for the HF bands–check out these posts and reviews on the SWLing Post.

Amazon portable radio deals

I noticed that Amazon.com does have a wide variety of shortwave portables in their Black Friday sale. Click here to search through the ones listed in the Black Friday promotion (affiliate link).

Ham radio retailers with Black Friday deals

Here’s a list of ham radio retailers who have Black Friday sales today. If you’ve been looking for an item in particular, you might compare prices between these stores:
