Dear Thomas and Friends,

Giuseppe Morlè (IZ0GZW) here from Formia, central Italy.

This my latest video is about everything I have done to protect and transport my Icom IC-705.

I bought an aluminum case, light and very resistant with everything one needs inside to be able to use the IC-705.

    • 2 power banks, one of which is solar-charged to be able to recharge the battery while in operation
    • 2 wire antennas: a dipole type with BNC / banana socket with 10 meters of cable per arm and a 20 meter row, monopole, to be used in reception as you saw during the DXpedition to the Island of Ponza
    • I also bought the Mydel protective “cage” with antenna attachment on the front and PVC protection of the display

Given the high cost of this little jewel, it is advisable to take all precautions for its safety during transport and use.

I hope I made you happy …
Thank you all,
73. Giuseppe Morlè iz0gzw.

This is great, Giuseppe! Like you, I’ve taken extra measures to protect my Icom IC-705 as well. Your kit looks comprehensive–I love the fact that pretty much everything you need is inside. 

Thank you again. We always enjoy your posts from beautiful Italy. Ciao!

Report from Ponza Island: May 6-9, 2022

by Giuseppe Morlè (IZ0GZW)

Ciao Thomas and Friends at the SWLing Post!

This is the summary of 3 days of testing of my Icom IC-705 just purchased and immediately taken to Ponza Island, my hometown, for a full immersion DXpedition only listening to amateur radio bands especially on 20 m.

Day 1

I left Formia on the ship that went to Ponza and it was not a good start given the adverse sea weather conditions. After 3 hours of crossing in the rain and the strong sirocco wind, I arrived on the island at my father’s house.

In the early afternoon in the rain, I hoisted a 20 meter row on the “sloper” type roof not so high from the ground and connected directly to the Icom 705 without any counterweight given the place without electrical noise.

The position of my father’s house is open from West to North but totally covered to the South by a hill of 200 meters …

In this video you can see all of this:

During the first night, 20 meters was full of signals especially from the USA; it was, in fact, what I had hoped for given the position open to the West.

Really good overseas signals despite bad weather … below is a series of mixes of North American stations: Continue reading

The Icom IC-705: Giuseppe’s pairs his new radio with his homebrew crossloop antenna

Many thanks to SWLing Post contributor, Giuseppe Morlè (IZ0GZW), who shares the following:

Dear Thomas,

I wanted to share my new purchase with all SWLing Post friends: the Icom IC-705.

It is truly a great portable QRP transceiver and a great receiver for broadcast listening.

In this video, shot on my balcony at home, is the first listening test on short waves. Crystal clear audio with cathedral effect. My portable cross loop antenna pairs very well with the IC-705.

It’s a simple video but it brings out all the listening potential of this 705.

Greetings to you and all the friends of our community.

73,

Thank you for sharing this, Giuseppe! I’ve found that the IC-705 has become one of my favorite portable receivers. It’s truly an amazing radio and, I believe, worth the hefty price tag. 

I published a very favorable review of this radio and 13DKA has as well. Also, check out Giuseppe Fisoni’s comparison of the IC-705 and IC-R8600. The IC-705 is a proper enthusiast-grade radio–I would purchase it just for the receiver functionality. Being a ham radio operator, I also take the IC-705 to the field very regularly–I post many of my field reports on QRPer.com. Recently, we’ve posted a number of articles about protecting the IC-705 during travels and in the field.

Thank you again for sharing this, Giuseppe!

Uli asks: “How well does the Icom IC-705 receiver work on longwave?”

Many thanks to SWLing Post contributor, Uli (DB1ULI), who writes:

Hello Thomas,

I started to enjoy BCL and SWL some week ago (again). I have a HAM license for many years, but was QRT for the past few years. Now, the HAM bug bit somehow again and I’ve been listening to the bands via a Tecsun H-501 but changed this one to a Reuter Pocket already.

The Reuter Pocket (Source: Reuter)

The Pocket is a really great receiver including also the FM Bands and the popular (in Europe) Digital Broadcasting DAB.

Still, it is just a receiver. So for now I am searching for a new rig, too. The current offerings are all tempting, FT-DX 10, FT-991A, IC-7300, IC-705 and so on. I really like the new models due to their features, and most due to their displays. My former rig was a Yaesu FT-897.

I already read your and the other reviews of the IC-705 (especially the BC receiving parts) and it could replace the Reuter in many ways. I am just a little bit reluctant because I like the longwave band a lot (we still have stations here) and there is no info to find anywhere how it works below 500kHz. MW seems to be on par with most other receivers.

Do you have an idea about a source of information concerning the capabilities of the IC-705 below 500kHz?

All the best and 73,
Uli

Great question, Uli. I’m hoping that some of our European IC-705 owners may be able to help you here. Although I’ve spent a lot of time on mediumwave with the IC-705, I’ve done little exploring of longwave. 

Please comment if you have thoughts on the IC-705’s longwave performance!

Looking back: What radios did you use the most in 2021?

I’m not sure why, but near the end of the year I always like to look back at my radio routine and figure out which radios I used the most. Often, the answer is surprising.

This year, I realized there was a very clear winner…

The C.Crane CCRadio3

The C.Crane CCRadio3 has taken lead position as my daily driver. I have it turned on most days for as much as 4-5 hours at a time depending on how much I’m at home.

Here’s why it has become my daily driver:

  • Benchmark AM/FM reception: The CCRadio3 grabs a solid lock on my favorite local and regional MW and FM stations. At the end of the day, my favorite news program (Marketplace) is available on a local WCQS and distant WFAE. The CCRadio3 can lock onto both equally well. I’ve very few portables that can do this. In addition, I use the CCradio3 for casual MW DXing when I’m not using the Panny RF-2200 or my Chuck Rippel-restored SRII.
  • Audio: The audio from its internal speaker is superb for voice content, but also robust enough for music. I love the dedicated Treble/Bass controls. The audio can be turned up to the point that it can be enjoyed throughout our house.
  • Bluetooth: I listen to a lot of content online and pipe it via Bluetooth from various devices to the CCRadio3. I stream the CBC, FranceInfo, ABC, and/or the BBC most mornings from my laptop. I use Radio Garden on my iPad to explore a world of local radio. I also stream Apple Music from my Mac Mini to the CCRadio3. When I do workouts on my stationary bike, I’ll often listen to both podcasts and music on the CCRadio3 via my iPhone.
  • Battery life: The battery life on the CCRadio 3 is simply stellar. It takes four D cells which offer up a lot of capacity. There are so few digital display radios today that can quite literally play for a few months on one set of batteries. I invested in a set of EBL D Cells and Charger (this package–affiliate link) and have been super pleased. When in the shack/office, the CCRadio3 is plugged into mains power via the supplied AC adapter. All other times, it runs on rechargeable battery power.

It’s ironic, too, because the CCRadio3 doesn’t cover shortwave which is, without a doubt, my favorite band. Thing is, now that so many of my staple news sources are difficult to reliably get on shortwave in the mornings (oh how I miss Radio Australia) I turn to FM and online sources for news content. I still listen to the BBCWS, RNZ, RRI, and at least a dozen other news programs on shortwave, but due to my schedule, it’s mostly casual listening.

On the go: The Belka-DX

Speaking of shortwave, though, the portable I’ve used the most this year for SWLing has been the Belka-DX. Besides it being a super-performing DX machine, it’s also incredibly compact and portable. I keep it in a small Tom Bihn zippered pouch and it lives in my EDC bag which accompanies me on all errands and travels.

The Belka-DX is so small, I forget it’s there. Even some of my smallest compact portables are nearly three times the size of the Belka-DX.

In the field: The Icom IC-705

If you follow QRPer.com, you’ll no doubt see that I spend a lot of time in the field doing QRP amateur radio activations of summits and parks. As I’ve pointed out in my review and 13DKA has pointed out in his reviews, the IC-705 is a benchmark shortwave, mediumwave and FM DXing machine. At $1300 US it’s pricey for sure, but it offers up a usable spectrum display/waterfall, audio RX controls, customizable filtering, HF/VHF/UHF coverage, and built-in audio recording/playback.

You don’t even need a 13.8V power supply with the IC-705 as it’ll charge from most any USB source via a Micro USB plug and run in receive for at least 5 hours without needing a recharge. Of course, you could invest in a second, higher-capacity battery pack and get even more battery life.

When I take the IC-705 on a field activation, I’ll often do a little listening after I finish the ham radio portion of my outing. It’s a great reminder of how important it is to take your radios to the field these days. With no QRM, it’s amazing what you can receive.

How about you?

In search of benchmark signals: The International Beacon Project

by 13dka

If you – like yours truly – like to tinker with antennas and radios to get the most out of them, you likely have your own set of reference stations. If this is a new concept for you – reference stations are whatever stations you deem apt to check propagation, the general function of your radio, when trying to improve reception or comparing radios… They are ideally always on when you need them and come in various strengths and distances on several bands from all over the world. Traditional sources for that are of course time signals and VOLMET stations on HF, even though the latter are giving you only two 5-minute slots per hour for testing reception from a specific region and the former have their own specialities here in Europe:

A typical scene on 10 MHz, captured at home 30 minutes after the full hour: BPM voice ID from China mixed with something else, then Italcable Italy kicks in on top of some faint murmur possibly from Ft. Collins, in winter some South American time stations may stack up on that together with splatter from RWM 4 kHz lower…

A reliable source of grassroots weak signals is particularly desirable for me because I enjoy proving and comparing the practical performance of radios at “the dike”, a QRM-free place on the German North Sea coast. In the absence of manmade noise and the presence of an ocean adding 10dB of antenna gain, finding benchmark stations with “grassroots” signal levels turned out to be a different challenge than it used to be: With somewhat sizeable antennas the stations tend to be (too) loud there, even with the baseline ionospheric conditions under a spotless sun in its activity minimum. In short, my old benchmark stations didn’t work so well anymore and I had to find something new. Continue reading

Guest Post: Dikeside Icom IC-705 RX action

Many thanks to SWLing Post contributor, 13dka, who shares the following guest post:


The IC-705 in action at the dike

by 13dka

When I got the IC-705 in late October 2020, I didn’t get that much chance to enjoy it at the dike: After a couple of initial tests and 2 nightly “FYBO” MW DX sessions in November, a way too long and wet winter struck the German North Sea coast, with nighttime temperatures recovering to 2-digit Celsius figures only in the past few weeks. I took the opportunity to do more experiments with loops, preamps and a phasing unit to improve the RFI-stricken reception at home, so I could at least listen to European hams on 80 and 40m raving about their new 705s and start to write my own musings about that lovely little radio, recently posted here.

SSB DX

June 1st, 202

Finally, acceptable temperatures at night! But they come with a downside: When I connected the vertical around 8:00pm (local time), it was still almost 2 hours before sunset and a lot of thunderstorms in Europe made even 14 MHz very noisy, my hopes for some nice catches were immediately taking a dive. A short scan of the bands brought up nothing special, the only notable thing being the CB and 10m bands being moderately open. I should’ve known better: As soon as the sun splashed into the ocean, grayline propagation worked its magic!

Grayline while receiving Japan, June 1st

As the image probably hints, a couple of Japanese “big guns” produced some nice, comfy signals on the monopole, in addition to the South American and Carribbean stations usually booming in here!

Video: A short collection of ham stations heard around midnight

After midnight I noticed a residue signal of WWV on 20 MHz and still a few EU beacons on 10m. Both incredibly weak with QSB making them disappear but that’s where the 705 really shines – it’s not only picking up these grassroots signals just fine, it shows me that they’re there, or that they were there – a waterfall display keeps on proving that a perceived lack of activity on a band is often pure bad luck – you can tune across an entire band without hearing anything because on each frequency with some activity there’s the other (inaudible to you) station speaking right now, QSB is dipping the signal just when you tune past it…

June 5/6, 2021

That evening the Japanese stations were missing on 20m, I thought I picked one up on 17m, and like so often, the one odd Australian station came in on 20m. After midnight I noticed the 10m beacons again, there were even a few more of them. This time I brought my Belka DSP to the dike so I could compare it with the IC-705, after all the Belka proved to be my most sensitive portable before! The devastating result is likely owed to the fact that the Belka is pretty picky about passive antennas not being matched very well to its input (which is much optimized for the whip) but it picked up diddly squat. If it isn’t a testimony for the sensitivity of the IC-705, it might be one for its aptitude to cope with all sorts of antennas.

Then I tuned into the 10m SSB range and I was veeeery surprised to hear VO1FOG from St. Johns, Canada! This is the first time I heard a transatlantic signal on 10m in a solar minimum ever, but it was with condx only elevated enough for some daytime DX within the EU…and literally in the middle of the night! The signal was very unstable though, he later switched to the 12m band which worked better. Back to what I said about the waterfall display above: Without it, I could’ve missed this station with a pretty high probability simply because I didn’t expect any activity up there, so I wouldn’t have tuned across that band for very long, and without seeing the signal while the VFO is already somewhere else…

I also heard another new country (Ecuador) in SSB, the usual collection of Carribbean islands and some participants of the “Museum Ships Weekend Event” including NI6IW, which is the vanity call of the history-charged USS Midway in San Diego. The “Japanese” station JW4GUA turned out to be on Svalbard island, with the main town Longyearbyen being the northernmost town in the world, only 650 miles from the north pole, and I don’t hear stations from there very often!

Video: June 5th

June 10/11

The past days saw the SFI passing 80 and 11/10m becoming quite busy. By the time I parked the car at the dike, SFI had dropped to 73. That evening the grayline confined itself to colorizing the horizon. 10m and 11m were still full of signals, I could still hear 2 British chaps chatting on 27 MHz at 3:00 in the morning, but nothing really “extraordinary” was coming in – the one odd VK, more Carribbean islands, one Argentinian but not much from other parts of South America, it never gets boring how this all defies predictability. But as always I heard most of the North American continent, not booming in much that night but I followed 2 POTA activations for a while, which are usually at most 100W stations working a lot of other “barefoot” stations and I heard almost all of them. In the morning grayline window for the west coast I finally got one solid signal from Oregon. All my radio life, the US west coast has been a tough target for some reason.

The signal had that typical “over the pole” sound, a relatively quick phasing imprinted into the signal by the charged particles converging over the pole, causing northern lights in the region and that exiting feeling when observing really big, planetary scale physics in realtime, over here at my listening post. The magic of shortwave. 🙂

Broadcast bands

After the post touting the IC-705 as a SWL/BCL receiver, demonstrating it on the broadcast bands seems mandatory to me. However, capturing cool BC DX is a very different business than waiting on the ham bands for interesting stations coming and going and collecting spectacular (-ish) results in a single night this way. Broadcast schedules have to be studied, current “hardcore” DX targets identified… and I have to admit that I’m out of that loop currently. Just turning the knob and recording whatever is populating the bands, and doing that between 21-22:00 UTC, when all programs are directed towards anywhere except Europe turned out to yield pretty boring results. Here it goes anyway:

Video: Browsing the most important BC bands

CONDX and antenna:

The antenna I was using in these videos was a simple wire running up a 10m/33′ fiberglass pole, forming a very archetypical “monopole” or “Marconi” antenna, just a vertical wire, no counterpoise, no matching network, no un-un, transformer or flux capacitor. I planned on using this to make some experiments about the practical benefits (for reception) of all the components it’s now lacking, but it already demonstrates that the beauty of receive-only antennas is that they often don’t require crazy efforts: On the conductive soil at the dike it works pretty well (good signals all over the bands and sufficiently low takeoff angle) as it is.

The evening and the 2 full nights at the dike once again had condx that nobody would phone home about:

SFI, A and 3-hourly K-indices while I was at the dike.

It’s not that these numbers always fully explain actual and current condx but decreasing SFI and rising A/K-indices mean low expectations. Despite the condx still characterized by the solar minimum that way, the location is always delivering proper DX for my radios. Unless stormy or severely unsettled geomagnetic conditions give DX a day off, there’s almost always something to take home, be it a new country, a rare island, unexpectedly loud signals from the other end of the planet at unusual times and/or on unusual bands or other ionospheric mysteries.

Speaking of location: These videos demonstrate the properties of that listening post as much as the capability of the IC-705 to harvest them, and they don’t put that into relation to other radios, so you have to rely on my word on this: Compared to what I brought to that place so far it’s jaw-droppingly good, but a big contributor to that is that only few of my other radios can really cope with the antennas I like to use out there in first place. A radio like the IC-705 is sure making the most out of location and antenna, but it’s not the key component because a low-noise location is everything, it always was and it is today more than ever. Without it, radios and antennas can’t really play their jokers.
