Luke considers the Panasonic RF-9000 an investment and solid performer

In response to our post about a Panasonic RF-9000 being offered on eBay for $20,000(!), SWLing Post reader, Luke, comments:

I actually just bought a RF-9000 from a Spanish Ebay seller. It might show up in the ‘completed auctions’, not sure. I made an offer of 2,000 Euros and he accepted. Of course I am like most of you who might have seen one in a magazine or book for over 20 years, but never dreamed of actually owning one.

My unit had a few imperfections like a couple of dings and the grille was not 100% with some slight discoloration but I cleaned it up nicely and got some Testors paint to fill in the dings. It came with the cover but with no documentation. Everything works perfectly and there are no dirty or inoperable switches or buttons. Even the lights all work which is a relief.

I can only really compare it to the Sony ICF-2010 and the Satellit 700, both of which I have owned at one time. I still have the Sony. The Panasonic is on a much different level as far as ease of use. And the tuning is super fast with absolutely no audio lag between channels if that is the right description. It is really smooth sailing all the way across the dial and you can go straight from FM into the LW band which is pretty cool.

Another nice feature is the band selection buttons actually have the corresponding frequencies also so there is no guesswork. The odd thing about the unit is that all of those cool buttons that you see pertain mainly to the clock and timer functions.

The shortwave side is fairly stripped down with just a 3-way bandwidth selector, a switch for a noise blanker, a RF gain knob, and a 4 position switch for USB, LSB, etc. That is pretty much it for tuning and knob twiddling and I would had preferred to have a few more knobs for antenna trim and other features to eek out faint signals. I guess I was expecting more I don’t know?

I personally find it to be the best radio I have ever used as far as audio and ease of use. I did some side by side tests against the ICF-2010 for sensitivity and it is about a wash. But for 1/10 the price the Sony wins all day long and you cant beat the sync detector! I find myself amazed that I would ever own a RF-9000 and consider it a great investment. I think this seller is dreaming if he thinks he can get that price for it though.

Thanks for sharing your review of the RF-9000! You certainly have a rare and classy receiver that actually performs–a keeper for sure. If I recall correctly, even the tuning knob feels perfectly weighted on the ‘9000.

Based on what these sell for, I don’t think you overpaid for your ‘9000–indeed, you got it at a bit of a discount.

CountyComm: A note of caution about the high-gain ferrite bar antenna

12 Replies

After our post this morning regarding the high-gain ferrite bar antenna (available via eBay), I received a message from Nick at CountyComm.

Nick notes:

“[The high-gain antenna is] very cool however we wanted to let you know that we found out it [can] actually destroy the antenna input to the GP5/SSB or GP5/DSP because of its heavy weight. [W]e had at least five radios come back [after] customers had purchased the large ferrite antenna from an eBay seller.”

Many thanks, Nick, for the feedback. It is important to note that the high-gain bar antenna is not an OEM product, so CountyComm isn’t responsible if it harms the radio’s antenna jack.

While still relatively lightweight, the high-gain bar antenna is substantially heavier and longer than the GP5’s supplied MW antenna.

I’ve been concerned about dropping the GP5/SSB with the larger bar antenna inserted–fearing the jack could break off–so I’ve been very careful using it. I’ll probably continue using the larger ferrite bar, understanding that I’ll have to handle it with care.

If you’re concerned about damaging your radio, I would suggest using an inductively coupled AN200 loop antenna instead.

Again, Nick, thanks for the heads-up!

Steven is impressed with the CountyComm GP5/SSB and high-gain bar antenna

Many thanks to SWLing Post contributor, Steven Crawford, who sent the following message to me (several weeks ago) and has kindly allowed me to share it here. Steven writes:

I hope this finds you and yours well. I just wanted to take a few moments and express my sincere thanks to you for your posts of 12/20/2014 and 1/6/2016, and for sharing Larry Thompson’s post of 2/28/2016, and Ron’s post of 1/16/2016. If you are in regular contact with the other individuals please feel free to pass along my thanks as each of you and the respective post convinced me to purchase a CountyComm GP5/SSB and Ebay seller playloudfm’s high-gain ferrite bar antenna. I am so glad I did, so a hearty Thank You to each of you.

The afternoon of March 19th local was the first chance I had to use my GP-5/SSB. After popping in three fresh AA’s on AM using the internal ferrite bar antenna Beaumont, Texas’ own powerhouse 5,000 watt KLVI 560 was there as was 1,000 watt Orange’s KOGT 1600, 23 miles away and my AM daytime benchmark 50 kW KTRH 740 Houston 70 or so miles away on the back side of their pattern. KTRH surprisingly can be a little difficult during the day due to noise. The surprise was 50 kW WWL New Orleans 240 miles away was intelligible above the background noise. Extending the whip a quickie SW test showed WWV Fort Collins time signal was present at 15 MHz.

On the AM side the real money lay after dark once the sun had set in Beaumont and San Antonio. Using only the internal ferrite bar antenna all of the aforementioned AM stations were present. Continuing the internal antenna’s test 50 kW WBAP 820 Dallas 244 miles away and 50kW WOAI 1200 San Antonio 266 miles away were present. I started grinning when 50 kW WLAC 1510 Nashville 598 miles away and 50kW KMOX 1120 St. Louis 632 miles away were just intelligible above the background noise. Keep in mind these stations were received using only the internal antenna.

I popped the CountyComm included factory external ferrite bar on and used it 9 -10 PM Saturday local, 0200 – 0300 March 20 UTC. Using the external antenna rotated for best reception WLAC and KMOX improved to the point they were easily listenable. 50 kW WSB 750 Atlanta 625 miles away was listenable above the noise and most surprising 50kW WBBM 780 Chicago 892 miles away(!!!) was just intelligible above the background noise. Another quickie SW test was performed at 10 PM local, 0300 March 20 Sunday UTC by extending the built in whip and the WWV Fort Collins time signals were present at 5 and 10 MHz with 10MHz being particularly well received.

A real treat lay in store after receiving Ebay seller playloudfm’s aftermarket high-gain ferrite bar antenna, the subject of your 1/6/2016 and Ron’s 1/16/2016 post, yesterday. I am not experienced enough to judge what the space weather or propagation conditions were like from 0300 to 0400 March 27th UTC but I was extremely surprised and pleased with the reception results the new antenna afforded.

As I sat relaxing in my easy chair before bed I decided to try the combo out using the included earphones so as to not wake my wife. With the lights off and my iPad open to www.oldradio.com/archives/stations/ccs.htm to help identify clear channel stations I took the handheld combo for a spin. All of the stations found with the factory supplied external ferrite bar antenna were present. There was just so much more signal present using the aftermarket antenna each became easily listenable. For WOAI, WWL, WLAC and KMOX the effect was as if I was located within their local night coverage area. 50 kW WHAS Louisville Kentucky 740 miles away was newly found present. Chicago’s WBBM was there as before and I was surprised to find 50 kW WGN 720 Chicago as well. The reception quality was such that one could enjoy listening to a Cub’s game or breaking local news story should one be so inclined on WBBM or WGN. The listening experience was similar for newly found 50 kW XEROK 800 Ciudad Juarez 738 miles away.

The most surprising and gratifying, to me anyway, find of the night using playloudfm’s antenna was receiving 5,000 watt (nights!) KCMO 710 Kansas City Missouri 624 miles away. The ability to rotate the antenna to take advantage of it’s directional and nulling ability really aided in this reception. It really is a great benefit to be able to rotate the GP-5/SSB’s external AM antennas for peak signal strength while nulling interfering signals and noise. Indeed KCMO was missing in one antenna orientation but rotating the antenna 90 degrees and the station popped in. I really should have jotted signal strength to noise ratios down but I was just enjoying tuning through the spectrum too much. I have not fully tested SSB Exalted Carrier tuning on the GP5/SSB of difficult stations but have tried it 3 or 4 times and it does appear to work as does tuning 1 kHZ either side of the nominal frequency. The later technique did help clean up some signals by further reducing background noise without greatly affecting listenability.

As best I can tell I ordered and received either the last or next to last of playloudfm’s current batch of high-gain ferrite bar antennas as the Ebay add showed two available when I ordered and the ad was almost immediately replaced with an “accepting pre-orders” ad. Currently there are no ads by seller playloudfm.[Note: it appears more inventory has been added to eBay.] My transaction and shipping was quick and smooth. The bulk of the two week wait occurred after the package was received at the Athens airport where tracking stopped. It should be noted by buyers should more antennas become available the tracking number supplied does not work on the USPS tracking service but it will track the package to Athens through Greece’s Hellenic Post tracking service at http://www.elta.gr/en-us/personal/tracktrace.aspx

Note: all distances listed above are “as the crow flies”, straight line city center to city center and are not necessarily correct for the transmission tower location.

This little radio is fast becoming a hand holdable favorite with easy to learn button placement for use in the dark. I am all ready beginning to prefer it to my Sony SW7600GR / AN200 loop combo for MW broadcast AM reception but I really must do more work with SW before calling the CountyComm my favorite of the two.

Steven followed up a week or so later with this addendum to his review:

I finally got the opportunity to test the FM performance of the radio using only the extended whip on the afternoon of April 1st, April 1st 19:30 – 21:00 UTC. Using www.radio-locator.com and my zip code I found 51 FM stations listed as local, distant and possible fringe reception. I was very surprised and pleased when I was able to log all of the most distant fringe stations, KUHF, KKBQ, KTBZ, KKHH, KHMX, KBXX, KODA, KILT, KLOL, KMJQ, KRBE, KOVE, and KGLK, with ERP’s listed as 90 to 100 kW and distances in the given in the 80 to 90 mile range. In short I was able to log all 51 listed stations. The FM broadcast band is crowded indeed with this little rocket radio. It should be noted my little corner of Southeast Texas is dead flat with nothing between me and these stations broadcast towers but Houston skyscrapers, the typical urban / suburban sprawl, timber and marsh. Ground elevations range from 16 ft to 80 ft above sea level between me and many of the broadcast towers.

[…]My Sony SW7600GR / AN200 loop / Sony AN-LP1 loop combination sits in it’s go bag rapidly falling into disfavor, replaced by the easily used in the dark one handed CountyComm GP-5/SSB. Again thank you for your kind response and thanks again to all who motivated me to purchase this rig.

Steven, thank you so much for taking the time to share your experience with the GP5-SSB and the high-gain ferrite bar antenna.

I also have the high-gain ferrite bar antenna and have been meaning to post videos showing how it performs compared with the supplied GP5 antenna. I must say, it does do a pretty amazing job. I’ll get some videos posted in the coming weeks!

Netherlands clears way for licensed low power mediumwave/AM stations

9 Replies

SWLing Post readers might recall that the Netherlands was considering opening licensed mediumwave broadcasting to low-power stations–it appears the path is now clear. Yesterday, Minister Kamp gave the green light to low-power stations (those with a power output from 1 to 100 watts) who can now apply for a broadcasting license.

Stig Hartvig Nielsen posted the following on the WRTH Facebook page:

Today Dutch minister Kamp has made it public that the Medium Wave band now will be open for low power stations operating with a power of max. 100 Watt. Full story here (in Dutch): http://radio.nl/…/groen-licht-voor-laagvermogen-uitzendinge…

One of the first stations to go on the air under the new legislation may be the long time pirate – Atlantis Radio 1521 – in Friesland. They got a license (?) from Commissariaat voor de Media in March 2016, and they recently purchased a new 75 W AM transmitter (300 W PEP). The format is golden oldies – and the station can be heard online here:http://www.atlantisradio.eu/radio/ – and more details can be found here:https://www.facebook.com/RadioAtlantis1521KHz/

It will be interesting to see how this decision plays out and how many stations will apply for a license. I’ll certainly listen for new stations on the U Twente Web SDR as they pop up.

BBC Predicts Internet-Only Radio in the Future

22 Replies

(The following is part news / part editorial)

According to a report going to Parliament for the BBC’s broadcast charter proposal, the BBC is preparing for an Internet-only world for broadcasting. This has prompted an investigation of other radio broadcasting services by Radio World magazine to get their take on this perspective. Part of the article “Is Broadcast Radio Doomed” follows:

Conventional radio and television broadcasting are doomed, eventually. Or so one might reasonably assume from reading “British, Bold, Creative,” the BBC’s broadcast charter proposal for the next decade of its mandate. The BBC’s 10-year broadcast charter is up for renewal in 2016. The proposal is the Beeb’s funding pitch to Parliament.

To be sure, the BBC didn’t use the word doomed, or put a timetable on it. However, over the next 10 years, “We will be moving to an Internet-fit BBC, to be ready for an Internet-only world whenever it comes,” states the BBC proposal. The only limiting factor will be to “move at the pace of our audiences”; ensuring that older subscribers have access to content on radio and TV as long as they need it.

Subsequent to issuing this proposal, the BBC announced that it is reorganizing its internal divisions along content rather than platform lines. For instance, “Each overarching division would have subsidiary divisions such as BBC Youth, a mooted subdivision of BBC Entertainment, which would include the online channel BBC Three, and pop music station Radio 1,” reported The Telegraph newspaper . . . .

In the current transitional environment, it is impossible to see just where broadcast radio will be in 10 and 20 years’ time. The BBC’s prediction of an inevitable “Internet-only world” notwithstanding, there are still many parts of the Third World where one-way radio broadcasts remain the only economical, effective way to reach mass audiences; no matter what advances are being made in 4G-and-beyond smartphones in the First World. Add broadcast radio’s resiliency in the face of natural and man-made disasters — compared to the frequent overloading and failure of cellular telephone networks during such incidents — and the notion of shutting down broadcast lifelines seems unlikely in these regions.

The demise of broadcast radio has been predicted many times in the past 50-60 years and yet it remains. Still there is a growing mindset in what I call the Western culture’s business mindset that the pervasiveness of the Internet is the dominant factor in future media decisions. This is the same justification for various governments reducing or eliminating SW Broadcast budgets. After all “Everybody has the Internet now!”

This is a mistake, and belies a Western-centric view of the world. I cannot claim to know the real numbers, but I have little doubt the numbers representing Internet availability are inflated, partially because of assumptions and partially for selfish business interests.

In an ever-competitive entertainment market broadcasters (and governments) are naturally worried about such things as market share and the like, but this is only looking at things from one side of the coin. Anyone who uses the Internet outside of the home knows data fees can become enormous, and therefore we watch just how much traffic we pass through our wireless devices. (Yes I admit it – any place I go regularly which has “free Internet” gets loaded into my list of networks so as to keep my data charges down.)

How many people are going to listen to radio streams like they do now to radio broadcast stations? Are you going to drive home with your radio on through the Internet? I doubt it. Similarly how many people listen to the radio in places where there would be no coverage of wireless? I believe the market share would decrease rather significantly in these same western cultures where the Internet is indeed plentiful, but not certainly not free.

Having been involved in the early days of the public Internet back in the 90s, I remember meeting with city planners when they were looking to offer free Wi-Fi within the city so everyone could have access. While the idea sounded good, the logistics of equipment, and more importantly the expense of such an ongoing system, quickly laid such plans to rest for most government budgets.

I hope the pendulum swings back over time and business leaders and government officials recognize the value of both shortwave and OTA radio broadcasts. The Internet is a shiny diversion to be sure, but it is not the answer to all of our media needs. And whether folks like to admit it or not, the Internet is a fragile thing. As the old saying goes, a chain is only as strong as its weakest link. How many times a year does your Internet service go out for no apparent reason, much less because of weather or other disasters?

Broadcast radio needs to be supported for many of the same reasons as shortwave radio – there simply is no more reliable way getting information out to the most number of people over the greatest possible coverage area.

A.P. Richards’ 1939 thesis on the Crosley WLW Model Super-Power Radio Receiver

In response to our recent post about the Crosley WLW Super-Power receiver, SWLing Post contributor, Larry Hagood, writes:

A photo of Dr Richards from the class of 1927.

I am an EE student at Oklahoma State (Formerly Oklahoma A&M)–the school where the designer of the WLW [Super Power receiver], Amyle Richards, got his BSEE in 1927.

[Richards] wrote and submitted a masters thesis on the design of this radio, which earned him a PhD!).

I found a picture of him in the Engineering South building and found him in the 1927 yearbook in the library.

Anyway, the archive department located his paper on the WLW and is scanning it for me.

Many thanks to Larry for doing the research and sharing a scanned copy of Dr. Richards’ thesis about this Crosley benchmark receiver!
