April’s collection of Japanese language WebSDR recordings for December 2020

Many thanks to SWLing Post contributor, April TimeLady, who shares her latest collection of Japanese language WebSDR recordings–this time, for December 2020. April notes:

Please find in this email a link to another batch of SDR recordings I have uploaded on archive.org that I made over the course of December.

I concentrated mostly on mediumwave stations to get Christmas music, and I also have New Year’s recordings in it too. I also have shortwave recordings too, but not as much as I have in the past few months.

Feel free to listen to her recordings via the clickable playlist below, or on her Archive.org page.

Thank you, April for once again uploading and sharing your recordings!

Dan’s thoughts on a Panasonic RF-9000 up for auction

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

Appearing on the Japanese Buyee website is this RF-9000, which was the “King of Radios” of the heavy multiband “portable” era.

In recent years, RF-9000s in excellent to LNIB condition have sold for $10,000 or more.

A tour d’force of technology in its day, the 9000 featured room-filling main speakers and PLL technology that was advanced for its time.

The shortwave receiver section of the 9000 was plagued by PLL artifacts which prevented the radio from achieving what it could have had this problem not been solved in advance by Panasonic engineers.

A LNIB RF-9000 that I purchased for near $5,000 sold to a Hong Kong collector for $10,000 a few years ago. While I do miss its amazing FM quality and looks, the receiver ultimately lagged behind others, such as the SONY CRF-330K and 320 in performance.

The asking price for this 9000, which appears to have cosmetic issues, is in my view high.

Thank you for your insights, Dan!

Any off-air recordings of “The Famous Computer Cafe”–?

Many thanks to SWLing Post contributor, Devin, who writes:

I am a game historian conducting research on early computer games. There is one radio program of particular historical significance called The Famous Computer Cafe that interviewed all the early movers and shakers of early computing, including Philip Estridge, Bill Gates, Bill Atkinson, Gene Rodenberry, and Stewart Brand. The show ran from 1983-1986 primarily in the Los Angeles area, but was distributed nationally over NPR starting in 1985. Only one recording is known to exist, along with a few transcripts, as the original tapes were lost years ago.

Here are more details on the show:

“There were several versions of the show, which aired on several radio stations, primarily in California. A live, daily half-hour version allowed phone calls from listeners. Taped versions (running a half-hour and up to two hours) also aired daily. The show started in 1983 on two stations in the Los Angeles area: KFOX 93.5 FM and KIEV 870 AM. In 1985 it began airing in the California Bay Area: on KXLR 1260 AM in San Francisco and KCSM 91.1 FM in San Matro, and KSDO 1130 AM in San Diego. [Note: KIEV ran 3:30-4pm M-F and KFOX 7:30am-8:00am and 6:00pm-6:30pm. I do not have information on the times for the 1 hour show.]

Also in 1985 a nationally syndicated, half-hour non-commercial version of The Famous Computer Cafe was available via satellite to National Public Radio stations around the United States, though it’s not clear today which stations ran it.”

I was hoping the Spectrum Archive might have some recordings within some of your files, particularly from the LA area. What additional information would I need to provide you in order to better locate some recordings?

Thank you for your help,

Devin

Thank you for your inquiry, Devin. I’m a huge fan of early personal computing and game broadcasts, but never heard the The Famous Computer Cafe. Unfortunately–as I mentioned via email–the Spectrum Archive nor the Shortwave Radio Audio Archive have any recordings of the program.

I’m willing to bet an SWLing Post reader may be familiar with the show, however.

Post Readers: If you have any information that could help Devin, please comment on this post. It would be brilliant if someone actually made an off-air recording of the show back int he day.

Rob Sherwood tests the new Yaesu FTDX10

Many thanks to Rob Sherwood (NC0B) who shares his recent assessment of the new Yaesu FTDX10.

In short: the FTDX10 is now number 3 (at time of posting) on Rob’s receiver test data table— a table sorted by third-order dynamic range narrow spaced. Most impressive!

FYI: I plan to review the FTDX10 this year.
