Clandestine Stations / Radio Dp Li Sng Ni
« on: August 23, 2020, 1243 UTC »
9670   TAIWAN. Radio Dp Li Sng Ni (clandestine) - Paochung. At 1228, siren jamming fired up before the broadcast started. S/on 1230 with clear ID and opening anncts in Vietnamese. Fair signal but splashy QRM from the powerful CNR1 jammers on 9680 and 9660. Aug 23.

Clandestine Stations / Echo of Hope 6255 and 9100
« on: August 23, 2020, 1241 UTC »
6255   KOREA REP. Echo of Hope - Suwon-Osan. At 1140 with Korean discussion program, female speaker doing all the talking, and male speaker responding with hmm..hmmm (reminds me of home!). A series of canned anncts at 1148. Lovely signal with no jamming and // 4885 also heard, Aug 23.

9100   KOREA REP. Echo of Hope - Suwon-Osan. Noted at 1151 with Korean discussion but not as strong as the parallel 4885 and 6255 kHz. Aug 23.

Shortwave Broadcast / PNG - R. Madang
« on: August 23, 2020, 1240 UTC »
3260   PNG. R. Madang. Soft laid back songs at 1032, anncts and numerous mentions of NBC at 1042. Then a native choir (a hymn?) with some pretty wobbly harmonies. Still going with continuous choral music at 1107, fair signal, Aug 23.

Not really odd. The broadcasts are funded by a group calling itself the "Foundation for Democracy in Vietnam", which is probably Vietnamese nationals disaffected with the current regime and has nothing to do with the US Government's State Dept. It's a similar situation to the Qu Me Radio operation, which is based in France.

Equipment / Re: RETRO RECEIVER REVIEW #14 - The MURPHY B40
« on: December 30, 2018, 0238 UTC »
I asked Craig (the author of the article) if it was difficult to tune and what the sensitivity was like. His response:

Quite easy to tune, but you need to recalibrate the pointer to a reference frequency after band changes.

Its not going to measure up to an NRD or Icom in the sensitivity stakes, but with a 10dB preamp ahead of it, Its good enough for DX work.  Usual warm valve sound, and seems to ride over the noise OK.  I use it a lot, mainly for background listening.


Traveling Wave - Thanks for the YouTube link - most interesting!

Propagation / VOACAP SHORTWAVE PREDICTION TOOLS
« on: September 29, 2018, 1043 UTC »
Heres a little review that may be of interest to a few here in this group.

VOACAP is a professional online high-frequency shortwave propagation prediction application. And it's one of the most useful do-it-yourself tools for amateur radio operators, DXers and shortwave listeners.

Recently, there have been some layout changes to both the HFBC and amateur radio models of the app. This review covers the benefits of this app and looks at the new layout.

Equipment / RETRO RECEIVER REVIEW #12 -The YAESU FRG-100
« on: May 12, 2018, 2223 UTC »
Like the cat that has nine lives, the Yaesu FRG-100 is one receiver that just hung on year after year. Yaesu just couldnt kill it! Here's a review I've just completed of a receiver that I have owned for nearly 20 years, and it's one I love taking on DXpeditions.

Shortwave Broadcast / Ozy Radio Returns...again!
« on: May 09, 2018, 0633 UTC »
My thanks to Ron Howard (CA, USA) for the heads up on this one. A message to Ron from Craig Allen (owner) at Ozy Radio advises that the broadcaster is now back on the air with 1 kW on 4835 kHz. The signal here at 0600 UTC today (May 9) was weak into Mount Evelyn. But it's only 4pm local, so should be much stronger here by 7pm.

The station has been missing from 4835 since around the end of March. Prior to that, it was on 5045 kHz.

Clandestine Stations / R. Free North Korea
« on: April 25, 2018, 0217 UTC »
15630   UZBEKISTAN. R. Free North Korea - Tashkent. Long Korean talks at 1250 to s/off 1300 after ID and closing anncts. A grumbly jamming sound noted in the background but generally a poor signal on Apr 22.

Clandestine Stations / VoTibet - 11517, 11507 and 11603
« on: April 25, 2018, 0217 UTC »
11517   TAJIKISTAN. Voice of Tibet - Dushanbe. Long talks in Mandarin at 1203. Sudden change to 11507 kHz at exactly 1207. A few seconds of music on the new frequency then a continuation of the talk. Fair signal on both frequencies and no jamming noted either here or on the Shenzhen SDR..so I dont know why they bother with the change! Apr 24.

11603   TAJIKISTAN. Voice of Tibet - Dushanbe. Tibetan service at 1250 with talk and occasionally interrupted by chanting and drums. Pop song at 1255.
