Shortwave Radiogram, 9-12 May 2019

WINB in Pennsylvania has added a new transmission time for Shortwave Radiogram: Thursday at 2330-2400 UTC on 9265 kHz (analog). Previously, I was finishing up the production of Shortwave Radiogram at about this time on Thursday. I’ve moved production ahead a few hours, so it’s uploaded to WINB for today’s broadcast. If reception is not good, or nonexistent, has …

Shortwave Radiogram, 3-5 May 2019

Last weekend’s Shortwave Radiogram was a reminder of the ability of MFSK16 to provide a correct decode even in difficult shortwave conditions. Thank you for your reception reports, especially listeners in Japan who decoded, or attempted to decode, the excerpt of Japanese text. (See this example from Sakaé-san in Joetsu-City, Niigata Prefecture.) Sometimes, even the MFSK16 was not able to …

Shortwave Radiogram, 26-28 April 2019

Last weekend’s Japanese text was decoded in Japan, in some cases partially, and in others 100%. This weekend, we will try another brief excerpt of Japanese text, but this time in MFSK16, which is slower and more robust than our usual MFSK32. We will also raise the center audio frequency to 2000 Hz to try to escape any interference from …

Shortwave Radiogram, 19-21 April 2019

Too late for last weekend’s email, I was informed that the Friday 2030-2100 UTC broadcast of Shortwave Radiogram was replaced in the WRMI by a religious program. WRMI has provided this  replacement time slot: Friday at 1300-1330 UTC on 15770 kHz. This is directed to Europe. See the new transmission schedule below.   I am still exploring opportunities for a …

Shortwave Radiogram, 12-14 April 2019

Last week was a difficult week for Shortwave Radiogram. The transmission from Bulgaria Saturday at 1400 UTC was canceled too late for me to notify you in the weekly email. It is uncertain whether a Shortwave Radiogram broadcast from Bulgaria will be restored. I am exploring other transmission possibilities. For now, best reception in Europe is probably Saturday at 0230 …

Whither Digital Radio Mondiale?

In a recent issue of QST, Steve Ford, WB8IMY, took a look at the forgotten Digital Radio Mondiale (DRM) system. Digital broadcasting was supposed to be the life preserver for international shortwave broadcasters facing the reality of rising costs and shrinking audiences. In 1998, broadcasters, equipment manufacturers, regulators, and others formed the DRM consortium to create a specification for digital …

No Shortwave Radiogram today 1400-1430 on 9400 (and more…)

I have just been informed that Shortwave Radiogram will not be transmitted today (Saturday), 1400-1430 UTC, 9400 kHz, via Space Line Bulgaria. This is due to “unresolved scheduling issues.” Future broadcasts of Shortwave Radiogram via Space Line are uncertain. ———- Also no signal from The Mighty KBC Radio on Sat April 6 1300-1400 on 11600 SCB 100 kW / 306 …

Shortwave Radiogram, 5-7 April 2019

Apologies for the missing transmission last weekend on 9400 kHz. I hope the Saturday’s 1400 UTC broadcast is heard this without mishap. During the broadcasts that were heard, our experiment with simultaneous English and Spanish text, using side-by-side MFSK32 streams, worked well. The dual audio caused mixing products that made the signal look somewhat messy on spectrum displays, but this …
