Are you a ham radio operator and/or SWLer that would like to dabble in DRM (Digital Radio Mondial) but don’t have a purpose-built receiver? A friend recently brought to my attention a clearly-outlined DIY photo instructional for a modification you can make to the classic Icom IC-735 ham transceiver to add a 12 Hz downconverter and I.F. output jack.
If you’re handy with a soldering iron, view the PDF instructional created by Matthias Bopp (DD1US) for making this modification. The downconverter (along with many other DRM items) is sold by German firm, SAT-Schneider–follow this link to purchase it online for just 25 Euros.
Though the IC-735 is primarily a ham radio transceiver, it has general coverage and makes for an exceptional shortwave broadcast receiver as well. In fact, I have an IC-735 in my shack and use it primarily for SWLing. This unit was produced by Icom in the 1980’s; many are available now in the used market for around $325-450US. A great value for the money, especially if you also happen to be a ham.
Radio St. Helena has announced that their annual Radio St. Helena Day will be held on November 14th, 2009. If you would like to try your shortwave listening skills, this is a fun event indeed. DXers around the world try to tune into the annual broadcast and snag St. Helena’s unique QSL card.
Below is the full press release from Radio St. Helena:

Radio St. Helena is very pleased to announce that the newly designed RSD 2009 QSL cards will be sponsored by the highly respected Japan Short Wave Club. This good news has been reported by Mr. T. Ohtake of the JSWC. It can truly be said, that without the very generous help of the JSWC, there would not have been a RSD Revival in 2006.

The last two lines of the above address are very important and should be written as shown. Be sure to use sufficient postage on your letter to RSH. Ask at your local post office for the correct AIRMAIL postage for your letter to go all the way to St. Helena.
Emails and telephone calls from DXers everywhere are very welcome during the broadcasts.
A special email address for RSD 2009 will, probably, be announced in October.
Gary Walters and his Team at RSH wish everyone excellent listening conditions, hope that you enjoy the programming, and hope that the sunspots will be kinder to us this year.
With best 73’s,
