New Datamodes programme on BC bands

Starting on Wednesday 25th of July 2018 at 1830 UTC, there will be a new 30 minute programme featuring various datamodes, such as SSTV and some of the more complex and interesting PSK modes.

The programme is called ‘SLOW SCAN RADIO’, and will go out on 6070 kHz AM via the transmitter of German based relay station Channel 292, and should be audible throughout many parts of Europe.

Bill tunes to WWFD in AM HD

Many thanks to SWLing Post contributor, Bill Mead, who writes:

Thomas, I’m sending you a short clip from WWFD 820 kHz in Frederick, MD. It’s America’s only all-digital station, apparently. They are HD only with a relatively eclectic music format. I’m hearing them at my QTH in Harrisburg, PA, about 80 miles or so north of their transmitter which is 4.3 Kw daytime. I sort of doubt they’ll come in at night when they drop down to 430 watts, but who knows.

My experience with HD on MW is that it can be heard at pretty decent distances under ideal conditions but the slightest bit of interference, a lightning strike or someone switching on the lights for example, and it’ll lose the HD lock.

My HD receiver is a Sony XDR-F1HD. It’s well-known as an excellent FM DX machine. What’s not as well-publicized is that it’s a very decent MW receiver as well. All it needs is a good MW loop antenna directly connected to the AM ANT terminals on the back of the radio.

Excellent!  Thanks for sharing, Bill. I’m passing by Frederick, MD in a couple of weeks and plan to tune to WWFD in both my car and with the Sangean HDR-14.

Lilian decodes SSTV images from International Space Station

Many thanks to SWLing Post contributor, Lilian Putin?, who writes:

Greetings, my name is Lilian Putina and I am from Moldova. I’ve been following your blog for a long time, with the help of it I’ve purchased a short wave radio, SDR, and WRTH almanac.
I take everything a little bit: shortwave, FM DX, weather images from meteorological satellites, decoding of NAVTEX, WSPR and FT-8 etc.

I’m sending you two SSTV images received from ISS on June 30, 2018.

Many thanks, Lilian!  I’m also very pleased that you’re enjoying all aspects of radio–to me, that’s what makes this all so very fun!

Al decodes SSTV image from International Space Station

Many thanks to SWLing Post contributor, Al Holt, who shares the decoded SSTV image above via Twitter and notes:

A two-fer, excellent!! Here’s what I caught during its pass over Florida @ ~0914z, a 3-star pass. Had my HT on freq. but dropped it on the floor and got a burp which produced the break in the upper 1/3 of the image…Doh! -73

Ha ha! Thanks for sharing, Al! Based on such a short gap in the image, you must have recovered that HT rather quickly!

Post readers: Has anyone else decoded SSTV during an ISS pass?
