Screen shot of DumpHFDL running from QTH in Florida, USA. Happy to have it working again; I had put a lot of time into getting running. Upgrading to the latest release (Kinetic Kudu) of Ubuntu got it working again. Using SDRplay's RSPdx, long random wire antenna & Dell 9020.

A collage of images from Shortwave Radiogram received here last night...

And Shortwave Radiogram's broadcast on 15770 kHz Friday. My location gets lots of multipath (echo) on this one. Also, lots of backscatter being in the skip zone of WRMI. SwRg: text & images over analog shortwave.

A holiday parade of lights in MFSK64 this week on Shortwave Radiogram. Received in northern Florida from WINB's transmission Friday 0030-0100 UTC on 9265 kHz.

The new build of RaspiNOAA is giving good results with M2 images. With the older build about all I got was a single B&W image. Nice!

A nice view of clouds in the Atlantic from NOAA 18 earlier today.

My decoded reception of Humphrey Bogart as Rick Blaine from "Casablanca." transmitted during the program. "Play it again, Sam!"

Another recording of multipath reception in FL of Shortwave Radiogram & Kim Elliott's intro yesterday's broadcast @ 1300z on 15770 kHz.
Note: lots of Asian broadcast stations showing up here in FLorida mornings on 11, 13, 15 MHz!

Audacity playback of introduction to Shortwave Radiogram broadcast today at 1300z on 15770 kHz. Notable long path echo (multipath) here in northern Florida. WRMI xmitter also in Florida, just further south.
Interesting how the baseline of recording is modulated by the delayed signal. Most of the images were decoded.

A "heads-up" on a special event station, W9N, celebrating the Max Headroom TV Jamming Incident. I just worked 'Max' on 20m FT8. More info on: twitter.com/w9nmaxheadroom
GGGGood LLLLuck!

I'm a frequent listener to Shortwave Radiogram, a program that uses MFSK digital modes to transmit text and images over analog shortwave transmitters.
Great reception today of the 1530z, 9955 kHz broadcast over WRMI in FL, USA. A couple of images sent in MFSK64...

Got my first QSL from W9G the Godzilla Special Event station that operated over the weekend. Worked them on several bands.

@arth I forgot to mention KiwiSDR's have an extension that is essentially DREAM. But, it's an easy way to decode them than messing with setting up DREAM from scratch.. BTW, WINB splits the normal 10kHz bandwidth with some sort of data channel. I think it only shows up on their 15750 freq. Unfortunately, that 5kHz audio channel really suffers in quality. All the best!

@arth
What you're hearing is their DRM feed. They sometimes xmit it on 9265 kHz, more often you'll find it on 15750 kHz. You can sometimes decode them using DREAM software. 73!
