pix of some QSL cards from back in the early 60s

Second picture a little rough but thats a Lafayette Radio communications receiver (kit) on left side... and an old console radio with SW band, and magic eye tuning in the center.

As i recall that old radio was hot chassis and zapped me at least once. I ran a decent length old school antenna wire between two nearby trees.

I confirmed QSL reports from Africa, Western & Eastern Europe, and South America.

Nice!
I suppose having remote-controlled receivers is cheating.

It is majorly impressive how things that needed banks of DSP cards 30 years ago can now run on a laptop. Modern high speed ADCs are also very impressive. I remember back in the late 90s the old guard were saying that single down conversion zero IF radios weren't possible for cell phones then suddenly there was the leap in coverter tech that made it not only possible, but the best solution.

I really like how it "Hoovers" (vacuums up) the entire 25 MHz spectrum so you can see what band is active.
The waterfall display is way cool.

I found a network of receivers here: https://www.sdr.hu/

I must have been way, way, way, way ahead of my time when I did this back in 1993. https://proaudiodesignforum.com/forum/p ... f=12&t=280
The irony is that the first station I punched up on sdr.hu was a station in Virginia where I monitored WFAN at 660 kHz.

Retransmitting WFAN is where my fun began...
