Interesting interview. I had a Kantronics interface card for my Atari 800 back around 1983 - I built tone decoders & encoders for RTTY and worked my first RTTY with it.

Took this podcast on my morning bike ride today. Great conversation, but was hoping to hear some discussion of the 8040a DC receiver and I think there was a companion transmitter. 73

Hi John. It's been so long I don't recall much about the 8040 RX. I'll hunt around...think there are some pictures. There was a little QRP transmitter that some guys used...it was called the (original) Rock Hound and it used a xtal in a logic oscillator for the frequency source. That was feed to four OPEN COLLECTOR NAND GATES IN PARALLEL for a whopping 3 or so watts. This little thing was powered through the KEY to a battery of all things. I've seen the schematic on the web a few times..........might try searching "rock hound tx" or...... thanks, John. Phil W0XI, Lawrence KS......Look for me on 20 meters, usually around 14030.........73 !

I have a device that has your call (W0XI) on the pc board but I have no data as to the purpose of the unit--It is new-unused but with no documentation. On the pc board are the words (REV 2 ECI CW BPF REGEN W0XI 4-3-13-6-10. It is powered with a 9VDC battery. What can you tell me about the unit?

I was given a a little device that has W0XI name on the circuit board (as the 'producer') and a production date of 4-3-13. There was no literature with it . Can anyone tell me what ham magazine might have featured an article about the unit? It looks like a commercial produced printed circuit board.
