Title: speech synth + Kahn ssb tx on arduino
Post by: Quinta on September 19, 2021, 1654 UTC

We can made speech synth on Arduino with Talkie library https://www.arduino.cc/reference/en/libraries/talkie/
Also we can produce SSB, (also AM and FM) with arduino and si5351 without filters and phasing nets https://antrak.org.tr/blog/usdx-a-compact-sota-ssb-sdr-transceiver-with-arduino/ with efficency of E class transmitter.
I think should be a way to merge this projects. I mean made a beacon with arduino, si5351 and some transistors, which can speak telemetry in SSB on any frequency in 3.2-50 mhz (minimum, i think frequency range should be much wider). Cheap, simple and power efficient device.
I made both devices, arduino speech synth i use in speaking 27 mhz feral beacon https://www.youtube.com/watch?v=yyRJJnI8Hxg
And i made uSDX transceiver https://www.youtube.com/watch?v=9DjDdcnP0GE
It was not difficult.

I have been working with Arduino in my transmitters and receivers. Nice work. Keep us informed on your progress.
