Just finishing off breadboarding a 12 parts QRP transceiver (plus hi-Z earpiece, xtal and key) for 80m CW. The name is the uu80b.
It is crystal controlled on both RX and TX and the inspiration was the Curumim rig from PY2OHH (see earlier post). TX output is 450mW. The xtal controlled regen RX seems to be quite sensitive too. Unlike my FETer, this rig is full break-in and needs no multi-way TX/RX switching. I have already seen and heard the TX part on the on-line Twente University SDR which is 150 miles away from here in Holland. The rig uses just two 2N3904 transistors and a handful of standard parts.
Currently it is on 3.579MHz but this will be moved to 3.560 as soon as I get another crystal next week. Skeds welcomed!
Isn't ultra-simple QRP construction magic!
