Re: HA8SA All Band CW QRPp DC Transceiver

That's an interesting design. The TX/RX switching is clever.? Did you build it, Pete?

"A very simple direct conversion HF CW transceiver. It works on any band just need to replace LPF circuit or use a 30 MHz LPF and external tuner. On 40m I've had 17 DXCC on Europe. I had only 225 mW and reach London and Moscow too. During ARRL 10m contest I was very lucky with propagation because of I made contact two USA stations with 71 mW. I checked the out power more times because I did not want to believe. I was not wrong it was really 71 mW on 10m."
