Well, off to a good start today with a couple of QSOs with the 2 transistor XBM10-2 60mW 10m CW transceiver. Much to my surprise I got 439 from IT9QAU/QRP at 1547z today. Distance was 1414km.
Then 599 (with chirp) from M0DRK, who is in the same village as me. So 2 DXCC countries worked already. On receive, the oscillator will not always start in the latest circuit version in which I've reduced the component count by a further 2 parts (just 11 parts plus crystal and earpiece now). Still, a very promising start for something so ultra-simple.
UPDATE 1850z 20.11.10: To get the oscillator to always start on RX, to get TX spot-on 28.060 with the right offset for RX I had to revert to the earlier design and put 2 parts back. The revised schematic is shown here. This IS such fun.
