By CW sidetone, I ment the audio tone produced when the rig is keyed in
transmit mode. Transmit CW sidetone may be a better term for it.
The "Jones" filter is an adjustable IF crystal filter.
Yep, there is not much price difference between the 556 and 555. Since I
operate a lot of QRP I would like to have the 555 switchable 5/50 watts.
I have looked at a couple of ideas, one being to bypass the PA module
which works except that the power output then varies from 3 - 10 watts by band
module , not really too great for offical QRP contests. Well, I'll keep trying.
