Michael,
Thanks for the reply.
I have not yet adjusted the carrier oscillators. On LSB and USB they sound about right to my ears as is, just listening to band noise and to some stations. I will trace the path for CW to get to the bottom of why RF output is low on TX for that mode.
If you have a booster amplifier that you have broken for spares then I may be back in touch regarding the Japanese 'Jones' plug if I cannot come up with a solution. Likewise the S-meter. Are you in the US?
