First, if I use headphones the CW sidetone on transmit is painfully loud unless the volume level is very low.? Is there some means to reduce the sidetone to the headphones, or should I just not be using headphones??
Change the R253 from 10K to something like 100K or even 220K. I know it is painfully loud, our apologies to the early birds. i will ask the beavers to change that resistor in the next batch.

Next, there is a significant pop in the headphones at any volume level when I push PTT---loud enough to make my ears ring.? Basically I can't have the headphones on when I press PTT.? I'm using the supplied electret mic wired between tip and ground, with PTT between ring and ground.?? Is there some obvious mic trick I should be trying to prevent this??
i haven't experienced this pop. i hope this is not a 'feature' of this rig too :-( anyone else who has reported this?
?
My third question is regarding power:?? has anyone been able to measure the power output on 20m?? I only have an MFJ 5W QRP wattmeter, and it's a bit....qualitative.? I can verify greater power output at lower frequencies, but I can't get an absolute power measurement.?
It gives me 6 watts as measured on a 20 x 50 ohm (2 watt) resistors parallelled up. through a sniffer.
