Thanks for the tip Lee, it got me to looking at the TX mixer / buffer part of the chain. The ALC / BFO line into the mixer is consistent across bands, (however the micro controller quickly drives the ALC to max at 28 mhz). The mixer output looks ok, as well as the output on pin 6 of the buffer. However when I measure of the cathode end of D6 the relative output is down, as if the bandpass filter is sinking the energy.
