Don, At first I thought your suggestion didn't affect anything since I already had dressed the leads fairly well. However, in bypass mode (less than 10 watts) the IMD is now back to -30 dB. Also, after running for about 15 seconds, the IMD at 25 watts now drops to about -27 dB.
So there is now a noticeable difference between bypass and KPA100 mode and, I suspect, a difference in my SSB performance as well. Any other good thoughts like that one?
