I put a trimpot on mine, to temporarily seek the right value
(replaced with fixed resistor
after experimentation) and I ended up with something like 680 ohms
as I recall.
Yes, I dispensed with the trimpot and went directly to 1 K for R98.
This has made the shifts considerably smaller, but they are still
bothersome.
I'm going to try a larger value, such as 1.5 or 2 k next time I have
the K2 apart. I made need to make some changes to T1 and T2 in order
to avoid decreasing the overall TX gain.
