[Elecraft] Upgrades to #3481 - what is recommended?

[N2TK, Tony]

K2/100 is up and running. Been using it on CW. Aligned the filters using
Spectrograph. This weekend will hook up a mike and start on SSB with it.
Then will hook up the Acom 2000A to it.
What a neat kit. I also installed the KSB2, KDSP2, KNB2, K160RX.
I reviewed many articles on improvements to the K2. I would appreciate
feedback as to which of these upgrades or any others that make sense for
this serial number.

KSB2
Change R14 to 10K for my Heil HC4
Change RP5 to individual resistors pin6-150k, pin5-470k, pin4-220k to help
with compression
Install 4.7k resistor between /COMP0 and U3 pin 6 to help VOX
Change the caps per KI6WX for 2.5KHZ SSB bandwidth.
Increased gain mod per KI6WX to add 2n2222 to output of U5
Reduced IMD with 2.2K between Pin 1 and 2 of U5

Control Board
I changed R17 from 3.3M to 470K. That helped with QSK

RF Board
Change R98 to 1K? Power out on 10M with bare K2 is somewhat ow on 10m. But
above 11W everything looks fine with the KPA100.
Filter Bias Bypassing - adding 6 chip caps to RP4 and RP5.
Constant Filter Output by changing T7 to 3/22 turns and T? to 22/10 turns

Tnx for any feedback
N2TK, Tony
