[Elecraft] K3 Sub RF gain

[hb9brj]

I always experienced a significant difference when comparing main/sub signal
levels.
Mike's message triggered me to search for the cause.

Step 1: Changed RF/AF controls back to independent:
SQ MAIN = 0; SQ SUB = 0; SUB AF = nor.
No luck, the sub signal level was still much lower than main.

Step 2: Filter parameters. The filter loss compensation values did not
match!
Forgot to enter gain values after having added more filters to the sub RX.
Using the K3 Utility I copied the filter gain values from main to sub.
Same bandwidth = same gain value in both main and sub.

Problem solved: At identical settings (PRE, ATT, RF/AF Gain), main and
sub signal lelvels are now fully identical.
