Without looking at the circuit, I would *guess* that the
resistors were placed there to suppress any spurious
oscillations.? It's also a place to measure current flow
in some circuits by measuring the voltage across
the resistor.

Well that was disappointing.......
Instead of paralleling a second
10 ohm resister across each of R30 and R31, I went for broke and simply
bridged them out of the circuit.
As nearly as I could tell it made no
difference at all in either the received signal level nor the level of the
noise floor. And I was watching both with 1 dB resolution...... there was no
change. So obviously I do not understand all I thought I knew about the
circuit.
So what would I change to add 6-10 dB of gain to the op amps
for a test?
