A year or so ago there was discussion about adding additional caps
to C238
to reduce IMD. I believe it was two 1-uf caps.
What was the outcome of that? Did it make a noticeable difference in
pileups
or for weak signal detection?
Very slight.
Is it a recommended mod?
No. However, there was very positive response to the AGC changes made
in firmware a few months later (rev 4.51 at the time). We corrected
two issues with the DSP code, leading to the following timely quote
from G3TJP: "It sounds like you've scored a touchdown with this
revised firmware...."
