[Drake] R7

[N8KDV]

I am looking for some information regarding the R7 receiver. What I want to
do is disable the preamplification for the CW filters. I am presently using
a 3 kHz and the stock 2.3 kHz in those positions. Also installed in the
radio are the 8 kHz, 6 kHz and 4 kHz filters.

In my previous R7 I had Drake disable this preamplification, which
apparently is not needed, and may make the voice filters perform better. I
have a pretty good idea of where the coaxial cables which were disconnected
are located on the underside of the main board, but just can't recall
exactly which ones they are. As I recall there were two of them which were
disconnected.

On the right side of the main board, when viewed from the front are 5 sets
of coax, I know it's not the very top one as that has to do with the
calibrator. That leaves the 4 in the lower right.

Any help, a diagram, of which ones to disconnect would be greatly appreciated!

I have not had a reply from Drake regarding this matter yet.

I swear by, not at, Drake receivers.
