Icom IC-736
Receiver IN / Receiver OUT
This is the little feature that
enables you to insert another device into the RX path of the
TCVR.
It can be preselector, attenuator, etc. It is also the best place
for a switch that toggles between the main and alternative ANT
(such as beverage) for RX.
I removed the antenna tuner and
drilled two holes in the rear panel:
Then I mounted two CINCH (RCA)
sockets and soldered coaxial cables to them:
I made a sticker (self-adhesive
lamino) to mark the two new sockets:
The coaxial cables are terminated
with connectors used in the TCVR, one male and one female.
Thanks to this it can be inserted into the original RX path. Look
for the coaxial cable coming
from the ANT relay to the MAIN board:
And of course for a normal TCVR
use the sockets must be interconnected with a short jumper:
