KRX3 No signal from main antenna

[Paul Franson-2]

Just installed my KRX3.
With the sub receiver set to main ant, it sounds like there is no
antenna connected to the sub rcvr.  If I switch the sub rcvr to ATU and
connect the antenna to Ant 2 it works fine.
MCU is 2.58 and DSP1 & 2 are 1.94 - just reloaded them.
Did I miss something?

Thanks for any help.

Check that you removed jumper W4 and that the SUBIN interface board and connector pins are correctly seated.

Solved - in case anyone else has the same problem:  On the sub-in board
one of the leads on T1 did not have the paint removed, looked like a
good solder joint until I got the magnifying glass out.  Removed the
solder, cleaned off the paint with an Xacto knife, resoldered it, now
working like it should.
