Hi all,
 
I think I may have a problem with my K3 . I was checking my beverage antennas last week and I decided to see
if I could hear signals on my coaxes going to the beverages .
 
At night I can hear signals up to S5 on 80 m with 50 feet of coax connected to the receive input jack , coax end is open and is going underground except for the last 8 feet .
I have band reject filters inline on my TX antennas and when I manually switch the filter and TX antenna to a different band 
I can barely detect the stations that were S5 before . I tried the same with my other radio and the stations I hear are not moving
the S meter .  
Did I do something wrong in assembling the radio ?
 
Thanks for helping out

Luc,

I really cannot tell whether you have a K3 problem or an antenna problem
with the information you have provided.
If you have access to a signal generator with a 50 uV output (Elecraft
XG1, XG2 or XG3 will do nicely), first connect it to the normal antenna
jack - you should see S-9 if your S-meter is properly calibrated.  If it
is not S-9 you can calibrate the S-meter or somply note the deflection.

Next, put the signal generator on the RX ANT (turn RX ANT on) and you
should have the same S-meter deflection.

If the S-meter readings are substantially different, you have a K3
problem, but if the signal generator provides the same S-meter reading,
you have an antenna problem to solve.
