During CQWW-160 one of my K3 XCVRs all of a sudden had a significant
increase in the noise level. The result was a MUCH decreased S/N level such
that I could not copy anyone calling me. After checking around the house to
see if anyone turned on something I started troubleshooting the K3 and
various cable connections. Finding nothing wrong I then swapped everything
that I had hard wired for the single band contest to my other K3.
(beverages, antenna, key, YCCC SO2R port, etc.) This cost us over 30
minutes right at EU peak run time. The result was amazing - NO NOISE. So,
we continued the rest of the weekend on K3 #2. Now that the weekend is over
it was time to address K3 #1. The problem does not seem to be as bad now
but there is a difference in S/N that can be heard with my ears between K3
#1 and K3 #2. Most everything is common to both rigs except for the power
supplies which I swapped this morning with no change noticed.
I have checked all settings on both units to make sure they are exactly the
same. They are. Both units have Sub RX, upgraded K3S synthesizers, same
XTAL filters and running the latest version of firmware.
Suggestions??
Questions??
Thanks and 73,
Bruce N1LN
