Yesterday afternoon, I installed new KSYN3A Synthesizer Boards in
my two K3's. This morning, tuning one of the rigs across a dead
6 Meter band, I can hear a weak increase in white noise whenever
I turn the VFO knob. I didn't notice that yesterday morning.
Perhaps the new synthesizer board has reduced the Rx noise
threshold such that I can now hear that noise? This particular
K3 is s/n 059, and I know there is a VFO Noise Reduction Mod
available, but that mod describes the noise as "ticks." The
noise I'm hearing is a small increase in white noise, even with
the 6 meter beam connected.
The noise increase is obvious, but subtle, and I wouldn't
consider it a hindrance to operation, but it has raised my
curiosity as to why I am just now hearing it.
Ideas would be appreciated. Thanks in advance.
