I wonder if any of you are experiencing the same as I when receiving
FM on the KX3?
Using a 144-28 MHz transverter, audio on FM is raspy in nature even
with strong signals. I compared with my K3 on FM using the same
transverter and have much better sounding FM reception on the K3.
Running the KX3 preamp I get similar signal sensitivity as I get with
the K3 (preamp off).
I tried tuning off frequency to see if that was the cause - its
not. Transverter has PLL LO so locked < 1-Hz. K3 runs <2-KHz AT
28-MHz. I have not measured the KX3 frequency at 28-MHz, but runs
about 50-Hz low at 50-MHz.
This was with firmware 1.40. I upgraded to 1.50 but have not tested
since doing that as the transverter has been pulled for sale.
