[Elecraft] KX3: on FM

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.
