] KX3 and PX3 with 2m Transverter comments
I bought a KX3 and PX3 with a view towards using them with an external high
performance transverter for 144MHz (with an IF of 14MHz). My main interest
being weak signal operation on VHF. The ability to use the I/Q outputs with
a sound card or PX3

Thanks Jim, yes my PX3 was a kit, and I did do the tape removal and check good
electrical contacts as I was sure there could be problems. I don't like the
design of the case, would have much preferred a diecast box instead of silly
thumbscrews and legs that either are too loose or too tight. As

I don't have either a KX3 or PX3, and my 2m work is limited to FM, but
the problems that you describe could be due to various fixable problems.
For example, some P3s had spur problems due to bad electrical contact
between parts of the enclosure, as well as improperly attached BNC
connectors on

Unfortunately it looks like this is not going to work out for me, as the level
of radiated noise at VHF from both the PX3 severely masks weak signals, there
is also a huge radiated birdie from the KX3 near 144.4MHz.
Questions and observations.
