Hello David,
If a PSK signal is generated in an early stage of a transmitter (or is fed
into an input of a transmitter), then all of the transmitter's stages which
follow should be linear to keep the signal clean. In the case of the
basic type of PSK 31.25 signal consisting of a single tone,
Oooops :-( In my message to David Moes, I said:
phase results in sidebands spaced
31.25 kHz each side of the main signal. If the transmitter's stages which
follow are not adequately linear, then IMD products could create
splatter.
I meant 31.25 Hz not 31.25 kHz.

I built a K2 more than 12 years ago, and over time added most of the

ago, I found myself in your situation, another K2 or order a KX3
when it was released. I ordered a KX3 kit a few hours after Elecraft
started taking orders.
Personally, I'd go with a K2 unless 6m is important to you, but I'm
biased ... I love my K2 for field events. With a KX1, K3/KPA500/P3, and
a KAT500 on order, I'm going to have all the E-radios I'm likely to need
or want. KX3 is really attractive and I can understand all the buzz
about it,
Hi Stan,
The K2 has an optional internal 100-W amplifier and is of course a
full kit. But if 12 W is enough power for your planned usage, and you
wouldn't be building the K2 anyway, I'd suggest going with the KX3.
The KX3 has several advantages: 160-6 meter/all-mode coverage, much

In my case, I did not notice any alert. I placed the kpa-500 in STBY and

True building is winding toroids and making hundreds of solder joints plus
