Another couple of points Steve:
Take a look at the recent ARRL reviews of transceivers, the "Spectral
display of keying" graph shows the K3 to be 10 dB or more cleaner on CW
transmit than most other transceivers. This is synthesiser and general
noise as well as "key click" sidebands. These spurious outputs are
mostly not mentioned but are a real problem if you have a ham within a
couple of miles who runs more than a few Watts and are one of the
reasons multi-radio stations look to the K3 as it's cleaner transmitter
can allow CW and SSB stations to operate on the same band. I can hear a
local station 50 KHz either side of his CW transmission, he's about 2
miles away.
Two tone 3rd order IMD figures for 12 Volt transceivers are mediocre and
contribute to wide transmissions on SSB. The K3 is no better in this
regard than other brands. The IMD figures on the K3 improve by around 10
dB when running at quarter power, useful if you have a linear that gives
a decent output with a 25 Watt input.
With the K3 receiver you have one of the best receivers around, but
unfortunately the transmitters in your area can often be the problem.
Make sure your menu item "AGC PLS" is set to "nor" otherwise pulses from
light switches and similar transients can cause the K3's AGC to punch
holes in the received signal.
