I have been reading the mail of this reflector for some time, and thought I
would join today and include my two cents; after all I own so2r K3/P3/K-Pod.
However, I do enjoy other radios, mainly an IC 7600 which isn't a K-3 in
handling strong signals but it does just fine here is rural Idaho, and the qsk
is just as good. Shamelessly, I like the colorful screen.
On K3 audio: After finishing the build on a K2/100 recently (a field model
purchased in 1998 and never completed) I was surprised at the overall
performance of K2 and decided that K3 can have too much gain. I now have no
gain on each filter, and 2db on the 200 hz one. If K3 seems noisy then after
adjusting agc and RX EQ (like most others I have the cw offset at 500hz), you
may want to use 0 gain on the filters. Maybe this point about I-F gain has
been covered but if so I don't recall reading about it. Moreover, I don't
normally use a preamp 160m through 20m, except on beverages.
K2 does not have objectionable phase noise as I read somewhere, that noise is
the need to do the keying modification. K2 is a real sleeper of a radio, and
it taught me something about K3. Of course you have to build it, but K2 is
contest competent though with far fewer features than K3.
BTW, I had no difficulty getting the parts to finish K2, including the keying
modification, 18 years later.
