Good morning Chris -
I do not have direct experience with the speakers mentioned in your post, but I
use a pair of JBL Control 2 powered studio monitors. They are very accurate
and, perhaps most importantly, do not seem to radiate detectable RF (or be
susceptible to it).
I used, until recently, a ELAD transmit/receiver switch to protect the front
end of my auxiliary receiver. I know that MFJ makes at one model as well
(MFJ-1708), perhaps two. The ELAD switch isn't normally available in the US,
but is frequently available used and can be ordered from Europe.

Well said, John. Having designed automotive communications and datalogging
equipment with RS-232, USB and EtherNet, I am amused by some of the things that
I read in these USB vs. RS-232 threads. The days of Microsoft ruining USB on

This is another common misconception. All of the microprocessor vendors that I
am aware of have built-in USB peripherals, and often have reference drivers and
driver templates. Assuming that Elecraft uses MicroChip PICs, there are few
reasons to add an off-package USB peripheral.

I used mine in this weekend's ARRL Round-Up in conjunction with N1MM (using the
FLDIGI modem) and a sound card. The system, of which the K3 is more or less the
RF front end, worked great. It's nice to be able to pick out an S3 multiplier
station next (next-next) to an S9 +30 honker with no AGC
And 1.5 watts, through a decent antenna system, now becomes the equivalent of a
nice QRP station - covering up that DX station, when propagation is right, that
you were trying to work. Those of you with P3s shave probably already seen it
in your waterfalls - walls of noise up to 9/10 kHz wide.

Another perspective is that this part of Elecraft's business is excellent
(instead of sucks) because we get advance visibility of products. At the same
time we should realize the risk of advance notice is that factors out of
