The best speaker I found for my K2 in the shack is the Heathkit HS-1661 that
goes with DX-60 and many of the other Heathkit radios. Somehow, over the
years others have found it quite suitable for service other than Heathkit
radios. Nice full bodied sound and tone.

Ed your SDR-IQ will do a nice job of close in 2 tone ID testing, a
better job than my simple spectrum analyser. For IMD testing you do
not need a resistive coupler, an ordinary oscilloscope probe used with
a couple of turns of wire around the output coax outer will provide
sufficent signal for IMD
Hi Jim,
I think it may be a fact of life with alarm systems since they have wiring
all over the house. On mine, high power would signal an alarm identified as
a fire alarm. I identified the wires in the alarm panel that went to the
smoke detector input screw terminals and added a clamp-on ferrite

That's noting unusual. Almost all amps are sold that way, with
operation up to 22 MHz and a separate user-mod kit that can be

I have to agree the Heathkit HS1661 is a great external speaker for the K2.
I have used it for over 8 years and been very pleased with the audio output
and quality of sound. I liked the HS-1661 speaker so much I removed it
from its Heathkit case and built a separate enclosure for it to match the

For computer interfacing the KX3 for running various soundcard

A very important consideration when measuring the IMD performance of an

intermodulation products generated by the test equipment must be low enough
so that they do not introduce measurement error. Among the usual sources

I'm in the contract electronic manufacturing business and I've been with

Thanks, Gary. Yes, they do great work. We always hope that boards will
turn out perfectly in fabrication, and this time it didn't, but the
