Good Morning All,
Have gained an odd issue this morning. Rig is serial number 464 and
has been flawless since the day I got it. Last night was on 40M CW
DXing, all was well.
This morning got into the shack (rig is always left on) and I went to
change the band from 40m to 20m. I pressed the

Dick, are those headphones stereo? I haven't seen anything but for a

Good point...
The website states:
The CM500 includes up to nine feet of cord, a 1/8 miniphone plug and a
1/4 TRS phone adaptor for added flexibility.

They are stereo and the cords are actually too long. I've got them wadded up
behind the K3.

Hi to all the readers.
I put on my K3 s/n 1758 the interface option KXV3A two days ago, now i have
a problem with the SteppIR control box, change the frequency continually
alone without move the vfo.
I make a test with an Icom 756 pro 3 and the control box work fine !
Any ideas

GD,
Would someone either send me the schematic wiring for the S13 cable,
or point me towards it on the internet.

What is the preferred push to talk switch to go with such an
arrangement? Are there any recommended footswitches?

I use VOX for all SSB operation, including contesting. It's very
easy to adjust K3 VOX settings to work quite well.

A switch is a switch... it comes down to comfort and durability...
many discussions on the topic here:

Dick,
While a broadcaster - I usually purchased foot switches from either box
houses like BH or music stores for guitar amp control.
They should be in the $15 range with a cord 1/4 phone plug.

Actually, this does apply to diversity RX. I have listened on 80M and

price of it by showing the cost of other radios it is being compared to?

I have my K3 loaded with KRX3, KXV3 and KAT3.

Diversity receiving with the K9AY and the main antenna works fine.
I don't want to use ANT2 on the KAT3 for receiving antenna's as I might

I set up the K3 Rx sensitivity test (using 1 microvolt signal) according to

It seems to work in general except that the resulting MDS calculations seem
too low:

130 dBm on 20 meters.
I am using the front headphone jack on the K3,
Could it be a problem with the DMM? If so, is there a recommended DMM?
If using the K3, use the internal RMS audio meter (tap DISP then rotate
until you see AFV).

dynamic range between 400 Hz and 500 Hz is very, very small.

to do but perhaps the following might help:
