This is a long shot but does anyone want to trade a loaded KX3/PX3 kit
(everything but 2m module) for a KPA500, specifics negotiable of course!
Figured I'd ask before the pain of selling fees etc.! Thanks for looking! Rick

So I'm having the same problem as I've read in a few past posts (with no
resolution). At Approx. 40DegC I lose the signal in the speaker, the S meter
reads no signal, and the F value starts to wildly swing in the 700 range. I'm
directing my hot air at the heatsink for what that's worth. I had
I'm looking for a USB sound "dongle" that will interface with my KX3 for FT8
and similar modes. I have a SignalLink but I'm looking for a more portable
solution. Can someone recommend a current make/model that works well? Thank you.

I just bought one on eBay from "Radiohaus". It is beautiful, high quality, ball
bearings, it spins freely so the torque requirements for a stepping motor are
almost non-existant.

I'm considering purchasing an older KX3 S/N<16xx. From anything I can determine
the encoder was improved and there was a slight change to the 160 and 80 meter
filtering. Oh and the heat sink. Is that it? It appears that there have been
circuit board revs but I can't find any information on what
Not so much interested in the tuner option. Contact me off list to discuss.

Will the KX2 or 3 communicate with a TI through a properly made data cable? I
only see info on mating to a Yeasu rig. Has anyone gotten their KX to talk to a
T1through one of the aux ports? It would be nice to put the T1 at the feedpoint
of an antenna and have it talk to the rig. As it stands
Sorry, this ended up being quite long winded! I'm currently building one from a
Russian Vacuum Variable Cap from ebay. Pure DC resistance is the biggest
challenge as I see it. Even little additional resistance just turns into
useless heat in the loop so R needs to be as low as possible. The MFJ

you try, you will have to answer to the Blue Smoke Monster.

I have one of those MFJ telescoping whips that extends to 1/4 wave on 20 meters

This is a very simple question concerning what is considered mobile or portable

mobile. If I pull over and operate with my mobile setup I am still mobile? If I

I just bought 20' of what was supposed to be 10GA zip wire from that auction

is actually 12GA at best. Is this becoming common practice or is wire going the
way of 2X4 lumber? Suggestions for a reputable source of
OK a very good reality check when you look at the numbers! So I'm still trying
to figure out the usefulness of a built in tuner. Two situations come to mind:
You have no feedline and are driving a wire right out of your rig with a
counterpoise (KX3 portable operations) OR you are using it to
Ok sorry for not providing enough info! Consider this scenario: I have a
portable vertical with 4 counterpoise wires that is resonant on 20. Lets say I
want to tune the antenna up on 40. I can have a tuner right at the base of the
antenna OR I can just use a balun at the base of the antenna
In terms of efficiency, is there a substantial difference between having a
remote tuner at the feedpoint of a vertical vs having a balun at the feedpoint
and the tuner in the rig? Assume a less then 50 ft run of RG58 and at least 4
counterpoise being used in a portable situation with a
Fascinating discussion. Anybody know of any noteworthy books that cover the
subject? Especially tube transmitters and their antennas. Given my love for
Steam trains, breadboard receivers and Ham Radio, I sometimes think I was born

First of all, I'm NOT entertaining purchasing one, I'm happy with my 100W K3.

why one can dial in a bandwidth wider then the installed roofing filter. When I
do so, am I hearing the skirts of the filter and the attenuated signals outside
of the filter's passband as well? Thank you.
Could someone recommend a desktop key that is close to the size and action of
the key attached to the KX3? This Advanced class ham has not sent code in
decades and I would like to start sending on my K3 so can someday use a KX on
