I had this happen when I got my KPA-1500 a few years ago. When using my old
IC-7000 it was fine, using 100W from my K3s was good but QRO, at any level,
and it went to heck. I was advised by several folks that the matching
network on my antenna (M-Squared 6M5) was known to be problematic at high

So I did a bit of measuring today. It looks like I only need somewhere around
10 to 13 feet of DE15 extension. Digi-Key sells the 15’ version for $21 (plus
shipping). A bit spendy, but if it keeps the amp far away from the shack I’ll
be happy…and so will the XYL . Getting the molded plug downsta
I actually have a currently-unused run of network cable that will reach the amp
when it's relocated, on a home run from the main gigabit switch. It's how I
used to feed my old weather station Windows PC before I went to an RPi about 6
or 7 years ago. I can't tell you the last time that computer

Not sure what you mean by “set drive power” this is something I generally do
manually, but would love the ability to do it automatically based on band
segment. 40m SSB is a problem child for me where a short Yagi means I have to
cut back drive power above 7175 or so due to SWR. I do not want to

I hadn't considered that! Is there a preferred way of doing this over longer
distances? I'm sure I'm not the only person who's needed to remote the amp.

I need to move my KPA-1500 into the basement, and I've got an electrician
coming to put in the new outlet next week. But the only tricky issue now is
finding the correct cable to run to the amp from my Y-Box to provide
frequency/band data, etc. I will need a cable run of about 20 feet, which

Didn't hit the off button by mistake, but the radio shuts itself off when I

Exact same thing happened to my K3s in October, now my KPA-1500. Yeah, So
done here. Once repaired and confirmed working it will be up for sale. Going
back to a tube amp after this.

I was operating in the ARRL-CW contest this morning and on 20m, with a 1.2:1
SWR on the Yagi, all of a sudden I saw my power drop to about 450-500W with
about 40W in. Worked a few stations but not as easily as when I turned
everything on this morning. Switched over to phone and made a few contacts.
Hi All
I don't like re-inventing the wheel, so I'm looking for a design to
copy!
I'm looking for a circuit to interlock two K3 so they cannot transmit
simultaneously. I am aware of the simple connection cross linking the
PTT out and Inbibit input on the 15 pin connector. That does not meet
