I do not have my K3 yet. I have been reading about it.
I would like to use it with an Ameritron AL82 in semi QSK (vox on).
I do not see an amp connection mentioned in the manual
What is the hook up for a non QSK amp to the K3?
Tks very much
Gerry
Gerry,
As with any amplifier ---
Connect the K3 output coax to the AL82 input coax, and connect the K3
KEYOUT to the AL82 PTT IN (or whatever they call it).
Forget the ALC cable - instead, adjust the K3 power output to drive the
AL82 to its full output (or whatever you want below that level),
Change training below to trailing

In other words, semi QSK controls the training edge of the KEYOUT
signal, but does not change the leading edge. TX DLY will control the
leading edge up to the limit of its range.

they could easily make the modification in the firmware. If they decide to
respond to this issue and say they won't or can't do it then I'll be glad to
look for a hardware modification to my amp.

I've got a K3 on order, and I'm not worried at all about
timing issues switching my amplifier. I use a microHam
CW keyer to key all my rigs. The cw keyer uses the K1EL
chip that puts out a PTT signal (for keying an amplifier) with programmable
lead-in and tail times with respect to

10msec or longer is unreasonably slow and I think it's 'unreasonable' to
blame the manufacturer of the radio because the amp manufacturer saved a
few bucks and used a cheap, slow relay instead

Bob speaks the truth here. The K6XX fast relay circuit
is the answer.

My K3 #339 went QRV yesterday afternoon after successfully
downloading firmware via the upgraded Mac utility. The previous
version of the utility, which I had downloaded weeks ago in
anticipation, did not allow for successful DSP firmware download.
With the new utility it was a breeze.

Hi Tod,
One question remains and it is probably ridiculously simple but I can
not see it. How do I get the K3 to trigger the relay in my Ameritron AL
1200?. I see no connection for a cable to the amp nor nothing in the
config menu.
I don't know the Ameritron AL but KEY OUT should be what you
The KEY OUT RCA jack on the back of the K3 will key the amp.

If you're 20 over in Europe, you don't need an amp!! :-)

Beware the manual for the AL1200 doesn't appear to mention the change
over timing of it's relay, the K3 outputs RF approx 10 milli seconds
after the linear keying line goes low - measured on mine with a half
decent scope. There is currently no adjustable delay for that timing in
the K3
Todd -
KEY OUT on the back of the K3 is for connecting to an external amp.

putting a slow relay in the keying circuit which I need anyway to invert the

I am using my K3 with an AL80A...basic amp with the same relay as many of the
other Amertrons use. I have seen no issues at all. Also, you might look at
