Hi Gary;
Look in from with the top off at the RF board where the KAT3 or KANT3
board plugs in.
Check T4 for darkening, it gets cooked if DC is applied to the antenna
connector (like a remote preamp power connected backwards or similar).
You mentioned a remote tuner? Does it get power up the
Hi Gary,
The K3 computes forward and reflected power
from samples taken in the SWR bridge circuit.
A Tif X Gain calibration could fail because the
forward power reading is incorrect due to
a failure in that portion of the SWR bridge
circuit.
Do you have the KAT3 ATU in your K3?
If so, be sure
During operation with a home-brew mag-loop antenna, my K3 (#1222) dropped power
to just under 50W (by the display). There had been an occasional arc in the
external loop tuner, so I'm assuming that was the cause of the K3 failure.
Subsequently, running the 50W TX Gain Calibration, some bands

After the basic checks that Dave and Fred have suggested, if you've not
seen any life I'd quickly check what happens if you turn the power down to
under 10W, this will bypass the KPA3 and if you still see no output then
the problem is deeper into the radio. From here I'd talk to the folks
A couple days ago I encountered that kind of issue: I had the K3 in

as I have run xvtr mode in the past.

Please check the obvious things:
1) Is 'test mode' on?
2) Is the power level turned to zero?
3) Is the VOX on (for CW)?

5) Is your key plugged in/wiring OK?

Bad news here…. My K3 (radio 1) is not transmitting power out.!!

My K3 seems to send out ~50w (1.5:1 SWR) to the antenna. If I connect a dummy
load, ~40w (1.1:1 SWR).Should it send out more RF power or this is what is
expected.? I thought I read it should be something around 90w (?)
Any suggestions.?

Hi Scott,
Check the KPA3 settings in the CONFIG menu
to be sure the 100 watt PA is not bypassed.
If the KPA3 is set to PA NOR in the CONFIG
menu, then you may have a diode failure
in the PIN diode T/R switch or the PA bypass
PIN diode switch.

From the "Troubleshooting" section of the K3 manual:
*No power output*: You may have routed RF through the KXV3’s XVTR IN/OUT
jacks, either by switching
to a transverter band, or by setting CONFIG:KXV3 to TEST. Also try redoing
TX GAIN cal (pg. 49).

Has the rig inadvertently been put into the test mode? If the TX indicator

Have you tried transmitting at 10 watts, and do you get RF output? Do you
also loose receive when you pass the 12 watt threshold? If you have any of
these symptoms, good chance it’s a PIN T/R malfunction.

I had similar trouble related to the synthesizer boards on a K3. On the newer

That sounds to me as though you have the input set for MIC rather than

First I would suggest using Line In and use DATA mode (AFSK A submode),
select Line In in the MIC SEL menu.

I haven't used my K3 in a couple of weeks, but the thought of working
some Au tonight got me going. I turned on the radio, connected the
antenna and I could only get 5 or 6 watts out with the PA and 0.1
watts under the 12W setting. The power didn't vary at all with the
power control, except
into a dummy load with
the ATU bypassed and an indicated SWR of 1.1-1. I'm thinking that one of the
