I am enjoying my new KPA500 coupled with my K3, and I have set up the K3 to
transmit at approximately 25 watts in the operate position on all bands
except 30 meters. However, if the amplifier menu is set to default to operate
mode upon KPA500 initialization, I experience an immediate
Let me chime in with an opinion and my reasoning. I have been one of
the vocal ones about having a transverter I/F which it appears will
not be available on the KX3. Understandable; size considerations
make adding that difficult.
But since the KX3 will run 5-10w 160-6m, if one wanted to use
Hi Ed,
The KX3 is intended to provide support for at least one (and maybe
more) external transverters, including a programmable band display and
a keying line. Unlike the K3, there won't be separate transverter IN/
OUT jacks; you'll need to use a transverter with a multiplexed RX/TX
Hi Len
My KPA500 is normally set to PWR ON = STBY, which is the factory default
setting.
But after setting it to OPER for a test, I noticed the same thing.
I suspect this is a timing issue, just like leaving the K3 at low power on
band change if BAND CHG is set to STBY.

Typically zero beat means getting the beat note down to zero, where you

In the days of AM transmission, you'd hear the beat note between the other

Good Day Everyone,
In a recent discussion concering KX3 battery life, Wayne N6KR mentioned:
Transceive operating time from an internal battery will be determined by
voltage or energy-density limitations of the 8 AA cells being used. You'd
probably be transmitting something like 10% of the time
Based on my own experiences in QRP, you need to be sure of what the other
person's callsign is when using less than optimal antennas, so you need to
listen to be sure you have things right; I missed making a contact at lunch a
few weeks ago because I didn't catch the guy's call sign the first
I have seen lots of posts on the filter setup on the K3 with regards to gain
and also changing the filter value entered compared to the value of the filter
itself. I just installed the general coverage unit in the main receiver along
with a 6khz filter. This brought me back to the filter setup
That is no QRP problem, it is important whatever power you run to copy the
other guy's callsign. ;-))

What is the results if you connect the antenna to the K3 (without the
KPA500).
Even though it may show a DC short, that may be only at the DC
measurement. At RF, what is the impedance. An antenna analyzer
measurement may be helpful in determining the actual impedance at frequency.
Have you checked it with an antenna analyzer like an MFJ? That will show where
your setup is resonant. Is the tripod sitting on grass or concrete?? It must
be on grass or dirt to work properly.
