I am using the relay contact in the TS-590S, not SG, but the amp us in TX

With nothing but RF in and out connected to the rear panel it goes into TX

Hi Mark
I can relate to what you are experiencing with the KPA500.
You do not mention which rig you are using to drive the KPA500 or how you
have the transmit switching configured.
I bought a new TS590SG some months ago and set it up using the solid state
switching which on the face of it is exa
12.8 is pretty low. I run my Yaesu FP-1030A linear supply at 14.7 V for
K3 and K2. By the time the DC gets to the inside of the K3, it's about
14.5 and higher voltages reduce TX IMD some, not that the K3 isn't
really low IMD to begin with.
Not all power supplies are created equal ... in a ho
Kevin - thanks for the early checkin on 40 meter CW tonight. When I checked in
this afternoon on 20 I was using my K3 and KPA500 at about 450 watts. Tonight
on 40 I fired up the ion-smasher: a SoftRock Ensemble RXTX, running a whopping
1 watt into an 88 foot long doublet at 45 feet.

Hello Bob,
Oh, I would also like to know when the new DSP board (with improved audio) will
be available for K3 upgrade.
As an overseas user, it is better for me to order everything in one-go.

I have not previously run the KAT500 utility, so was unaware of its
capabilities. I have it installed now and I'm studying the facilities.

Apparently yes. However, I'm using the KAT500 serial port to communicate
frequency to the KAT500 via logging software (DXLabs), not auxBus, since the

Do you have the monitor gain up *and* have SPKR+Phones selected in the

the microphone and result in 'squeals'.

What else do you have connected to the K3, specifically the serial port.

Sounds like you may have a strong AM broadcast signal that is
overwhelming the K3 input.
MW signals will be attenuated by the Low Pass Filter, but those signals
below 160m will not be.
The K3 does have some suppression of AM Broadcast band frequencies, but
it may not be sufficient in your case.

The K3 remembers preamp and attenuator status by band. If you want the

NaP3 already includes the ability to set different offsets for CW and CW-R
and those offsets are used in conjunction with the global offset which
applies to all modes. To make it work for the upper bands, you'd need to be
able to specify a separate global offset value based on the band you're on.
