I think you can only hear Main Rec VFO A or VFO B. The only way to hear VFO A
and VFO B at the same time is with KRX3 sub-receiver as VFO B.

Hi Dick,
I would be interested in participating. Using a Flex 6700 via the KXUSB
cable from amp direct to USB port on radio. Set up to track the TX slice on
radio. Been working fine. Flex has a setting to auto poll.
I also have written a flow for Node Red to monitor and control the amp via a

I've made some recent changes to KPA1500 processing of transceiver frequency
messages from Kenwood, Flex, and Yaesu radios. Icom CI-V is unchanged.
If you use one of these radios and use the KPA1500's XCVR SERIAL connection
to communicate the transceiver's frequency to the KPA1500, I'd appreci
That is why just looking for loose TMP connectors may not be sufficient.
While you are inside the K3, give all the TMP connectors a slight twist
which should clear some of the corrosion.

You need to set the "SPKRS" on the Config menu to "1" in order to hear them
both at once.

The same problem, exactly, that could be solved only changing the switch and
the annex internal cabling.
You should require it to Elecraft.
It need 20 minutes becouse the speaker must be largely disassembled for
changing this part.

Hi Per-Tore,
I don't know if there's an easy way to check the PIN diodes in the T/R
switch, especially since the SMD components of the switch are mostly on the
underside of the RF board. Here's where I would start:
1) Find spots on the RF board (top side) where you can measure the control

Apologies, I just saw the serial number 7818, quite a bit newer so
maybe not a failed capacitor, yet :)

Hi,
What Serial number?
I have found on my own and a friends K3, both very low S/N around 300,
that the KREF3 board has been the culprit for this exact problem.
First check the all the TMP cables to and from the KREF3 board and the
synths. If all look good you should examine the K3REF board.

Thanks, Mike.
I guess this is the MA4P PIN diodes D26 & D27.
Is there an easy way to check those?

You might check the PIN diode T/R switch. The high attenuation in RX mode
and no output power even when the 100 W PA is bypassed suggest that one or
more of the PIN diodes in the T/R switch have failed "open."

Yes, all bands are the same.
Received signals are normal in all respects, except signal strength.

Would not that make the rx dead?
I can hear strong signals.
But the tx is giving no output.

After 6 months off the air, I find myself confused by the K3's audio

While I'm able to hear the Main A VFO and Sub RX VFO through my one

VFOs through that speaker.
Is there a way to configure this, or do
