You are talking about Line-out of the K3.
First question is: is it working ok with your headset on? So can you
hear the subRX that way?
If that is working as it should then do the next check:

Thanks Sam but that isn't it. I get the Sub RX audio just fine in the

What I am missing is the Sub Rx on the right channel of the Line Out

Hello everybody!
Ever since i got my new P3 - i've been looking at people's signals (naturally).
And i've noticed the following:
When using USB on 10 meters, talking locally, there are a couple of folks that
use ICOM radios and i can see these spikes on the left of the carrier.

I have also noticed this, is the robotic sound you are referring to a

The new K3/0 mini is like an outsized KX3 . It shares the front panel of

Where (how) are you connecting between the K3 and MK II?
You should use a the stereo audio cable supplied with MK II to connect

cable set to the Sub RX jack on the back of MK II.
Sub RX audio is present *only* when the SUB
A spike on the left of a USB signal is normally an indication of
insufficient carrier suppression (carrier leakage). Signal to the
left of that is generally insufficient opposite sideband suppression
(sideband leakage) or regenerated sideband due to excess IMD in the
transmitter.
However, if
Hello Rick,
I trust you will get advice from experienced builders here. Here are some
additional points, you may wish to consider:
1. If you do not need a one-piece K2/100, you may wish to think about a
KXPA100 instead. KXPA100 can work with any QRP transceiver including K2.
2. There is a

If you're interested in running 100 watts I highly

Joe - that is what I have set up. If I turn on the Sub Rx and plug a
