I did something tonight I have not done before since having my P3 TX Monitor in
place. I was testing the adjustment on my paddle in TX Test Mode and I noticed
that the P3 acted as normal — that is, no signal — with the exception of the
bar graph for SWR. The bar graph registered an SWR of 3:1
To answer a few questions, I'll try to be as definitive as possible.
I see, according to both the P3 TX Mon AND the LP-100A up to about 0.4
watts output from the K3S on CW mode in TEST. The sensors for both the
TX Mon and the LP-100A are in series, the TX Mon immediately after the
K3S and the
Mine registers anything it wants in non transmit mode, many times pegs
the swr chart, other
times 2 or 3 to 1.. normal from what I see.

Phil:
Do you have a K3S by any chance. My K3S actually transmits a signal
when in TEST mode! When I told Elecraft about it, they shrugged their
heads like it can't be.
The TX power appears both on my P3 (with TX MON showing both PEP and
SWR), and also my LP-100A wattmeter. It's only very,
At what power level do you see or measure this signal? I don't seem to
see any power output in TEST mode during transmit.

In Test mode there is no signal output at all. That is the reason for Test
Mode. So, on the P3, you don’t see a signal and you don’t see signal power
level. But, the fact that the SWR bar chart shows something is, to me, an
anomaly.

OK Phil. I supposed I was confused where you said " My K3S actually
transmits a signal when in TEST mode!" I didn't find any measurable
output when in TEST mode using my K3S.
Thanks.

Actually, I don’t have a K3S. Though, I do see another message quoted below
from Dan Atchison who mentions a K3S transmitting a signal in Test mode. No
signal on a K3 though.

If I had to guess, which is exactly what I'm doing, I think either the LPA or
the HPA is generating a spurious signal and it sees a mismatch into your BPF. I
would try to get it into this state and use your other radio to sniff around.

Dan,
This is very odd behavior. There should be no output in TEST mode, and no
contribution to SWR from the KAT3A. The two problems may be related.
I hope you can return the rig to us for analysis. It will of course be covered
under warranty.

I notice this too with my K3and TXMon. It appears to occur in the Test
Mode after I've previously used the transmitter. My guess is that there
may be a capacitor or two holding some voltagefrom the prior real
transmission. If I use the test mode first, before any transmissions,

If no valid result is possible, then "1:1" would be the *worst* possible
choice! Simply blank the display or show "N/A".
Most QRPers understand that primitive SWR meters
