Re: [Elecraft] K3 & Txmon Connection
It acts that way because it IS that way, if the K3 internal tuner is activated. Vic 4X6GP > On 22 Feb 2016, at 2:29 AM, Joel Black wrote: > > Deane, > > I have discovered the same.

Presuming that both of you have the internal tuner in your K3s and no external tuner, then, yes, what you're seeing is expected and normal. Remember that the internal tuner provides a match to the receiver and transmitter but cannot change the complex impedance that is present on the feed line. I do have an external tuner and the TXMON sampling unit is connected between it and the amplifier. I also have an internal tuner on the K3 and sometimes use it instead of the external tuner. When I do, the P3 SWR meter is predictably reading much higher than the radio's SWR meter. 73, Nate N0NB -- "The optimist proclaims that we live in the best of all possible worlds.

Re: [Elecraft] K3 & Txmon Connection
Deane, I have discovered the same. It kind of acts like an SWR meter put *after* a tuner. If I use a resonant antenna or transmit into my dummy load, I don’t get these squirrelly readings. 73, Joel - W4JBB > On Feb 21, 2016, at 6:23 PM, Deane Walkington > wrote: > > I have recently installed the Txmon and have seen some peculiar Power and > SWR readings on the P3 Display.

[Elecraft] K3 & Txmon Connection
I have recently installed the Txmon and have seen some peculiar Power and SWR readings on the P3 Display. Power levels much higher than the K3 is set to and SWR readings much higher (10:1) than the K3 indicates (typically 1.2:1). I connected the Coupler to the K3 ANT 1 socket via a short coax patch cable. What is the preferred method of connecting the Coupler - a UHF male to male adaptor or a short length of coax?At present I have disconnected the coupler from the radio and the P3.
