K3 + SDR-IQ and regular CW operation

[Bob KD7YZ]

Howdy K3' people:

I was wondering what precautions are taken, or I need to invoke, when I
use any form of transmitting?

At present, the SDR-IQ is connected to the K3's IF BNC. K3's output is
through KAT500 then outside to the antenna some distance away at 80 to
85 feet AGL. Power, while I am testing, is circa 5 to 10 watts.

So I keyed the K3 a few times; called CQ, and so forth. I see my own
trace on the WF of CW-Skimmer, which is set to operate with SDR-IQ as
its "Input" .

Am I golden? Or am I about to overload the K3 and kill it?

thanks

Bob,

You are OK.
There is some bleed-through of the IF output during transmit, and I
believe that is what you are seeing.

I use a mfj t/r switch on te front end of the sdr and see the same thing. Been using for over a year and the sdr seems fine. My sdr is feed by a seperate antenna through the tr sswitch.
