Here's a thought -- why not fill out the K-line with an S-line-like

Of course, the K3 really wants to have two speakers -- especially if a sub

Thanks to several who replied and it was really great news to learn Tom is
OK. He sent me a note yesterday and said he hopes to be released from the

prayers for a speedy and complete recovery.

Kind of hard to beat an Astron 35 for power and a pair of Behringer MS40
speakers for audio. Sure, they don't match - but they work well.

Please be advised that Astron supplies are generally

My k3 comes with K144XV internal 2m transverter. I seldom used it in the
past. However, in my recent operation, I notice a strange behaviour. There

I have an RS-20 but use an RS-35M dedicated to my K3. I have it and my

affecting the radio.
I leave both the UPS and RS-35M on and turn off the K3 with the front panel

Lowering the gain to 5 is about right. I often have the external speakers on,

How old is your radio? Isn't there an Elecraft mod for that?
