Re: [Elecraft] KX3 Opposite Sideband Null -- Follow Up

Hi,I got several error codes on my KX3 about a year ago. I sent it back for repairs and upgrades as it is 0250+ s/n. Most error codes were cause by the defective ribbon cable between the front and rear boards. One code was a cracked resistor on the KXFL3. Repairs were done quick and got a

[Elecraft] KX3 Opposite Sideband Null -- Follow Up

Six weeks or so ago, I put up a couple of posts asking if anyone had had an issue with opposite sideband null on their KX3. I was having a problem getting a good null when FL3 was selected, although I had very deep nulls with FL2 or FL1. I wasn’t motivated to check because of a perceived

Re: [Elecraft] Matching resonant antennas

Lyn, How do you measure your antenna's performance? In many cases, not necessarily yours, antenna performance seems to be based on countries worked, achieving WAS/DXCC, "It's way better than last year's antenna.", or "I worked Pitcarin Island last week." None of these "measures" are meaningful.
