Is it possible to use the XG3 rather than the XG50 for KX3 setup?
If yes, does the XG3 require a burn-in of similar length?
Also, if yes, after the initial burn-in period, what is the recommended
warm-up time before use as an XG50 substitute?
Thanks, all.

I wonder if anyone has interfaced a K3 with an MFJ-929, used as a remote

One of my antennas is a doublet fed with 450 ohm ladder line. The ideal
place for a tuner is at the base of the ladderline and I intend to
experiment with a variety of baluns to see which work best on which bands.
Both very well built and working as per design. Selling as Ive upgraded to
an XG3 and SARK-110 and also have an 80dB switchable attenuator.
XG2 £45, AT1 £28 + P (P to NA is around £5.50). No problems filling
