    Phil, have you had the chance to check out the TAPR/Ten-Tec VNA? I
bought one, but I have not tried it on an AM station yet. < $ 700,
plus a laptop. I get some really cool smith charts on my ham antennas
(impresses the other guys at the ham club meetings, not that I know
what anything means!) I do not know if this unit is precise enough for
broadcast use, although they supply precise terminations to calibrate
it. The power level might be on the low side for some sites though.
