[Elecraft] KAT500 a good tuner or great tuner

[Gary Gregory]

The kat500 stores information in what are termed 'Bins' and communication
of data via Auxbus recalls memories from these 'Bin' locations and hot
switching does not occur.

I can QSY, with the kpa500 in OPER and 'IF' the kat500 needs to tune it
interrupts the amplifier key line and either selects from memory or does a
tune if in auto etc. I rarely see a need for a retune once I have set up. I
do this regularly as I am on the move touring and so I change antennas to
suit where I am setting up. Wish VK had taller trees in more locations..;-)

I have no issues here that need addressing with regards to operation, QSY
or band changes/hopping etc....

KAT400 #007 might be licenced to kill but evrything has survived my addled
brain and too fast/fat fingers...:-)

73's and Happy Holidays to all.
