[Elecraft] KAT500 and VARA

[Andy Durbin]

The KAT500 used to have two annoying behaviors associated with RF count frequency:


  1.
Tune could be initiated in the current "bin".  This is prevented by operating in MAN mode.
  2.
The tuner could jump to an adjacent bin and select a different tuning solution.  This cannot be prevented by operating in MAN mode.

For a long time Elecraft insisted that RF count would always take priority over any other frequency.  That has changed.  Give the KAT500 a stable transceiver TX frequency using AUX bus or RS-232.  Then disable RF count using FDT as described earlier by Dick, K6KR.  All retune and bin jumping will be eliminated.

Note the requirement to give the KAT500 the TX frequency.  If the KAT500 is given rig dial frequency it may still jump to a different bin when TX starts if operating split.
