[Elecraft] KPA1500 Using Multiple Antennas With the Tuner

[Jim McCook]

I followed N4ZR’s thread and did not see a solution.I have the same 
problem as Pete.I’ve got two antennas on 3 bands.I’ve put the tuner 
settings in all the bins on those bands for each each antenna.Neither 
antenna has SWR over 2.5:1.I can then step through the bins with RF on 
each of those bands with ONE antenna with no problem.However, the tuner 
settings were made with 40w.

If I am in a contest and decide to quickly change antennas to call 
someone, the tuner doesn’t recognize the antenna change until RF is 
applied.I apply the same drive power ~30w and before the tuner selects 
the new setting, it sees the mismatch and output jumps to over 1700w, 
high SWR is displayed, and a fault occurs.The only way I can avoid this 
is first go to STBY, apply RF and wait for the new tuner setting to be 
sensed and applied, then go back to OPER.  To go back to the original 
antenna I have to do that all over again. I don’t think this is how it’s 
supposed to be, but I think there must be no solution.How can we go from 
one antenna to another without this problem?73, Jim W6YA
