[Elecraft] KPA500 & K3 - 30 meters

[David Bunte]

Jim -

I do not yet have a KPA500, but did recently set one up for a friend.
Although the standby/operate function is not remembered on a per band
basis, I am not sure why that might be an issue.

If your concern is that you do not want to inadvertently run 500 watts
on 30 meters, the per band drive level is the perfect solution.  I set
my friend's up so if he is on 40 meters, the drive level of the K3
gives 500 watts out, and when he switched to 30 meters the drive level
drops sufficiently that the KPA500 only puts out 200 watts.  Switching
to standby on any band puts the K3 back to 100 watts.

If your reason is other than the above, I don't know what you need.

I had a KPA500 a year ago and in a moment of stupidity, sold it. Now
considering a replacement. Got a question about it's operation that I
can't for the life of me recall from my previous ownership.

Let's say that I want to use the amp on all the HF bands except for 30
meters. Does the KPA500 have a per-band memory for the "operate /
standby" function? Scenario: If I put the K3/KPA500 on 30 meters and
place the amp in bypass, then drop down to 40 meters and go to
"operate" mode, and then later on go back to 30 meters - will the
KPA500 "remember" that I want it in bypass mode, or do I have to do it
manually? Looked in the downloadable KPA500 manual, but saw no
reference to this.

Thanks in advance, Jim / W6JHB
