Gary,
Good suggestion. I removed the cable going to the antenna switch and now the
K3 and KPA500 appear to talk to one another when changing bands. Pushing a
band button on the amp changes the amp and the K3 to the new band. I still
cannot get the two power levels to work. I also need to figure out how to get
the band switch working with the Y cable.

What bothers me is the amp was not switching bands you said?...If the OPER
switch is set then the aux cable should allow you to switch bands either way
and the amp should indeed switch bands and indicate that on the LCD.
Unfortunately, my FT unit has the original I/O board so I can't verify this
for you...sorry
remove the antenna switch and try see if that makes any difference.

Gary,
No, I did not remove any pins on the cable. This is the one supplied by
Elecraft and I figured that it would be good to go. I just checked the cable
and five pins have been removed. I just removed the Aux Cable from the back of
the KPA500 and now the band buttons work on the amp. So it does appear that
the Aux Cable is the culprit.

Do you have PIN 10 removed on the KPA-500 end of the Y cable?

My KPA500 sn 70 arrived tonight (factory assembled). It took just a
few minutes to hook up and get it on the air. I am using the Y cable on the
ACC port to split off two cables from the K3 ACC port -- one goes to a new
RCS-12 Automatic Antenna Switch and the other goes to the KPA500.
I have AUX BUS on the KPA500 menu turned on and Band Change set to
normal. If I press a band button on the amp, the K3 changes bands and so does
the new antenna switch -- pretty neat. But the band display on the KPA does
not change. I have to hit the key and transmit to get the band to change on
the KPA500. This does not seem correct. It would seem that pressing any on
the band buttons on the amp should change the band on the amp and the frequency
display as well.
Likewise if I change bands on the K3 or via my logging software, the K3
and antenna switch change bands, but the KPA500 does not. I have to tap the
paddle and transmit to get the KPA500 to change to the correct band. I am
wondering if there is a problem with the Aux Cable. Any other suggestions?
I am up to date on firmware for both the K3 and KPA500.
The amp runs very quiet and is silky smooth in full QSK mode. I just
need to get the band changing issue resolved. Any help would be appreciated.
Thank you.
Dave, N4QS
