I do 99% of my K3 band switching with the buttons on the KPA-500, even
if I am not even using the amp, but just have it turned on. It is a
very expensive, effortless band switch!

Hi Charles,
Not a direct answer to your specific amplifier question but something that
might help.
In the last 7 years I don't think I have used the BAND up/down button on my
K3 more than once or perhaps twice. The numbered keypad is easily set up for
each band either directly on the K3 or K3S or by using the K3 Memory Editor
program. Changing bands is then a simple two button process. First press the
M-V button then press one of the ten numbered key buttons. I have button 1
set for 160 meters, 2 for 80 meters........... 0 for 6 meters.
In a similar manner you can then set up each of the four M buttons for band
segments. For example I have M1 set up for the CW portion of the band, M2
for RTTY, M3 for SSB. Again just press M-V then the M button.
And finally, when using a contest or logging program it's very easy to just
type in a frequency on your PC and press enter.

Having no success getting my Flex 6500 to interface with my OM2500A
using ddutil and assorted null modems and serial to USB adapters. Think
of purchasing a K3S since it has a RS232 port that can interface
directly to the OM2500A without the computer/USB adapter/ddutil stuff.
Before making the jump, there are some questions I have about about the
K3S/OM2500A combination:
1. Does anyone out there have a K3S successfully interfaced to a OM2500A
amp using the RS232 post on the K3S?
2. Since the K3S has up/down buttons for band changes, does the OM2500A
reposition the load and tune stepper motors for each band on the way to
the intended band. In other words, on a rapid band change from 80m to
10m, would the OM2500A reposition the tune and load stepper motors for
40M then 30M, then 20M, then 17M, then 15M, then 12M, before
repositioning the stepper motors for 10 meters?
3. If the OM2500A does have to reposition the stepper motors for every
band on the way to the intended band, is there some workaround using the
K3S memories to go directly to the desired band without stepping through
every band on the way to the desired band?
Thanks for the helkp,
Charles K5UA
