1. Does anyone out there have a K3S successfully interfaced to a
OM2500A amp using the RS232 post on the K3S?
I'm using OM-Power amp with K3 (not "S").
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?
The amplifier does NOT re-tune for band changes until you tap the key or
PTT.
You must connect the TX inhibit line between K3 and amplifier. When you
change bands on K3, OM Power asserts the TX inhibit line to prevent K3
from transmitting. Once you tap PTT/VOX/key, the amp tunes and releases
TX inhibit.
