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,
