Has anyone Interfaced a K3S and OM2500A
Locked
 
|
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?

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. 73, Josh W6XU ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

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. 73, Mike K2MK

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! 73, George, K5KG On 10/31/2015 2:45 PM, Mike K2MK wrote: > 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.
