I've done some testing. I have a good selection of Times LMR-400-ULTRAFLEX jumpers that I stocked up on from MPD Digital. Never had a problem with any of their cables and so far it's looking like they are all good.
I set things up as Radio <--> KPA500 <--> DL1500 with new cables in between and the KAT500 removed from the chain. Running the radio to 10 watts the radio showed 1.25:1 SWR while the amp was in standby. When in operate, the SWR on the radio maxed out. I fired up KPA500 Remote and bumped the radio up to 20 watts. In standby, radio showing 1.25:1 SWR KPA500 remote reported Power: 18 w (that's typical) SWR: 1.1:1 Current: PTT OFF (typical in standby) Voltage: 74.8 Temp: 22 C Switched the amp to operated, radio still at 20. KPA500 remote reported Power: 0 W SWR: NO RF Current: PTT OFF Voltage: 74.8 Temp: 22 C It's like standby/operate is switching between straight-through and open. It seems to be falling into place with Brian's description of his recent problem. I heard no cracks, booms, or sizzles. Smelled no smoke or ozone. It just started giving me problems intermittently and seems to have finally settled down into a broke state. Working with Elecraft to troubleshoot and will share any findings that might be helpful or garner sympathy. ;) 73, Kev K4VD ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
