I just finished building my KAT500 and KPA500. I am trying to integrate them into my existing setup consisting of a K3, P3, and Microham Microkeyer II. This setup was working fine before I cabled up the new equipment, and now I am having some issues. All hardware has been updated to the latest available firmware. I have cabled the equipment as follows (as prescribed in the KAT500 manual, with the addition of the Elecraft Y-Cable so the KAT500 and MKII can access the ACC port on the K3): KAT500:- ANT1 -> HexBeam feed- XMTR -> KPA500 RF OUTPUT- XCVR -> E850463 Aux Cable -> Elecraft Y-Cable -> K3 ACC (shares ACC w/microHam MicroKeyer II)- AMP -> E8509463 Aux Cable -> KPA500 AUX- VDC -> AC to DC 15V 1000 mA adapter
KPA500:- RF OUTPUT -> KAT500 XMTR- AUX -> KAT500 AMP MicroKeyer II - ACC -> Elecraft Y-Cable -> K3 ACC K3:- ANT1 -> KPA500 RF INPUT - I have set the KAT3 CONFIG menu to Bypass.- I enabled KAT500Y by tapping 1 on the KAT3 CONFIG menu.- KAT500 is in AUTO mode- Tuning power is set to 25W - Power is set to PER BAND- I have used the KAT500 to memorize settings at the low, high, and midpoints of the bands I operate, and I selected the "Optimize for KPA500" setting in the KAT500 Utility program. And the problems I am observing so far are: - The KPA500 isn't talking to the K3 (or vice versa); band changes are not being tracked from either device- The KPA500 isn't amplifying any amount of drive (at 35 watts out of the K3, the first LED on the KPA500 lights. Even with the OPER LED lit).- The KAT500 doesn't always power on. Sometimes the K3 has to be on first. Reconnecting the ACC port on the K3 seems to trigger this state.- The K3 isn't responding to mode changes in WinWarbler (RTTY/CW/SSB) Something tells me I've got a problem with the ACC line and or cabling. Thanks for any help you guys can provide!Jeff ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
