Hi Bob, It really sounds like a menu setting has been changed. Take a look at this:
When driving the KPA500 with an Elecraft K3, use the K3’s per-band power control to set the amplifier output just below the desired peak output on each band. Do not rely on ALC to control the power output (see Using ALC, pg 17). At the K3, set CONFIG:POWER SET to Per Band. See Per-Band Power Control in your K3 Owner’s manual for further details. If you use the AUX cable interface between the K3 and KPA500 (pg 26), the KPA500 will send the OPER/STBY status to the K3. You can then set two per-band power levels at the K3: one to drive the KPA500 when it is in OPER mode and another for pass-through transmitting when the KPA500 is in STBY. The K3 will automatically furnish your preset power levels as you switch the KPA500 between OPER and STBY. 73 de Jim - KE8G ---- Chortek Bob via Elecraft <[email protected]> wrote: > Hi Scott, I have the same problem and have not been able to solve it.... It worked perfectly for a few days and then it developed the symptoms you described - plus the auto power select stopped working on the K3 (rig no longer goes from high power to low power when the KPA500 is enabled). I will see what suggestions you get. I may need to send both back to Elecraft to have them look over the equipment. 73, Bob/AA6VB From: NE9U - Jasper <[email protected]> To: "[email protected]" <[email protected]> Sent: Friday, October 30, 2015 10:23 PM Subject: [Elecraft] kpa500 doesnt follow k3 Just hooked a new kpa500 to a k3. when switching bands on the k3, the kpa500 doesnt follow. it does follow when i apply power. the reverse does work....if i switch bands on the kpa500, the k3 follows. tried 2 different auxillary cables...same result with both. am i missing some setting i need to change? scott ne9u Sent from Republic Wireless Cray-1 ______________________________________________________________ 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] ______________________________________________________________ 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] ______________________________________________________________ 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]
