Brian, as I recall after extensive field testing and from experience, losing power can cause issues with the current required state. I would suggest using a battery backup for critical components. I use a Rig Runner device to keep a marine battery charged and a power supply for just such issues. Good luck.

I have a remote that uses a KAT500 that is now 3000 miles away. The KAT500 was calibrated to use the correct antenna over all bands 160 to 6 meters at the specified increments (10 KHz 160 etc and 20 KHz for the higher bands) For an unknown reason the KAT 500 has switched to antenna 2 (160 and 80) for all frequencies. Unfortunately I did not connect the USB cable because I could not see recalibrating the kAT500 remotely . The remote is now shut down until I can persuade my daughter who lives 60 miles from the station to add a USB cable I will have to have shipped to her. 73 Brian KF6C ______________________________________________________________ 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 k9...@live.com ______________________________________________________________ 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
