[Elecraft] KXPA 100 Hi Dissipation Fault on 15 Meters

[email]

Ron & Fred,

A few weeks ago, I got help from Mothership Service, confirming that I 
can "reboot" the bricked KPA500 using the utility program.
It worked.  Moral, turn off the back switch of the amp if the USB/serial 
cable is attached.
Trying to find the USB COM port (Linux) for the K4, I inadvertently sent 
a "download data coming" command to the amp.

My YL, gets a chuckle when I find "turn it off and back on", works... as 
we are fans of the "IT Crowd" https://www.youtube.com/watch?v=nn2FB1P_Mn8

73, steve WB3LGC


yes, the KPA500 has been working, like a champ, since the re-load...
