Just in case this ever happens to one of you, here is my salutary tale of how I nearly started ripping my K3 to bits.
I had put a 7Ah SLA battery on my big 13.8V supply just to top it up. This supply not only powers the K3/P3 but also my Samsung monitor, replacing the electrically noisy little psu it came with. I usually turn off the psu when I am neither using the monitor nor the radio. I turned it off and went to bed. Came home from work the next day and noticed the monitor was already on, so just went ahead and used it. Couple of hours later I turned on the K3 but noticed that I was unable to connect to it from Lp-bridge or any other software come to that. Swapped over USB to serial adapters, still the same problem. I thought to myself that there had to be a fault with the RS232 in the K3. Just as I was about to disconnect everything I noticed that the psu was off, I had been running the monitor and then later the K3 off the still connected SLA battery! The K3 was still receiving fine at the reduced voltage (my low voltage is set at 11V), but the 232 port clearly was not. Panic over, but only after an hour of fretting! I must be going senile. 73 Stephen G4SJP -- Sent from Gmail Mobile ______________________________________________________________ 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
