[Elecraft] RS-232 communication failure KPA100
My PC to KPA100 communication suddenly failed. Checked the cabling and did some initial tracing from J1 to U4. Seems ok incl. RFC:s. I found deviating voltages on U4 pins: 2 -5,5 3 -10,7 4,5,6 -5,5 7,8 -10,7 with remaining U4 pin readings ok. Then tried to find the 16293 kHz signal on my SW receiver but couldn´t hear it. I however find -75 V at the end of the diode chain.so is the HV xtal oscillator at fault or not? Any suggestion on what to do next is much appreciated! Thanks, 73, Per SM0WRA .

[Elecraft] RS-232 communication failure
Från: Per Enocson [mailto:[EMAIL PROTECTED] Skickat: den 29 augusti 2006 22:28 Till: [EMAIL PROTECTED] Ämne: SV: [Elecraft] RS-232 communication failure Hi Mark, Yes, you have a valid point and I have only used cables as described in the KPA-100 manual.The set up worked flawlessly during four years and, mystery, all of sudden, communication breakdown! I am currently measuring all voltages in the RS-232 interface part of the amp and suspect hardware failure (defect U4 MAX 1406??)as some voltages are out of range. 73 Per SM0WRA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] RS-232 communication failure
Remember, the KIO2 does not use an RS-232 cable! The KIO2 requires a special cable for computer control.
