Hello Elecrafter's. My K3/ SN218x have some trbl with the RS232port.
I have my K3 remote controlled by K3/0 mini. via Remoterig. When the K3 is in cold room ( below 5 degrees S) my K3/0 go in TERM mode. Hints say ''replace'' the U1 on the main KIO3 board.......... Is the U1 SN75C1406 ( G4) ? Or can I use similar SN75 ? Removed the top cover,and checked voltage , at gold plated test-point close to the upper edge of the main board +5.0 vdc. In the lower end of the SN75, test point at the left side,seen from the front,, start with approx + 0.35 vdc, and drops slowly to approx -0.50 vdc in 4 to 5 minutes.... My K3 need ''warm up'' also for connecting via PC to K3 utility.... Hits welcome :-) 73' Viggo LA9NEA ______________________________________________________________ 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
