I’ve just added a new K3EXREF to my K3 but it’s not working. When I select CONFIG->REF CAL, I don’t see the * indicating lock. Also, I can change the cal frequency via VFO A.
I have confirmed that a suitable 10MHz clock is appearing on Pin 8 of the header on the K3EXREF PCB. There is also 49.380MHz presented on pin 6. On pin 1, I can see some very long duration (50ms to 400ms) square waves going from 0 to 4.7v every few seconds. These same pulses appear on Pin 1 of P75 on the KREF3 PCB and then onto the RF board. The K3 is running the latest firmware. Has anyone has similar problems and found a way to fix them? I have put in a call to support but wondering if someone on the list is able to help prior to Monday AM 73 Paul M1CNK ______________________________________________________________ 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
