I just received a new factory built K3S. It has a weird transmit audio dropout problem.
On 6, 10 & 12 meters, there is a momentary loss of transmit audio every 15 seconds. Occurs with DATA A, SSB modes. CW is clean. Problem occurs with internal or external sound card and even with the built-in 2 tone test. The audio dropout is repeatable and precisely formed as two 10 ms dropouts separated by 15 ms and the pattern repeats every 15 seconds. Been working with Elecraft support for 3 days, but they are running out of ideas. It really looks like a firmware bug given that the timing and waveform characteristics are 100% repeatable and lack any randomness factor. But, why just on the three upper bands? Why are those bands unique? (besides the incorporation of Preamp 2). Has anyone else seen this? Any ideas? ________ 73, Jim - N4ST ______________________________________________________________ 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 Message delivered to [email protected]
