My old K3 (serial #80) with dual RX and KSYN3A upgrade synths, has developed a fault.
A “tune up” carrier, CW transmission, AM transmission, all exhibit 100Hz “modulation” with spurious carriers every 100Hz each side of the centre frequency. They start around 10dB down and drop off in a similar manner to SSB IMD products. Receive sounds fine. The issue is not always present when the K3 is cold, it is not related to external connections (removed all except power), nor to a power supply (swapped it and the power lead). It is also present on low power and on all bands. I’ve asked Elecraft Support, no reply so far. Any ideas as to what might be the problem?
