As we all know, these are fantastic radios, and well designed and manufactured for long and reliable service. Elecraft has obviously moved its attention - and rightfully so - to their stellar SDR K4 line with every known feature and enhancement you can think of, continuing their superb track record in amateur radio.
However, if you have an older K3 or K3S and are thinking about upgrading or enhancing its performance, perhaps with different filters, sub-receivers, an ATU, transverter, etc., and want help or prefer not to do it yourself, please reach out to me. Happy to provide my services for upgrades/module installation, calibration and troubleshooting and a complete check-out if you want.
These radios are becoming even more valuable as time goes by as they “age well” and can easily remain serviceable for considerably more than a decade-I just upgraded an early S/N K3/100 with ATU, KIO3B, KSYN3A some CW filters and now “almost” like a K3S.
Reach out and I’ll try to help!
