I have a friend across town who has a KPA500 built from a kit Aug 2017 SN 33XX who has never used his K3S or KPA500 on17 m and just got an antenna for 17 and lo and behold NOTHING he does will allow operation on 17.
He normally always used the Utility to change bands etc .So he took that RS232 cable off off and used the KPAK3AUX cable between the K3S and its switching between ALL bands following the K3S band but on17M the KPA500 SWR is OK in bypass but is high SWR in OPR and the K3S detects itand will just show high SWR. The K3S will put out power in STBY but of course not in KPA500 OPER because of the SWR. He has checked with his VNA and in fact the path thru the KPA is is essentially open on17 and in OPR and OK in STBY (50 ohm dummy load) . He tried cycling the bands many times thinking maybe the 17 M LPF relays were not making good contact since he had never tried 17M .No joy. He installed the latest firmware today and no change. So has anyone seen this ?? Archive search so far shows people have had 17 M issues but for other reasons. He plans to open it up and look at the LPF filter test port later if no ideas.
