Has anyone seen / modified any Wacom Preselector cavities model WP-747L3 / WP-447L1 for use in the 222 / 224 Amateur Band Split?
I have purchased a set of these cavities (they are still in the UPS truck) and I was trying to find any tuning information for them. So far all I can find is some very limited description on the Telwave / Wacom sites for model numbers close to these but not exactly the same. WP-447L2 SPECIAL Preselector 220-222 WP-747L6 TPCP-22612 Preselector, 800 khz BW 220-222 Any specifications or tuning instructions for the WP-747L3 / WP-447L1 cavities or information from anyone that has successfully adapted these cavities as a repeater duplexer in the amateur band would be appreciated.
