Re: Testing a WACOM WP-678-R2 with a Nanovna-F
You're welcome, Don. One clarification.... The WACOM series of duplexers generally were provided with variable capacitors with enough range to allow the filter to be configured with the notch either

Don't conflate "diplexer" (those solid metal box fixed-filters that let you put a dualband radio with separate VHF/UHF ports to a single dualband antenna or vice-versa) with a "duplexer" (what you're
