Re: 6 m repeater antenna
Chill out Chris.

Re: WTB: 107.2 Hz Vibrasender
The KLN6209 or a TLN6824 will also work.
The TLN6824 is common as it was the Micor encode reed.

Re: Icom FR4000-3 Repeater
I've had some progress tonight. Two simple mistakes I should have avoided.

Re: WACOM WP-641 vs. Sinclair Q2330E
The WACOM WP-641 provides 93 dB of rejection at 1.5dB of insertion loss at 600 kHz - if it's a UHF connector version.? If it's an N connector version the rejection is 91 dB or so (yes it's less).?
