Gentlemen I am brainstorming about constructing a portable - temp use - Pelican Case portable 2m repeater using the 6 meter Heliax duplexer concept.
I had built a 6m duplexer for .5 mhz split using this method 12 years ago and it worked quite well. I have built a single cavity 2m notch filter for APRS use, so I believe the concept can work. Has anybody tried building a 2m duplexer using this method that would do a 600khz split? Advice, suggestions? 73 Ed N3SDO
