Kevin,
Any suggestions for a decent quality 220mhz amp for repeater duty? Micor 20-25 watts drive or pull the PA and exciter in and 50-60 watts output?

If so what works and what doesnt. I need several 225 radios and thought this might be a route to go. I have converted MASTR II Mobiles, both multiplier and PLL exciter, with standard receivers to 220 MHz. - they work fine, the PLL is easier. There are preferred instructions on the MASTR II conversion site: http://www.repeater-builder.com/rbtip/geindex.html#220 <http://www.repeater-builder.com/rbtip/geindex.html#220> For the M2 with a PLL exciter, Scott sells a complete conversion kit: http://www.repeater-builder.com/products/MIIconversionkit.html <http://www.repeater-builder.com/products/MIIconversionkit.html> The PA's won't convert, but there is an easy fix: http://www.repeater-builder.com/products/ampbd.html <http://www.repeater-builder.com/products/ampbd.html> I have converted MICOR Mobiles and Stations to 220 MHz. - they also work fine. There are preferred instructions on the MICOR conversion site: http://www.repeater-builder.com/rbtip/micor-index.html#220 <http://www.repeater-builder.com/rbtip/micor-index.html#220> Helical Resonators modified for 220 operation are available here: http://www.repeater-builder.com/products/ <http://www.repeater-builder.com/products/> The PA's won't convert, but again - never fear, the amp board is the solution: http://www.repeater-builder.com/products/ampbd.html <http://www.repeater-builder.com/products/ampbd.html> Any of the above radios can be converted to 220 MHz and achieve book specification sensitivity on the new band. My favorite is the MICOR. Hope this helps... Kevin Custer
