Kris, looking at the pictures of the Mitreks of various power levels, I'm not confident there would be holes and heatsink pads in the high-power case that line up with the board mounts and needed contact points of the low-power PA board. But yes - I had considered that approach.
I am completely unfamiliar with the Syntor, cost, availability, etc., but I'm also early in the process of nosing around locally. I'm willing to look at any plentiful, high-quality radios for the conversion. 73, Paul, AE4KR ----- Original Message ----- From: Kris Kirby To: [email protected] Sent: Monday, April 26, 2010 12:26 PM Subject: Re: [Repeater-Builder] Mitreks as UHF Repeaters?

If you do a case swap from a 30W radio into a 100W case, you could be fine for 100%, barring excessive temperature climb. My druthers would be to use an Original Syntor. It's got the helicals of a Mitrek, and the programming of a PROM. At $10 per frequency change (the going rate of the PROM chip), it's still cheaper than the Mitrek and uses the Mitrek/Motrac accessories. -- Kris Kirby, KE4AHR Disinformation Analyst
