You should one need one master II. But it will have to modify for full duplex so do this as well as tuning it up completely on a vhf freq first before starting the mods so that you know you are working with a good unit.
I have been a bench tech for years and that mod it not for someone that is new to bench work (I don't say this to be disrespectful or in any way I'm I try to put you down but if you haven't done this type of mod before you may what to find and Elmer to help you please don't take this the wrong way). NHRC make a good controller I have install a few of the 3's and 4's and they work 100%. With a mobile master II you should be able to run up to about 35 watts 100% duty with out a fan and you may ever get by with 50watts with a couple of good fans on the heat sink of the PA. On a master II make sure that you put a 10 ohm 10 watt load resister on the audio output or you will have an oscillation in you rx audio on the same note make sure to not ground either side of the audio output lines it is BTL audio or (floating) Hope this helps if you have more question or what ever fill free to email direct Gary LaForce Chariton Valley TriStar Communications Columbia Service Department Supervisor 573.441.2224 Direct Shop line 573.442.1147 Main Business Line 573.449.8310 Shop Fax line [EMAIL PROTECTED] -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Duane Brantley Sent: Wednesday, April 27, 2005 11:17 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Lookling to build a 220MHz repeater Hello everyone, I recently purchased 4-cavity duplexer for a 220MHZ repeater. I'm thinking about using a GE Mastr II mabile radio for the Rx/Tx part. I'm very green at this and figuring this out on my own. Do I need 2 Mastr II radios, or will one work? I will modify it for 220 service once I know how many I need to get. Also, is the NHRC-3/M2+ a good comtroller for $189? Or is there a better one. This will be a low power repeater . Looking to run 30-50 watts. Thanks for the help, Duane KD5NFQ Yahoo! Groups Links Yahoo!
