Vern, Yep you got a Micor...a mobile repackaged as a base station.
Might look at the PA. The more transistors the higher the power. The PA came in 45/60/110 W. However, in this configuration if using for repeater turn down to maybe 50% rated power out. This is adjusted with a pot in the Power Control Module, just to the right of the PA. Also add a fan. However, before you get started find what band split it is on. It is VHF (can tell by the 5 inline helicals in the receiver), but need to know segment. As another posting there were 3, 136-150, 150-160 and 160-174. The 160-174 is useless for Ham. Some trouble moving 150-160 down to 146, mainly with receiver. Exciter and PA will most often tune with maybe 10% reduction in power. The power supply is 25 Amp continuous duty Mot used in their 100 W repeaters. Very good power supply for this. 73, ron, n9ee/r >From: [EMAIL PROTECTED] >Date: 2008/03/28 Fri PM 08:01:23 CDT >To: Repeater-Builder@yahoogroups.com >Subject: Re: [Repeater-Builder] Compa Station Help > >How about some pictures?
