Rick, The front view shows the PA board, which confirms that your Micor is a 60 watt, intermittent duty base station, with a non-unified chassis. The repeater version has additional shielding and filtering to permit duplex operation, but many units are able to operate full duplex without them. However, the cover for the PA is missing and should be replaced.
The Micor VHF stations were made in four basic splits: 132-142, 142-150.8, 150.8-162, and 162-174 MHz. Obviously, the 142-150.8 MHz, AKA the "M" split, is the most desired for 2m application, but the most common split found on the surplus market is the 150.8-162 MHz split, AKA the "H" split. There are bandpass filters in the exciter and the PA that are different between the M and H splits, and may need to be replaced or re-tuned to perform optimally on 2m. The RBTIP on this site is a goldmine of information for converting a Micor station to 2m. Although you did state that the station was already set up for 2m, it does happen that a group will simply re-crystal the station and find that it seems to work okay after tuning- but it never performs as well as it could because of these filters. It may be that all of those mods have already been performed, but it never hurts to check! 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Rick Stirling Sent: Saturday, March 18, 2006 12:18 PM To: Rick Stirling; repeater-builder@yahoogroups.com Subject: Re: [Repeater-Builder] Can anyone identify this?
