Don't throw them out yet. I was working on a NBFM mod, but just moved and things are all shook up. http://groups.yahoo.com/group/Repeater-Builder/files/FluX%20Research/SEA%20ESP1000%28M%29%2C%20ESP1100%28M%29%2C%20ESP-504/ http://pages.cs.wisc.edu/~timc/e/esp504222.html

Re: [Repeater-Builder] SEA ESP1000 220Mhz Repeater
We acquired a rack of them . All that we found salvageable is the transmitter PA module, power supplies and the chassis. A hamtronics TX and RX with a Cat controller were mounted in the chassis. The filter frame was taken apart and parts were made into a marginal duplexer for 222mhz. We are trying to improve the duplexer, but are at a standstill right now. 73, Joe, K1ike Mike Mullarkey wrote: > > > Looks like it has a nice switching power supply. Welcome to the trash can. > > >

If you do a Google search on them you will find some info on converting them to work on ham freq. In fact the person that did the work on it, is or was at one time a user of this list. Then there is the issue that they are ACSB, so you would need matching radios to use it. Or convert it to FM. This is not a simple mater.

Re: [Repeater-Builder] SEA ESP1000 220Mhz Repeater
Mike, Be careful, they're ACSB not FM. As for programming them into the Ham band, I can't help there. 73, Steve / K6SCA --- On Thu, 7/9/09, Mike Mullarkey wrote: From: Mike Mullarkey Subject: [Repeater-Builder] SEA ESP1000 220Mhz Repeater To: Repeater-Builder@yahoogroups.com Date: Thursday, July 9, 2009, 5:16 PM Ok Guy’s, Got a new one here and looks to be a gem.
