Neil, Maybe, I thought it was on Cedar Hill with the rest of the TV transmitters. Guess I will have to research that, I am a little closer to that transmitter than the Cedar Hill sites, hope it does not affect me too much.

RE: [Repeater-Builder] Re: 6 meter repeater duplexer (not used)
Yeah, when Mobilecomm (now Arch) decomissioned their 30 and 40 MHz paging systems here on the east coast, lowband Decibel and Celwave pass cavities were a dime a dozen (or often free). I scooped up as many as I could store, probably 50 or so. All but a few are in service on 6m repeaters, most of which were converted to pass/reject and used to make duplexers. Every now and then I still see them pop up at hamfests, but not like it was 6 or 7 years ago. There was a guy that used to be on this list (K4YC?) who drove up from George and hauled away all the lower-frequency cavities I had since I was out of storage space, probably 20 or more of them. Now that my supply is starting to run out I'm wishing I hadn't given them all away; they could have been cut down to 6m. Maybe he's still lurking? --- Jeff > -Original Message- > From: Repeater-Builder@yahoogroups.com > [mailto:[EMAIL PROTECTED] On Behalf Of skipp025 > Sent: Sunday, November 27, 2005 12:58 PM > To: Repeater-Builder@yahoogroups.com > Subject: [Repeater-Builder] Re: 6 meter repeater duplexer (not used) > > > Before Ebay came on line... people were giving away low > band cavities at the flea markets.

True ... Before 6 meter repeaters became really popular in Oregon - last several years - DB Products 40-50 MHz cans were going for $25 or $50 at the local swapmeets.
