RE: [Repeater-Builder] Duplexers F S
The 4 WaCom UHF 10 cavities I believe were designed to be part of a simple duplexer for a UHF-Lo repeater. They *should* tune up to the 440 ham band based on what Telewave has listed for specs on the current modern day model number. Current config is Pass RX Reject TX on 3 cans and Pass TX Reject RX on the 4th can. I'm not a Batlabs member, nor do I care to be (not that I have anything against Batlabs, just suffering from information overload the way it is). Are these pass/reject cavities (I assume they are based on your description above). I'm in need of UHF bandpass cavities. Just straight bandpass, not pass/reject. Preferably quarter-wave rather than 3/4 wave, diameter doesn't matter. Have loads of stuff to trade or cash. Anyone? --- Jeff WN3A

The cavities in this particular case are BpBr.

Hi Jeff, I wouldn't worry about being a member of the Batboard Discussion Forum, it's quite impossible to sign up as the captcha security device (jumbled letters and numbers) is the most fascist I've EVER encountered. There's no way that someone with minor visual impairment could ever sign up to the Batboard; I have uncorrected vision and can't make out 30% of the letter/number combinations (after 6 attempts)... Maybe there's some trick to signing up that I'm not aware of...?!? 73 de Darren G7LWT On 20 February 2010 20:33, Jeff DePolo j...@broadsci.com wrote: The 4 WaCom UHF 10 cavities I believe were designed to be part of a simple duplexer for a UHF-Lo repeater.

Oddly enough, that's my ad ;) Thanks for the bump. The 4 WaCom UHF 10 cavities I believe were designed to be part of a simple duplexer for a UHF-Lo repeater. They *should* tune up to the 440 ham band based on what Telewave has listed for specs on the current modern day model number. Current config is Pass RX Reject TX on 3 cans and Pass TX Reject RX on the 4th can. I would be more than happy to email out specific high res pics to anyone directly off list. 73, AJ On Fri, Feb 19, 2010 at 7:44 PM, motarolla_doctor echoco...@hotmail.comwrote: I ran across this... http://batboard.batlabs.com/viewtopic.php?f=2t=89919
