Re: [Repeater-Builder] DB-4001

[Dave Baughn]

Yes, I have re-tuned a couple to 144.75. Loops work fine with no mod. You can add a trimmer cap in series with the loop and convert to BP/BR. There is a lot of info one how to do that on the repeater-builder web site.   Dave Baughn Director of Engineering The University of Alabama Center for Public Television and Radio WVUA/WUOA-TV & WUAL/ WQPR/ WAPR FM Box 870150 195 Reese Phifer Hall, 901 University Blvd. Tuscaloosa, Alabama 35487 205.348.8622 cell 205.310.8798 NEW EMAIL [EMAIL PROTECTED] >>> "jrhobart" <[EMAIL PROTECTED]> 5/6/2007 4:53 PM >>> Will Decibel DB-4001 cavities tune to 146.0 MHz? Would the coupling loops need to be lengthened? Is this practical? Would three DB-4001 bandpass and three similar looking notch (I assume due to only one UHF connector) cavities make a good duplexer? Pitfalls? Thanks, Joe, W7LUX
