Re: [Repeater-Builder] Repeater heard on Aviation Channel! HELP

Hey Mathew I know it must be frustrating for you but you know there is something you could be doing to help Dave out.   1) Track the times it does this. Look for a pattern.   2) Record the temperature at the site, especially when it acts up. Both inside and outside temp and is the sun shinning on the antenna when it acts up.   3) Make a list of all Xmitters in a 15 mile range with frequency.   4) Note if this problem only shows up with one user or all users.  Or do they have to be in a certain location for it to happen.   5) Make note what your old antenna was when you didn't have the problem vs. the new one and did you use a new connector for it?  This checks to see if the antenna pattern has changed.   6) This maybe out in left field but is anybody playing with BPL in the area?   7) Nominal voltages on you supply when it doesn't act up and what they are when it does act up.   I can't think of anything else but I'm sure other people on the list will have some ideas to add also.  Intermitant problems like this can be the hardest thing to track down so all info you can gather will help Dave.   73, Mike, K1EG   ----- Original Message ----- From: Mathew Quaife To: Repeater-Builder@yahoogroups.com Sent: Friday, July 08, 2005 6:19 PM Subject: Re: [Repeater-Builder] Repeater heard on Aviation Channel! HELP Well I think with Dave's knowledge and equipment, he might be able to see what is going on.  I'm certain he will find a number of my mistakes as I call them.  I'm a tinker with a dangerous plan.  I've talked with the EE Spectrum engineer at the aviation department, he seems to think I am riding along something as well, another frequency or something nearby.  Hopefully there is an easy answer for it.   Mathew Bob Dengler <[EMAIL PROTECTED]> wrote: At 7/8/2005 12:21 PM, you wrote: >Best bring the biggest hammer that you have.

This is standard procedure for me anytime an intermittent spurious/noise problem shows up. It's also standard procedure for all my comm site installations. Bob NO6B Yahoo!
