Re: [Repeater-Builder] FCC considers Auxiliary Operation on 2M!
Hmmm... using that logic, you can have the most reliable repeater by not putting it on the air at all. That way, it will last forever. :-) (provided it's not using tubes) Actually, I would tend to think that like us, periodic exercise isn't a bad thing for a repeater. It will help keep the caps trim and the transistors fit. Although I admittedly don't have any proof for that theory. Joe M.

This is an asenine statement,if the repeater is in heavy use,you know for sure that its in good working order,you have a pool of available operators and it will probably handle anything you can throw at it. You cannot go thru life wearing blinders,the repeater serves many roles,including drive time chit-chat,late night bs sessions and emergency traffic.

I am looking for a program for Win XP that will run like wintone. I like wintone layout, line by line, but I cant seem to get it to read instantly, it takes 2 seconds to start at every transmission. Is there a program that will do the same and is free. The audio will come from the line-in on the sound card. Thanks in advance for your help, Mike Also, is there a MDC1200 decoding program too?

Ed, You have nailed it exactly. It's a classic case. Circulators on each transmitter should help but any rusty bolt, moisture, or loose hardware near the antennas can contribute to the problem. This is not a good frequency pairing and will always be giving problems. 73, Al, K9SI Date: Sun, 18 Apr 2004 11:44:06 -0700 From: Ed Yoho [EMAIL PROTECTED] Subject: Re: Re: Is there a relationship between 147.225 and 146.925?

Re: [Repeater-Builder] Digest Number 2472
The individual elements on a Signals array are each 50 ohms. Those elements have a larger diameter element where the feedline attaches, (up to the bend). I've tested those and can confirm. However, I've never tested one of the single Decibel elements. Now, please keep in mind that I am talking about the UHF antennas. A single element on a VHF low band Decibel folded dipole is 50 ohms.

Feed the test antenna element with an even multiple of a half wavelength of the coax you prefer. Make sure the element is set up in a typical operating environment, that is, mounted on its mast and preferably the mast clamped to the side of a tower or another chunk of iron similar to a tower. You can do this with the element at eye level just to get an idea of how it operates. Not a precision set-up but, true, but will get you in the ball park. Yours may be 100 ohms but all the folded-dipole types I ever played with were close to 50. 73 Al, K9SI Date: Sat, 17 Apr 2004 22:25:06 -0400 From: Chuck Kelsey [EMAIL PROTECTED] Subject: Re: Re: Decibel repeater antenna question..

The transmit frequency is still about 1 meg away from the receive frequency of the other repeater. How far apart in frequency would they ahve to be to co exist while running relatively low power? It's not how far apart they are - it's the math associated between them. The mixing products are killing you, not the signal strength. You can have a 5 MHz TX and a 440 MHz TX mix and end up with a product (3A-2B) on the 440 input, and those are 435 MHz apart! I don't know how the guy in Colorado put on 440 repeaters with WWV so close out there. Similarly, 600 kHz signals are bad for 2M repeaters, 1.6 MHz signals are bad for 220, just about everything is bad for 6M depending on where you live ;-, Etc. I don't think a different frequency will be possible since all seem to be taken. Another location is always a drag as well. It may be a drag, but may be the easiest solution. One case in my area had two repeaters that are about 20 miles apart had a very similar problem. I think the frequency outputs were 146.670 and 147.270 MHz. Again, 2B-1A was killing them.

Re: [Repeater-Builder] Receiver Sensitivity
If the value for Receiver B is also based upon a 12dB SINAD, yes, Receiver A is more sensitive.
