Re: [Repeater-Builder] duplexer tuning question
If these are like my TX/RX duplexers, the slighest movement of the tuning rods makes a huge difference, especially on the tx side. retune would be a good idea. Take them slow, they are fun to tune.

[Repeater-Builder] Re: dtmf, ctcss and pl decoding
There is a simple algorithm which can be used to detect DTMF or PL tones. I believe the name is the Goertzel method. Basically it consists of multiplying the expected tone frequencies with the incoming audio. These frequencies come from a lookup table that you create. The idea is that then you low pass filter the result (integrate) and a tone near the desired frequency creates DC or a low frequency beat that can be detected. I have built working versions of this for touch tone detection. The processing used up all of the speed in a 4MHz 8 bit 6805 processor. It should be easily doable on any modern PC. Some of the hardware solutions available do this internally. You might look at www.cmlmicro.com. They have a number of signalling chips. They have CTCSS and others that do DTMF. Perhaps you'd realy want to have the thing entirely in software. I wouldn't tackle it in windows, but it ought to be straight forward in Linux. 73 Ed K3SWJ --- In Repeater-Builder@yahoogroups.com, Don Pomplun [EMAIL PROTECTED] wrote: What's that company that makes the little CTCSS encode/decode boards for $50.

Re: [Repeater-Builder] Re: GE Mastr PRO deskmate power supply question.
Reminds me of the Tremors - Wooden Roller Coaster at the Silverwood Amusement Park over in Idaho. When you get off the roller coaster, there's a sign that says The Gift Shop Sells Clean Underwear (and they really do, too, with the Tremors logo on it.) I've certainly had to wait to ride a few times while the crew did some cleanup due to someone wetting their pants. Maybe there should be some GE logo underwear for situations like this?!

Re: [Repeater-Builder] duplexer tuning question
Ok, I have some theroies, but I need confirmation from someone that is like good with math and formulas and stuff as you know I flunked my high school pre-algebra class. Anyway I want to make a 2 meter duplexer economy style as the person who is building the repeater cannot afford a trip to the Zoo let alone a set of big cans. So I wan't to build either a 6-pack or a 8 block of cavitiys, like the UHF mobile duplexers only longer. 2 - 3dB of insertion loss would be acceptable Doing some coaxial theory and using air as a di-elelctric. Will an inner conductor with a outter diameter of 3/8 and the outer conductor with an inner diameter 1 yield 70 ohms impedence? If not what would the impedence be? And what would the dimensions of the outter conductor need to be if the inner is 3/8? The present idea of mechanical construction is to use 3/8 copper solid ground rods cut to length for the inner conductor and encasing in either 1 or 1 1/4 pipe. Then there would have to be a bushing fabricated that has allen set screws to adjust the length of the center conductor. This design should be ideal for any frequency asuming the materials are big enough. I am planning for a Notch only style duplexer to keep costs down. Without design software I cannot acurately predict band pass or BpBr Q if the cavities have more than one connector. Also loop construction ideas are welcome as I currently am planning BNCs on the top with 12 ga straight down from the top and soldered to a hole in the side of the can. I am also considering a Teflon disc at the end of the tuning rod to act as a spacer for mechanical stability if the set is lied flat.
