RE: [Repeater-Builder] A couple of questions about hard line
Okay sorry about the spelling errors but the coax I have came from a guy who moved to Florida a year or so ago via another ham who's call is k4rjj the numbers on the heliax are as follows he believed that the guy used this hard line on a antenna system or repeater in Marietta, ga 84147 LDF5 50 ohm HELIAX COAXIL CABLE 52401 A04P I have three sections of this cable. one looks like it has a ground kit on it all sections appear to have connectors at both ends that have rubber protectors on it protect if from weather. Now I need to test this before I install it The tools I have on hand are Mfj 269 Diamond watt meter swr bridge 50 ohm dummy load and various radios Can I do a decent test with the above? If so how? I plan to use this on my repeater's antenna(443.400 + 107.2) which I am putting a tower up for this month. I am going to put an 80' tower up the repeater antenna is going to go to the top of a 10' mast section sticking out of the top of the tower. Eventually I want to put a beam on the mast and a rotor. I figure I am going to have to use a jumper from the hard line to the antenna to get around the rotor I figure this will be about 10' long. What type of coax to use for this jumper? Is there a better way? How do you attach the hard line to the tower? Will wire ties work for this? Should I remove the existing ends on the hard line and put new ones on? Guys what I am forgetting about this install (which at my house)? Or what should I be looking for? Yahoo!

Each digit was made up of two tones, but not similar to the Touch Tone frequencies. Your taking me back to my old phone company Toll Office days and the 17B board. 73, Joe, k1ike Of course none of this is really used much anymore, anywhere. Nowadays, we're using fiber between Offices, and if you can find MF doing anything, you've found a system in sore need of an upgrade or a tandem connection to an even older device somewhere the stuff's still used, usual International circuits. In-band signaling hasn't been desired or good engineering practice for many years now. While system size and complexity continue their downward slide, capacity in telco keeps going up up up. The teleconferencing box I work on uses 6 co-ax cabled DS-3's to feed it (or optionally Fiber and IP/SIP/VoIP). It's a beast. (Reading through the logs is REALLY fun... um... no. Nevermind...) It handles 4032 phone calls at the same time in just about any combination of conferences you like... in a one and a half-foot high box. The bummer for most carriers is that conferences last a long time, completely blowing their traffic management folks out of the water. One of our boxes can utterly crush the inter-machine trunks between the IXC's and other carriers out of a CO in smaller offices, with too much traffic that lasts longer than expected for an average phone call. I hear rumor that one of our customers did this to Sprint in the Atlanta area recently... new system turn-up, Sprint wasn't watching traffic load carefully enough... all circuits busy out of Atlanta... Ah well, what'cha expect from a railroad telephone company? (SPRINT = Southern Pacific Railroad Internal Network Telephone... or similar.)

What to look for to determine this? What kind is it? It should be listed on the jacket. In general, N and PL259 connectors for most kinds of coax can be found for not a whole lot of money on Ebay. I've also found good deals at swaps. If the coax is unterminated, look into it with a flashlight. If you can see water marks on it, you probably have something which at least needs the ends chopped off to get around the water damage, to having a somewhat worthless chunk of copper. Even hard line with no obvious damage can be bad; I found that out the hard way once. Really, the best way to test it is to stuff some connectors on it and see what the loss is with a watt meter. --STeve Andre' wb8wsf en82 Yahoo!

The easiest way is to put connectors on it, a load on one side and swr bridge and radio on the other and see if it loads up. You need to know what brand the heliax is.

Re: [Repeater-Builder] A couple of questions about hard line
Hi, I believe the term Multi-Frequency was used to describe the early ATT inter office toll dialing scheme. The tones used were not the tones you hear on your telephone - but another completely different group. If I dig around here far enough, I may still have the information. Mike, WA6ILQ, may be able to detail this better than I or, perhaps, a retired ATT or Western Electric systems engineer.

Re: [Repeater-Builder] A couple of questions about hard line
The MF or Muti Freq. tones were even numbers 700 + 900, 700 + 1100, 900 + 1100 for 1, 2, 3 then they used 1300 1500 1700 with the other low group for the rest. This was known as In band signalling and is what the operators used on their tandem trunks (Inter office circuits) to place long distance calls.
