What is RG75? what are its characteristics? The only RG-75 I know of was a type of rectangular waveguide for microwave. There must be another factor causing your problem. Please don't take this personally as I've experienced all the problems I'm about to list. Poor soldering, inner conductor shorting to the shield at one of the connectors, flux on the end of the center pin of one or both of the connectors, lousy connectors. The quality of some RCA connectors and plugs has become a problem. The ring which is supposed to connect to the body of the connector makes poor or intermittent contact. The solution is to solder the ring to the connector body before soldering the cable. Flux on the end of the center pin can be the cause of no contact with the receptacle. I now clean my solder joints with alcohol. As far as correcting the center conductor shorting to the shield problem: work fast. If the cable passes continuity with a DVM or equivalent then the problem is internal and not! due to the cabling. As stated many times before, almost any type of coax will work.
-------------- Original message -------------- From: "Dan Ringer" <[EMAIL PROTECTED]> What are others using as an INJ cable for the R4x-T4x combos? I know that Drake provided such a beast "'back in the day," that Belden 8421 works well, and that there are a least a couple of RG type cables that do, also. But where do you get it??? I don't really need 250 feet to make one 38" cable, and I doubt I'll find an acceptable pre-made cable locally. Is there a commercial (or sort-of-commercial) source? I've searched the archive's, the various Drake web pages and the 'net generally, without any clear success. I certainly don't mind making the "cable," if I can get the "wire." I know Garey, K4OAK, has stated that pretty much anything will work, if the units are aligned with the cable in place, but is that literally true? I've tried RG75, but can't get the receiver to align properly for transceive. Although the received signals sound fine, I can't get both units on frequency. I'm inclined to think that I can't just plug in any old cable, of any old length, and expect it to work. Suggestions wanted! Thanks! Dan, K8WV
