I'd change out the LMR cable for something that will not cause you possible problems later on. You've spent good money for a fine system so far, don't jeopardize its operation by "going cheap" and using LMR for the feedline. The overall best suggestion is to use at least 1/2" hardline for this application, especially since you have a short run. (Longer runs woujld be better with 7/8 or larger...) Do *NOT* use LMR anywhere, even for your jumpers...
If you're not familiar with the issues surrounding LMR cable, search the message database at this group - you'll find discussions "ad nauseum" regarding the use of LMR and its being prone to noise when used in duplex (repeater) operation. Of course, YMMV... 73 de Mark - N9WYS -----Original Message----- From: [email protected] On Behalf Of atms169 Yes, I have spent a lot. It's a Dstar repeater.
