One of my repeater uses 2 power supplies - one high current (50amps) that powers the repeater xmtr, receiver, preamp and controller (guess which one I use? g). A 2nd, lower current one (35 amp Astron) powers the link and remote base radios. No problems at all this way.. just make sure you tie the grounds together and you're all set!

Re: [Repeater-Builder] More power, Scotty!
I've done things like this before. (dual power supplies) As long as I tied the negative leads together I never had a problem. -- Original Message -- Received: Mon, 24 Jan 2005 05:09:02 PM CST From: dekk5fm [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] More power, Scotty!

Sounds like a ground issue. Your Astron 35 amp power supply is actually 26 amps normal, 35 amps surge. How much power are you running? Some of the other techs can correct me if I am wrong, but to tie them together you have to use some diodes to prevent one from feeding back into the other. Then positive to positive and negative to negative. It's been several years since I have tied two together, but it seems that is the way we done it.

RE: [Repeater-Builder] More power, Scotty!
You can keep your loads seperated and just tie the ground side (negative terminals) of both power supplies together. This should take care of the problem. Connecting the power supplies in parallel to increase the current capacity can be troublesome at best. Good luck and 73, Kevin, K9HX At 06:15 PM 1/24/2005, you wrote: Sounds like a ground issue.
