Hi Steve I haven't had a chance to remove the pre-amp. Here's the story...
My handy-dandy motorola tech came to the site about 3 months ago to "help". He told me I had about 6db-10db of desense according to his zillion dollar service monitor. He was wanting to sell me a used Celwave 5042-1 duplexer he had. He offered it to me for a good price...$600.00 so I bit and we hooked it up and tuned it. I asked him about the preamp and he said I should leave it in place. I said OK and he went on his merry way. A ham buddy of mine and me then took off in different directions to check out the "new" system. The desense was worse than ever!!!! Just a few miles from the site, any attempt to use the repeater caused the repeater transmitter to key on and off constantly. Next day, I went back to the site, removed the celwave and put the sinclair back on...problem went away. I got home and looked up the specs on the celwave and lo and behold, the sinclair had much better specs. The radio tech blamed everything on the antenna I have, which I know causes some problems, but like I said in an earlier post, my options are somewhat limited (any suggestions in this area would be welcome!). Needless to say, I've not used this guy again. Anyway, I haven't removed the preamp. If I do remove it, does the receiver need to be retuned? That's one reason I've not removed it cause its a bit tough to get my equipment to the site if retuning is needed.
