[Repeater-Builder] New repeater buildup
Hello group, I have the opportunity to put up a UHF ham repeater in a fantastic spot. However, I have some pretty stiff requirements. It will be co-located with an existing Govt. repeater, which is solar powered. I do not have to supply the battery or PV panel, I will use whats there. I have already hiked up and installed the DB408 + LDF4-50 / Polyphaser. Lets see what the group can come up with... 1. Needs to be as light as possible, since I have to hike it up to the top of an 8K feet peak. (5 hour round trip). 2. Must be efficient, no heaters on crystals, etc. 3. Must be able to operate over wide temperature ranges, no heating or cooling in the box. 4. Will be solar powered. 5. I am thinking a maximum of 10 watts. 6. It needs to be robust, with resistance to lightning strikes. 7. I picked out a controller, the NHRC 4, seems pretty nice. I want it to be able to turn ON / OFF the main TX in case there is trouble. 8. I need TX board, RX board, and an RX control RX (420 region). 9. I already have the duplexer, a mobile type Celwave product. I was thinking along these lines: Obtain the RX and TX boards from a MOT MSR2000 repeater, repackage them in lightweight BUD boxes. Install the controller in another box. I know the group has better ideas, and I would love to hear them! Let them flow! Thank you in advance, Tracy Yahoo!

Re: [Repeater-Builder] New repeater buildup
get the Maggiorie transmitter and receiver boards. they are 3x5 in size. draw very little power and you will be running 5 watts right out of package without an external amp... I dont think you can get any smaller than that... Neal hooker wrote: Hello group, I have the opportunity to put up a UHF ham repeater in a fantastic spot.
