I work with a guy that retired from the Air Force as a combat controler. He was telling me of how thay could take two handhelds and a cable with a small box between the two radios and put it on top of a hill and could get it to relay from one valley over the hill to the next valley. Is this posible or is this guy up in the night?

yes, very possible...ask ricciticcitembo, he's got some CRAZY stuff going on...a handheld repeater set up and some insane duty cycle going on
click search .... and look for "saber and repeater"

There is some info here that explains the operation.

And yes I build these modules for Maxtrac and radius mobiles, but haven't done one for hand helds. The big problem is the cable connectors to the portable radios, everyone is different.

Im so confused.
I need to come up with something that I can stick on top of a hill somewere so that I can talk with my teams on the other side during a search. The command center always seams to be at the bottom and on the other side. I dont need a lot of power just enuf to cover 5 to 6 square miles and relay the signal, is this route that I want to go? Its low power consumtion is a plus, and the small size is ideal, plus I have the handhelds to work with.
Would thay be conected thur the external speaker mike connection?

Radio Shack 'repeater maker'. Get 'em on eBay.

If you have some serious cash burning a hole in your pocket, I've heard some very positive things from folks who have demo'd these:

A bunch of departments are looking at them to, among other things, allow remote Nextel connection to their radio systems.

i clicked search...and in the box typed in
saber and repeater and clicked search and the 4th one down was by ricciticcitembo, and that was it...however, his best thread is
http://batboard.batlabs.com/viewtopic.php?t=34329 about his saber repeater. most of the stuff can be simplified by getting the pinouts for what ever equipment you are using, and just going by a template and hooking them up to cross-band. it's not that hard, minimal skills are required, and it can even be portable to portable if you're so inclined...or you can do what i did, and built it into a army ammo cannister and made it weather-proof and durable...if we go somewhere that we need a simplex repeater, you flip a switch on the inside, seal the top, drop it on the ground, and walk away.
Will has some good modules on his echocomm site, the extenders are pretty much what you're looking for, if i'm reading your post right. A RICK is probably a little pricey for what you want, and might not be the most portable thing in the world, (as compared to 2 piggybacked portables) Nand posted some PDFs from his ultimate uber wiring bible and 900 years of experience that work VERY well....i'd actually like to tell you that Nand's setup went online for a heavy duty repeater outage for us, and performed VERY well, at a total cost to us of like 13 dollars.
If you're doing SAR and you need something for bad geographical areas, with p!ss poor propegation, i'd suggest a pair of maxtracs, a gel-cell, and your variety of linking them (either RICK, extender mod, or a direct wire) and some decent antennas. With some creative installing, this will fit in a military ammo box and can be set up rather nicely for drop-n-go work, and the maxtracs will give you enough nut to get around in some crap, far more than a p!ssant little portable on a 1800mAh battery.
hope this helps

JPS makes a nice interconnect unit as well. I think it is called the ACU1000. Vega makes one that directly interfaces with their VoIP console. Lots of neat stuff out there.

The Forest Service here in the west has been using two Bendix King portables in a box with a simple cable interconnect for years. They fly or hike these in during fires and set them up with a battery that is speced to last 10 days, but they change them out every 5. I don't know what they use for a duplexer but this is just one way. Icom made something similar years ago, I suspect even Moto has one if you dig deep enough into their "skunkworks".
The Forest service also uses the Tait portable repeaters as well, but heavier.

Sounds like the "EFJ / Transcrypt
Tactical Interoperability Kit" or TICK

There are TONs of manufactureres, one of which is LINK Communications, that make tiny black boxes that are designed to make a repeater out of any two radios, including two hand helds.
http://www.link-comm.com/security.html
Radio Shack makes ( I own one) a tiny handheld device that has an internal digital buffer that stores up to 2 minutes of audio, and then re-transmits it. This way, their single radio acts as a digital store and forward voice repeater. It costs I think $49, it has excellent audio quality (I can't tell the difference from the input FM and the output FM voice/signal quality). I think they make one for 144-148 MHz, and one for 440-450 MHz. Mine is about two years old, and I'm not certain if it is still a current catalog item.

It got cancelled at least a year ago Larry, was actually a decent product for the price. A rare find at that store.
