I will avoid going into the technical and political rant of... "Why cheap mobile cross-band repeaters hooked to my properly working much more expensive real repeater are bad...", since we've hashed it out here on this list before, and just say this:
Call the repeater owner of the repeater you're THINKING about doing this to, and ask their opinion of it. If they say, "Please don't do it." Respect their wishes. I can definitely say that in all the time I've run repeaters, the only two things I've had to DF were jammers, and mobile cross-band repeaters built into user rigs that were set up wrong -- where the owner wasn't able to hear that they were stuck in transmit -- that I as a repeater operator had no control over -- that were parked somewhere transmitting crap into our repeaters. We generally do not welcome such operations on our systems nowadays. I can tell some people are doing it, but they seem to have their heads on straight, always run CTCSS on their "input" frequency, and pay attention to what the thing's doing. Had one ham years ago that would put his carrier squelch only crossbander in that mode and parked his car in a parking garage downtown (high RF environment) for two weeks straight with it transmitting crap into a high mountain repeater. A little hunting found his input frequency and it wasn't me, but I know who ran his truck battery dead... on purpose. I would have been happier if it'd blown the finals, really... after two weeks of listening to the thing and three days of actively hunting it. Think about the following: - Are you going to give a way to control your cross-bander to the control operator of the repeater you're connecting it to? - Is your crossbander going to ID and let folks know it's a cross-bander so they can come beat you with a Wouff Hong if you lock up their system? - Does your FT-8800 properly ID, or are you ID'ing it saying you're operating through a repeater? I'm actually TRYING to be nice here. The words "cross-band repeater" make my blood boil, since I've been on the receiving end of... "Bend over, I'm hooking my crappy cross-bander to your repeater with 150 miles+ of coverage but my crappy HT and rubber duck can't hit it, and I am too lazy to do the RF math to see that I just need a better antenna at VHF"... end of this far too many times... There are just better options... lots better... Think about who you'll be inconveniencing if you build a cross-band repeater, and build in a way for THEM to turn it off... over the air preferrably, but a phone line power switch would work too. That'd only be reasonable since they probably already have that feature on THEIR repeater you're linking into... if they built theirs right. Sorry about the rant... if you want REAL ideas on how to do something totally different so you can communicate with the far-away repeater... holler. Plenty of ways to do that without a cross-band junkpile... at least you were looking at relatively good rigs for doing it... compared to that broad-as-a-barn-door front end on that FT-8800! -- Nate Duehr, WY0X n...@natetech.com On Tue, 30 Jun 2009 15:42 +0000, "turboelesjuan" <kd0...@gmail.com> wrote: A little background on what I'm trying to accomplish here; I'm a member of a Ham radio club but do not live in the city the club's repeater resides in. Due to the distance away I'm unable to access the repeater with a handheld radio without the use of a large external antenna and thats what I'd like to change. Installed in my vehicle is a Yaesu FT-8800 mobile that has ability to perform crossband repeat option. Example: A: 145.170MHz (-600khz offset) B: 438.500MHz simplex. I have a UHF Radio that I can set to 438.500MHz simplex to walk around my house and both TALK and RECEIVE traffic to and from the repeater. Basically the radio in my car has the ability to transmit and receive on BOTH frequencies. Heres my question: Is there a controller I can build which has the ability to control TWO Motorola GM300 mobiles w/16pin connectors the same way? Use each radio as a transceiver for bi-directional traffic? I already have both of the GM300 radios and they didn't cost 400$, which my 8800 Did. I want something perm. installed at my house so I can use a small UHF handheld on low power anywhere around my area to chat. Is this possible?
