Kenwood TK820 Repeater

Post by chartofmaryland »

I would like to interface a Motorola Comparator to a Kenwood TK820, is it possible and what would I need to create this beast?

Is this comparator going to be used in the TKR-820 as a voting setup to make the TKRa remote/sat reciever etc? The kenwood should be able to interface with it. I have (well not me, the technicians who put together what I sold and thought up) interfaced a whole lotta obscure crap to those things in my day, and they are very open to modification. Thats one of the things I like about kenwood, they don't get up in arms when you take some thing they make, and try to make it better. /\/\ would probably be asking all types of questions and say you violated some type of intellectual property right.

Well, I looked all of the way into this with the help of the wonderful people of this board and still came to the concluion that nothin beats a micor when you want to use spectra-tac.

In the end I found that for about the same amount of money and time, the answer all along was to finally replace the 273 ft. run of times somethin hardline with *Andrew Heliax* 2 1/4 Air flow while pumping hydrogen through it. MAN!! am I on a system now!!! The total range went from 10 air miles to over 70!!!
The thing to remember is when you have loss eliminate it. And then you can hear the repeater, and the repeater can finally hear you!

So if you can't afford a spectra-tac system, max out the system you have first and then go from there, unless you have to sprit radios soldered together and relays controling the functions feed through rg-259 and a magmount, then buy the micor and start building.

Thanks again for the help!

Isenit it amazing what a repeater can do with a good connecton to the antenna!!

Wow, what a big "hose" you have going up to the antnna, but that is what it takes to get the RFs up there and the weak signals back down to the receiver.

I would also agree that the micor, although older, plays on a completely different level than a TKR-820. The Kenwood is a desktop repeater for christ sake, I mean you can't really compare the two. That would be like comparing a gr1225 to a quantar. Good luck w/ your gear.

I hope you meant to say NITROGEN. In other places they use an air compressor that dehumidifies the air before being placed into the coax. A pressure of about 3 PSI will work just fine. If all is done correctly and the connectors are installed by a knowledged person, your cable should hold pressure very nicely.

The hydrogen makes the coax lighter and easier to install. Hell it worked for the Hindenburg. Sucks for the tower climber that cuts into it with a cigarette in his mouth though.... :lol:

Well I have the story straight, the hydrogen was run through the line for just a little while so to prep the line for the dehydrator. Don't ask me why because it was translated *german* the way he was explaining on how it worked. Radio tech, no, but a one of a kind gas tech from a local gas company. In the end the dehydrator is hooked up and its working now a little better than before.
