The ID-O-Matic can also function as a very basic repeater controller at only 
$20...  check out http://www.hamgadgets.com/product_info.php?products_id=64

I'd recommend what W5ZIT mentioned, or the model I was thinking of was
http://www.nhrc.net/nhrc-2/

Now that I see it's under $60, I may have to get one myself! Not sure
what I'm going to use it for as there are too many repeaters in my area,
but I will use a controller for a cross band repeater...

Re: [Repeater-Builder] 900mhz , DTR, 906 to 923.75 MHz FHSS

2008-11-17 Thread ANDRE 
thank all,

Yes, i am im Brazil, and we use GMRS radios but we do not need GMRS licence 
here.

I can use 900mhz dtr or UHF GRMS radios, i have both.

But here, the 900mhz is more clean than the uhf,

So i thoght to make a digital repeater for this DTR or other fhss radio, but i 
do not know any a apm, and the repeater that are FHSS (or do not need to be?)

John, will you recommend any repeater (small) GRMS?

Thanks ALL

( i do not want to buy a UHF comercial Licence  to install a big repeater only 
to me)

  An idea is to use a simple repeater controller connected to the radios'
  speaker-mic connections.

  one radio will receive only, one radio will transmit only. Make sure you
  keep them separated about nine feet or greater if you are going to use
  the amp on the one that is going to transmit.
