First, becuase I have them, they already tone in them, and you get two receivers in one, and since it is in a low rf enerfy location, why not. As well the receiver's will all be the same. By the time I find 4 receivers that match, get 4 xtals, then tone boards, the money would be the same, then

RE: [Repeater-Builder] I need to take 5 volts to 8 volts, and one have a schematic

The 5 volt CAS signal from the TM-V7 can very easily be converted to an 8 volt (or even higher) level by using a VP0300L switching MOSFET and pullup resistor of about 510 ohms to your 8 volt source. If logic level conversion is required, then use the VN0300L or 2N7000 MOSFET. They are available

What he really is talking about is level translation. I'm getting ready to interface the Kenwood TM-V7 radios to the RVS-8 voter, am told it needs at least 8 volts to run it. I'm not sure what it is he's trying to run here, but that implies power. Yahoo! Groups Links * To visit your
