Re: tk-760-h panel lites gone

O.K., here's the latest.I have 1.02 vdc on that line, all the way to the ribbon connector. I traced that across the main board to r-247, which has 13.8 vdc on the supply side. R-247 measures 440 ohms (within specs). I get 13.8 on the output when the control board is unplugged, it drops to 1.02 when ...

Re: 4150 Programming help

Don't know but the factory cable that P.S.I. in Fife had ran off of comm 2, on a really old, slow computer. He said they wouldn't work on anything newer.

Re: SM-2150 Blinking Lite?

O.K. found out the blinking lite means it is in scan mode, didn't know they had scan. Is there a way to turn this off on the front panel?

Re: tk-760-h panel lites gone

Still lost on this one. I can't find q405. The highest vdc+ i can find on the mike connector is 4.95 vdc+. From what i can gather the desk mike requires 8vdc+, it isn't working. I also can't find a pinout for the 6 pin mike connector. I can find a good ground for what i suspect are the mike and ptt ...

Re: 4150 Programming help

The red wire goes on the left most pin (5v) of the relay board header, after you pull the relay board out. You can reprogram it again if you haven't blown something on the circuit board. Another trick i learned recently is turning down the supply voltage to 11.0 to 11.5 volts to aid in programming (...

SM-2150 Blinking Lite?

Converted a SM-2150 over to repeater service and ran into a problem. I'm using the call lite 'link' to fire the base of a NPN transistor controlling a reed relay which activates another SM-2150 in transmit mode. Receiver is programed for 3 freqs in the 151 Mhz range (working freqs) and 1 freq at 158...

Re: tk-760-h panel lites gone

No markings on the board except some ic's so a partial schematic would be much appreciated. Also is the"sb" line the one voltage line on the mike connector or is there more? Is it 5v or 12. Thank you for your help.

tk-760-h panel lites gone

I have a tk-760-h (fcc id says h-1) that the panel lites went out on. The desk mike seems to have quit working also. I read thru the previous posts and wasn't sure what applied. This panel has 3 leds at each end, and sounds more like an early -g than a -h, from what i have read, it is not equipped f...
