When I connect the big Red and Black power leads to the PA to 13.8 volts, no power reaches the rest of the station. The schematic in the manual shows a cable from the power supply going to the backplane or motherboard, but I do not have it. There is a 15 pin connector at the top left of the rear Chassis (not motherboard) with nothing connected to it, but I don't see any number reference, so I don't know what would connect to it. Can someone give me help here?? Thanks. 73, John, K9KA

I've swapped ALL the cards with known good ones. OK, are you talking about the cage itself keying it? What other board is there when all the cards but the 10v is pulled? I know it's hard to do this without being here...hope to get Fred out here soon to see what magic he can work:-) Ben --- In Repeater-Builder@yahoogroups.com, Coy Hilton ac0y8@ wrote: If you have a schematic of the 10V regulator board and or the back plain if the card cage check in this order. 1. On the back plain Pin B12 of the 10V regulator board connector. 2. On the back plain Pin D4 of the 10V regulator board connector. 3. On the back plain Pin A14 of the 10V regulator board connector. 4. On the back plain Pin D3 of the 10V regulator board connector. 5. On the back plain Pin A12 of the 10V regulator board connector. IF any of these are Low0 or less than a volt or so then the key request is comming from off the board to the Keying circuit on the regulator board. If none of these are pulled low then it could be either Q5 or Q6 on the regulator board most likely Q6 will be shorted it actually Keys the Tx and turns on the LED. THe schematic for this board is on the Repeater-builders website where the LBIs are posted. Good luck! AC0Y --- In Repeater-Builder@yahoogroups.com, w4wsm b.runner@ wrote: Repeater. Does it with only the 10 volt card when no controller is hooked up. This started it's life as a repeater. It's not a remote base. --- In Repeater-Builder@yahoogroups.com, Fred Flowers fred_flowers@ wrote: Yes there is a jumper. Is this a repeater? Most likely the trouble is the receiver or controller.
