[Repeater-Builder] Re: Master II UHF repeater station stays keyed...
This was a repeater config to start with. Worked fine with the onboard controller and when I had it on the hill with my RLC-5. In fact had it linked to my 2 meter machine using 1 controller for a while. I pulled the rx tone board(maybe that was the system board?) when I got it. Left the TX tone hooked up(the one on the right of the exciter strip). What I was saying was when I pull the connector going to the tone encoder(on the tx strip) the tx went off but would not key with that off. Was trying what Fred suggested. So it was a working full blown repeater that one day keyed on and when I went to the hill to check it there was no way to get it to unkey. No timer or anything. I can pull all but the 10v card and it will stay up. I can change the 10v card ( or the other 2) for known good cards and it stays up. I'm betting that someone out of this group will hit it soon!

[Repeater-Builder] Re: Master II UHF repeater station stays keyed...
Have you swapped the 10 volt regulator board with a known good one? It has happened that something can short a line on the back plain...this could be a key line to the 10 volt board. My point to having you check the locations were to find out if something off the board was pulling one of the key inputs low or if the board has a shorted keying transistor. If one of the lines are low, then follow it completely to where ever it goes, and check it for a short to ground. Something is pulled to ground to get the RED LED to turn on, or Q5 or Q6...more likely, Q6 may be shorted. If none of the inputs are pulled low then the problem is on the regulator board. Otherwise it is an input to the board. Now, there's nothing difficult about this, it's simple DC troubleshooting. You should be able to track it down in a little while when all other possabilities have been exausted then what ever is left must be the truth. Fred shouldn't have to come to help with this you should be able to track it down...You'll remember it better next time, and you will learn some trouble shooting tricks from it. We've all been here and survived it... so have fun. At least in your case it's not some police, or fire chief breatheing down your neck wanting his radio fixed now. 73 AC0Y --- In Repeater-Builder@yahoogroups.com, w4wsm [EMAIL PROTECTED] wrote: If the 10volt board is fine can it still be any of these?

Re: [Repeater-Builder] Re: Master II UHF repeater station stays keyed...
I had similar problems with one of my machines. The repeater would ghost key about 20 seconds after PTT droped. This was traced to bad PNP transistors on the keying circuit.

Are you doing these tests while using an outboard controller? Does it do it with the PA output connected directly to a dummy load? I'm wondering if you have excessive RF floating around that's somehow getting into the logic circuitry. Does it do it with PA disconnected from the exciter? I'm wondering if the power supply voltage is crashing under load, causing strange behavior in logic circuits. Does it do it if you key the station using the mic?

[Repeater-Builder] Re: Master II UHF repeater station stays keyed...
Just went down and checked a few things. Yes, CG is on transmitter. I pulled the cable to it and the TX went off. It wouldn't key with the tone disconnected...is there a jumper you have to use for no tone? It's the intercom button on the 10volt card that causes the tx to go off when you push it. I've noticed when the TX is off using this switch I hear a hum like it's pulling more power. Maybe normal but doesn't make the sound when tX is full power. PPT light is on on the 10v board. Never goes off even after pulling CG. This one hasn't had any mods. All original GE as far as I know. Going up on the hill to play with the other one now...

Maybe normal but doesn't make the sound when tX is full power. Probably normal. PPT light is on on the 10v board. Never goes off even after pulling CG. That doesn't sound right. Also confirm you're pulling the CG board in the system board area, and not the transmitter CG board. Stock GE repeaters have to use two separate boards, but if they were configured as remote bases, there is a board that will do both encode and decode that goes into the system board area (receiver CG board P908 and P909 I believe, but I'm at work and not looking at one) but it will not do them *at the same time*. This is why you have to use two stock GE boards or add a TS-32/64 to the GE stations to do a repeater that receives and transmits CG. In most configurations that are set up as remote bases... if you pull the CG board from the system board, the station unkeys. This one hasn't had any mods. All original GE as far as I know. Was it always a repeater, or was it jumpered as a remote base or ...? It kinda sounds like someone golden-screwdrivered it, but... I forgot what other cards you said it has installed. Any other cards in the cage? Also... if it has the stock repeater card, have you reduced the TX hang time on that card to the lowest setting? It will transmit for a while after the receiver closes, by whatever that pot is set to. Just throwing out some more ideas... If you're planning to run a ham controller anyway (since that internal one won't ID your repeater properly anyway)... you *might* consider pulling all the cards from the shelf except the 10V regulator, jumpering the station as a duplexed repeater from the LBI's and the docs on RB, and then seeing if you can get it to work happily with an off-board controller. But I understand the desire to get it working stock before changing anything. Both methods have merit, and I like getting the stock station working if possible before proceeding... Nate WY0X
