Thanks. Yea it seems very rare. The mic pin out is the same as a Midland. If that tells you anything. Only thing I was able to find on the web is that the Midland 79-265 may be the same board.
Ok just wanted to give an update. With the help of a tech I got the frequency tuning cans figured out. At least mostly figured out.
The only number on the board is ss-700. I'm going to try and attach a photo.
Hi,
I have courier galaxy iv and need any and all information for this radio please. Can't seem to find any alignment info or a service manual. It's off quite a bit on ssb transmit. Making it unusable unless someone happens to tune me in. I have bk 1801 frequency counter. Just need to know what...
LC,
That's helpful information. Thanks for taking the time to explain everything. I have the recap kit ordered. Hopefully it will be here for the weekend. I downloaded the schematic you were talking about and will use it like you said. Also I will give the caps you mentioned a look first...
Well I did like you said with checking the pins. Pin 1 had no voltage. Unsoldered the leg for pin 1 and rechecked it. Sure enough no its showing 8v. So you think I should get one of those recap kits or try chasing down the exact part that went bad? Thanks
Ok LC I'm going to check the voltage on the pins of the regulator the way you said. Won't get time till tonight or tomorrow. Will let you know how I make out. Thanks
I tested tp9 for voltage got 17 mv. I'm not really sure how to fully read the schematic. Do I follow the line that says always 8v over to the pll? If so what would be the first test point as an example? Also I put the frequency counter on all the pins of the pll and got nothing. Thanks for...
So I have 8v on the mb3756 chip and 13.8 on two other pins. Nothing on any of the pll pins. Also the area around the mb3756 was getting very warm. Any ideas? Bad caps, bad pll?
Ok thanks for the advice so far. So should I check for the 8v rail first? I won't be able to get any work done on it until tomorrow. I have pretty much all the basic testing equipment needed. Just didn't know where to start first.
