this board is going to be very similar to the early galaxy radios like the DX33HML. there will be differences in the PLL section, and the offset crystal used will most likely be a different frequency, but the rest of the radio should be pretty much identical so you can use their alignment...

you should replace both of them, not just one of them. here is a pair for a pretty good price: https://www.ebay.com/itm/306397250650?mkcid=1&mkrid=711-53200-19255-0&siteid=0&campid=5336136228&customid=&toolid=10001&mkevt=1 be careful with the installation of the new parts as they may be...

is this the one with the dual audio amps? If so, i believe there is a thread i started years ago when i was messing with the one i have. I need to get back to that radio someday... LC

looks like they did a good job on the 4 pin conversion but that bit white cable tie is most likely not factory. i could be wrong but i don't think ive ever seen one that size used in an old uniden/president radio. LC

the other way to tell which washington you have is the number of buttons on the lower right. if you have three buttons, its the 8719 version. if you have two, 858. UPD858 version: MB8719 version: LC

Brandon, if you have a four pin washington, then it is the upd858 chassis, which already has a compressor type circuit built in. I only mention this because you might want to bypass it when testing your external unit with this radio. If i remember correctly the way this used to be done in the...

just spitballing here, but you might try putting an ohmmeter from chassis ground to PC board ground, with and without your coax to the dummy load connected. in both cases, you should have no DC connection between them. LC

LOL i bet that 15 seconds took someone a long long time to create!

you're in Luck! i do happen to have one that doesn't work and ive had it so long i don't remember what did or didn't work. I believe one of the meter windows is cracked. it is complete i believe but is not screwed together. you are welcome to it, and just need to cover the shipping. Unless you...

i think your problem lies in the circuit containing Q30, Q31, and Q33. i know you said you already checked them but any experienced tech will tell you that it's always the thing you're already sure its not. It takes some doing to get the right info for a situation like this because its a...

There are some mods that can be done to that chassis but i can't remember what they are. I'll have to look at my SAMS manual for that radio as i think i made notes on what can be changed. somewhere out there in CB land is an 89GTL that i put an RFX-75 in. I called it a street sleeper as it...

if this radio has the same board as the original RCI-2950 then its right next to L6. LC

do you have a way of checking how deaf the radio is? Like, a signal generator with a calibrated output. put a 1K tone into the radio at 30% modulation and see how far down it can hear. you should be able to hear at least down to around -115dbm and im used to galaxy receivers still picking up...

10 volts does seem a bit low. here are the correct voltages for the audio chip: LC
