i'll just add to the already great advice here to say that the temptation to increase the value of the filter caps should be avoided. yes, you can increase the value of the main filter cap where Vcc enters the radio. I do this on every radio i do. however, increasing the value of the filter...

i believe this is the one i used: https://cbtricks.org/radios/rci/rci_6900_f150/ LC

service manual says its VC1 which is located on the freq counter module itself. LC

an easy way to do what Brandon is telling you, and it is the correct way, is to put a current meter on the power wire going into the radio. put the radio in SSB mode with mic gain all the way down. install the "mirror board" that goes in front of the final and driver. now key the mic while...

Nomad, can you explain a bit about what you mean by "inside the wattmeter"? LC

if this is the washington with the MB8719 PLL chip in it then change R204 to a 1.2K ohm resistor, and add a 1uF non-polarized capacitor from pin 9 of the audio chip to the junction of R121, R204, and D62. make sure to restore any modulation mods to stock before doing this mod. you do need a...

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!
