hey ramblin man your the smartest cb man i,ve everrrrr seen online ...i also have a galaxy dx-66 acting crazy it will be working fine then all of a sudden it hums and sounds like somebody on another channel is talking and the freq.counter goes up and down if i turn it off and back on several times it will go back to normal for awhile then go nuts again seems like if you leave it on awhile it quits i,ve tryed a toothbrush touching on the circuit board trying to find maybe a bad solder joint but have no luck what do you think is causing it

hey there tim,id check two things,first id check c-199,id also resolder the two legs of the 10.240 mhz. crystal.c-199 has been known to cause what your describing a buzzing sound on rx and tx.also if the 10.240 mhz. crystal gets a loose connection on one of its legs,it can cause frequency shifts.and by the way,no cb god here.there is only one god,and as the bible says he who knows this does well.i am just learning alot like a lot of others.thats why i come to these forums to learn.and as far as the man goes,my opions is there is one cb man on here,and its rick,cause he really knows his s**t.he has helped me out alot,and i try too help out others here when i can...........your friend jimmy a.k.a.....ramblinman

well from what i,ve read whatever you tell people to check it usually fixes their problems i really appreciate your help

thank you rick for helping ramblin man help me

sorry to worry you ramblin man but could you tell me what area c-199 and the crystal is located at in the 66 i cant seem to find them

hey bub,well lets see here.now with your radio facing you,knobs toward you.look on the front right corner back approx.,2 inches,you should see a small eight legged i.c.,this is labeled ic-4,this is the mic amp/tr switch,right behind it you should see two small can capacitors,these are c-131 and c-132,then right behind them a bigger can capacitor,bingo its it,c-199 this is a 330 uf at 16 volt capacitor.change it out.then look on the left side of the radio about two thirds the back and to the left,you should see a group of tuning cans,about 13 to be exact.the first one you come to,this will be l-17,it is the v.c.o alignment,look just to the right of l-17 and bingo there it is .it will be labeled x-1 on the p.c.b..but you probably wont be able to see it.cause it is usually covered in bees wax around this area of the pc board.but if you look on the inside of the cystal,it should be labeled 10.240 mhz..........good luck bub,,,jimmy........ramblinman

ok,thanks can you get a replacement c-199 cap from radio shack if not i know another place that would have one just they,re not open on weekends

oh i forgot to tell you i was putting a new audiochip in my 44 and i dropped the little plastic screw on the floor somewhere and cant find it for anything can you rob one out of a old junk cb or does it have to be from a galaxy

thank god i found the little plastic screw

yep,you should be able to get them at the shack,only problem is youll probably have to but a whole darn pack of assorted capacitors,just to get the one youll need.what a country huh.....you might just rob one out of an old radio,if you got one laying around.330 uf at 16 volts,or 25 volt,50,it really dont matter as long as its at least a 16volt or greater,and its not to large to fit into the area youre working.just make sure its a 330 uf.and as far as the screw goes a screwbeascrew........ramblinman......

ok,thanks i have boxes and boxes of old mobiles in my shop from 23 ch...and up plus a big stack of bases i have one old base linear runs off ac has like 1 or 2 tubes in it works like new got it at a yard sale for 5 bucks

hey tim,i see where you said,you have alot of old radios 23-40 channels,and some old bases,and base linears........you get ready to sell some of it or all of it.let me know i might be interested in buying them.....working or non working.........................ramblinman
