rick is right. It sounds like a bad 10.240 xtal. I experienced this recently with a connex 3300 and a galaxy 44

after close examination and troubleshooting, I replaced the crystals on pcb and bam! sucker is up and running again

btw this is a 14b pcb

ive decided to put this on the back burner 4 a bit but this saga will continue. thx rick

its getting worse the more i use. allmost will not transmit at all. static was in rx also but it doesnt seem to be anymore. which ic or transistor actuates the tx? thx peeps

A multi-band, end fed, terminated "L" antenna? thx peeps

any input would help. thx

this thing needs to be rewired internaly. does anybody have one? if so, could i get a peek insde the mic? any pics would be greatly appreciated

Thanks for the input scott. this is a 1989 model. well rick, i will get the voltage readings from audio chip first thing tomorrow. I could just as well toss this pos but its personal now. cant let it win! thx peeps

well Rick, I replaced audio transformer and audio chip and nearby caps... still no recieve. any more options? again thx

sorry about my vague descriptions. it was not intentional. "I cant hear pa thru ext. spkr" means: when I plug in an ext. speaker into pa jack and switch radio to pa, I dont hear my voice coming out of the ext. spkr. keep in mind, the radios tx and modulation work great. ref. your second re...

ok, the base voltage of tr6 is zero when closed and 1.16volts when open. tr10 base voltage varies from 0-8.8volts. d4 thru d7 all ok. I noticed that i cant hear the pa thru an external speaker. also, I can hear incoming audio barely with earphone. your time is greatly appreciated rick. russ

this 25 tx is fine with good modulation, do you still think it could be the audio chip? thx

this radio seems to have had moisture contaminants. all pots check ok

well, my 2950 used to do the same thing. the first time it happened, i found that the ext. spkr switch that turns off the internal spkr was'nt making contact because of residue buildup. second time, was a simple case of the pcb screws being rattled loose. hope this helps

the saturn base uses the same pcb's as like models 88, 99 mobiles. cbtricks.com , gl

Thank you. The problem was the jumper board. Apparently, someone had Knocked it loose.

I was wondering what might be the problem with this one. At full throttle it will dead key 1/2 watt and swing allmost a watt. I just aquirred this radio so I dont have any history info to add. I have checked the driver and finals plus the predriver and all are ok. can the big transistor regulator ca...

Can anyone identify this amp? It seems to have the characteristics of D&A.

hey rubbandman, I sure would appreciate a manual for my maverick 250, If its not too much trouble

Hello, I have mediocre experience tuning tube linears but recently accuired this D&A. I was suprised to find so many different things to tune. my question is, what is the proper sequence to tune this amp, should I be finding the max output for each, how does the grid tuner on back of unit play i...
