Stryker 490hp

[Chevyboy89]

Hello all, new user here from the Bluegrass state with a odd problem. I was given a 490 Stryker still in the box by a family member who doesn't use any form of cb, how he got it I'll never know. While in use I noticed when I talked the meter will stop swinging and I'm no longer able to hear the Roger beep through the TalkBack speaker. I can cycle the power once or sometimes many and it might work for 3-4 minutes and will stop swinging mid conversation. What could the problem be? My standing wave is below 1.5 on 1 and 40. I appreciate any and all help.

second hand radios can have problems , take off the covers and blow it out, or maybe the mic itself has a problem, or broken wire,
what do your contacts say they hear? check the ant for a broke wire, and the co-ax too.
intermittent also makes me think of a heat problem on a part. at that point you should take it to a radio repairman,
after re-reading this, i have to say, take it to a repairman because most strykers i have seen get abused, tweeked to their limit, and fry something.

Those radios were prone to cold solder joints, most likely the case. there is a tip on how to find them, hook the radio up to a PS and dummy load or antenna, remove the cover on the solder side of the board, with the eraser of a pencil touch around the board at the solder, if the radio blinks on you found it. The other is like 443 says, take it to a tech, he probably knows exactly where to look.
