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.
