Why when I first installed it into my car and I have a K2 antenna I think that is what type of antenna it is, not exactly sure. It's a 40 channel radio with WX 3 channels. I noticed after I installed it into my car, this was in a warm garage. It's a 7 footer too. Then after it got real cold I noticed that the 4 lights for the tx and rx power lights when I am transmitting it goes one light when I push it down it and then it flickers to 2 lights and then goes back to one light after it is pushed all the way down, also sometimes when I talk into it it sometimes will flicker to 2 lights again but only for split second. It was fine when I first installed it in the garage? Please help me I would greatly appreciate it!
