Normally when the power drops the driver transistor needs to be heated with the proper soldering iron (poor soldering at the factory). The 150 also needs a factory mod (a 1 microfared 50 v cap installed) which prevents the receive from getting into the transmit causing flutter. Don't take your unit into a CB shop unless they are highly qualified. Best to return to the warranty station (no charge except for one way shipping). No other problems that we are aware of. Great value for the buck.

I had the same problem when I had the radio set down to 2 watts. When I turned it up to 5 watts on low the problem went away never to return.

Sounds like the finals are tore up, maybe 1 of the dual finals is working and the high power side is out. You said it puts out just 2 watts and that is what it would put out on low side. Do you especially break-up after it warms up a little. If it works better cold and when it warms up then your finals might be shot.

With having 215 55r16 in the front and 215 60r16 in the back is that going to cause a loud humming noise?

Tires with a more aggressive tread pattern will transmit more road noise, 215 60r16 has a greater outside dia than 215 55r16, which means the front tires will rotate slightly faster than the rear, apart from road noise there is a possibility of setting an ABS code over time, or if your vehicle has AWD it could wreck your transfer case, you should never mix tire sizes for road use, hope this helps.

My radio transmits fine. Until recently it received fine. Now it transmits but it does not receive. I've played with the squelch and volume. No luck. Can you advise.

Your finals are fried. Take it to a shop and they will fix the finals. Before you do that be sure to put in an extension speaker just to be sure. Most CB shops are inexpensive.
