You watch this video and check your power output specially on those channel at chich not transmitting, if there is no power at those channel it mean that you program out of range radio band frequency, so you check your frequency and correct it.

It is very likely that the reverse polarity diode inside the radio is shorted, usually because the radio was connected up incorrectly.

Generally the higher your mic gain is set, the higher the modulation level. You want to avoid splatter by not setting the mic gain too high.

' Move the antenna angled forward ' Freightliner cascadias have powered driver and pass windows plus a thermostat inside the mirror arm ,The motors and electrical wires produce a EMF bubble that will disfigure the RF and absorb the energy. If you mounted the antenna to the mirrors arm with a bracket, just keep pushing it forward untill it passes the test.

I have the same walkie talkies and on mine I can hold down the mode/lock button and it will come off of the Rx mode. Also, you should be able to press the talk button and it will come off of the Rx mode.

Most likely, you have no 'voice' signal coming from the microphone. The MODulation control did not turn itself.
Check for signal from the shielded or white wire from the mike.
A capacitor could have shorted in the modulation limiter circuit, limiting the modulation to 0%.

10 of what looks like AA NiCads. Open the cover and look.

Nickel Cadmium (NiCad) Batteries:
Batteries with 700 mAh minimum recommended.
Top Grade NiCad batteries can be ordered direct from Cobra. See page 22 for details.

I am not sure just what is stuck, the button or the switch itself. If it is the button, try swabbing it with a Qtip soaked in Isopropyl alcohol to loosen any grease or dirt that may be causing the problem. You might want to open the case and remove the guts, being careful not to break any wires. If the button can be removed, clean it thoroughly and put the thing back together.

If the switch is shot, then you probably should just purchase another radio. Unless you are a micro surgeon, you probably won't be able to replace the switch yourself. A new radio is less expensive than taking yours to a shop for repair.

What is the swr? This can impact the receiver. However, the tuning coils for receive and transmit are close to each other and someone most likely turned the receive coil instead of the transmit coil. The coils that are adjustable that affect receive are 13, 15 and 3. 3 is the coil that is close to the transmit section. You may want to have it realigned.
