Re: cant transmit out
Not really enough info to help you, but you MUST check the SWR of your antenna system. I've seen many cases where the antenna studs were incorrectly installed, shorting the antennas to ground. Also, make sure the Dynamike control on the CB radio is turned fully clockwise.

If you're still getting loud squelch noise but do not receive on any channel, you must check the RF from the antenna to the audio stage(not included). There must be more than just one RF stage in this radio. Let me know what you find.
I would recommend that you put an swr meter (CLICK HERE) between the radio and the antenna to see if your radio is transmitting anything at all. Also, it will check to see if your radio is correctly matched to your antenna. If your antenna is not matched correctly it will fail to transmit correctly.
Just wondering what type of antenna and Cable are you Using? Also When you press the Microphone do you see the needle on the radio Move? Also if you whistle does the Needle Move? If neither Possibly a bad Microphone. Does your friend Notice a signal when you press the Microphone? If so and no voice is being transmitted again it could be the Mic. Then again it could just be bad Coax Cable. Hope this shed some light.
First off, that radio will not transmit very well anyways. but for just off roading it should suffice. You really should adjust your antenna's both of you. First off this is almost definitely the problem if you can recieve but not send. Also if you use the radio without a properly adjusted antenna it will destroy the radio over time, sometimes instantly. pick up a cheap SWR meter and follow these steps:
Plug the SWR meter into the radio, and the antenna.
Start on channel 1, the meter should have a switch with 2 settings, one for adjustments and one for reading. Key up (hold down talk button on mic) with the switch in adjust mode and adjust the knob until it reaches the adjustment marker.
flip the switch to reading and key up again.
Your goal is to get this reading as close to 1.1 as possible, anything above a 2.0 will damage your radio.
if the reading is within range repeat for channels 20 and 40.
Several things can cause poor reception. I have a few questions for you.
1. Have you tried measuring your SWR (standing wave ratio)? This helps give you an idea how well your transmission line and antenna are working.
2. Is this radio being used as a base or mobile? Do you have proper grounding on the antenna?
3. Pressing the mic button and seeing the radio indicate "transmit" does not always mean you are transmitting at full rated power. Have you tried transmitting through a wattmetter into a dummy load?
4. If the transmission line is good and the antenna is good, then I would suspect that something may be wrond with the receiver's front-end (sensitivity).
Receiver sensitivity can be checked by using a RF signal generator. Unfortunately you'll have to take the unit to a repair shop to have that checked. Try the other things I mentioned above. Let me know what you find and we'll go from there.
