Magnum S3 talkback and receive fuzzy yet transmit sounds ok except now it only puts out 30 watt from 85.
It sounds like you are experiencing an issue with the audio quality on your Magnum S3 radio, specifically with the talkback and receive audio being fuzzy. Additionally, you've noticed a decrease in the radio output power from 85 watts to 30 watts.
Here are a few things you can try to troubleshoot this issue:
- Check the microphone and the audio cables for any damage or loose connections.
- Check the radio's settings to ensure that the microphone gain and audio levels are set correctly.
- Check the SWR (Standing Wave Ratio) and adjust the antenna if necessary.
- Make sure that the radio is not in an overdriven state, this can cause distortion and decrease the output power.
- Clean the radio's final transistor, check the cooling, and check that the final transistor is not over heating.
- Check the radio's manual for any information regarding troubleshoot, or if there are any specific instructions for audio settings and power output.
If none of these steps resolve the issue, it may be a problem with the radio itself and you may need to take your radio to a professional for further assistance.
