Possibly an antenna problem. Check your antenna set up. Be certain all connections are tight, and there is no damage or smashed places in your coax. Also check to see you are using the correct antenna for your frequency bandsplit. Depending on the type of antenna your antenna may need to be trimmed to a specific length. Look at the coil at the base of the antenna (black dixie cup shaped device). Check it for corrosion. Shake it, if it rattles, replace it.

Swap your radio with another vehicle's radio and see if the problem stays with the radio. If so, your radio needs service.

Best regards.

I have a icom ic-v8000 not transmitting or receving there is no short voltage everything looks perfect. when you key the hand held microphone all you hear is tweet,tweet, tweet......


The IC-V8000 is a high power (75 watts) 2 metre radio, it will draw about 15 amps on transmit. Also you might want to make sure your antenna SWR is low about 1.5:1. If you are not receiving anything at all I suspect you may have an antenna issue and this will also effect your transmit as well as the radio will protect its self by reducing the output to almost nothing if the antenna has a high SWR. If you don't have an antenna analyzer check with another amateur radio operator they may know someone who does. Your local amateur radio club most likely will have someone who help you solving your antenna problem.

My icom v8000 says off when I transmit how do I fix this


Hi
This sounds very much to me like a power supply problem.
If I understand your question correctly, the radio will turn on but when transmitting it shuts itself shuts off. This is usually caused by a poor connection to your battery. Although it is possible to show 12v using a voltmeter, there may not be enough connection when putting the circuit under load. (25 watts is a considerable load)

I would inspect both positive and negative connections (pay particular attention to the crimped lugs) , clean and lubricate them and give it another shot.

Here is a link to Trojan battery explaining in detail the importance of clean battery terminals.

Hope this helps you out.
-Steve

Check the input output settings.
the baofeng is notorious for being somewhat difficult to program manually.
Try the software setup if possible.

Display says OFF


You are on a portion of the 2 meter band that the radio does not allow you to transmit on. You need to get within the legal band portion and transmit there. The IC-V8000 only transmits between 144.000mHz and 148.000mHz. You likely have the radio outside of that range.

A buzz accompanies transmission


Hi Richard

This is nearly ALWAYS caused by (A) A poor connection with cabling that is too small or long for the amp draw when transmitting, or (B) Low battery voltage or alternator output.

I'd check the power and ground cables first, and use a cable gauge at LEAST one size bigger.
Good luck!
