Cybernet 134 chassis (upper tier version)

This was a repair with no RX audio...dufff capacitor.


Mr Chippie drove along our usual 6-mile test route, the 'wrong side' of a hill. He stopped at the five mile point to test this set as a low power static test. The radio was set for 4.0W for full power & 0.4W (400mW) for low power. Our own standard replacementl mike was used throughout. At the end, the factory original mike was demonstrated through to our base station.


Our continued thanks to Thunderpole for kindly supplying the T3000 radio (and new mike) which is fitted to the test vehicle at no cost to us. This is the sole reason for the 'paid promotion' marker on this video.
