I have tested it at 435MHz, I found its sensitivity is better then 12dB SINAD, without adjust any parts. We can find two model of VISAR radio, which frequency range is 136-178 MHz and 403-470 MHz. I have tried to adjust the output by VISAR RSS software, it can give higher output then its Technical Specifications. There is only new model Japanese portable radio with MOS-FET RF parts can output such power at 7.2V. VISAR give us high power output at 7.2V, the VHF model VISAR can output 5W and UHF model VISAR can output 4W. So MOTOROLA say “The VISAR portable radio is more powerful than radios twice its size.? VISAR is a very small MOTOROLA radio set, it is even smaller then any Japanese portable radio, it looks like a FRS radio, it can easily put into pocket, but its performance is as well as other MOTOROLA professional radio, for example MOTOROLA HT1000.
