VX-1R Software Modifications

With the software described in the post below, you also can extend the recieve and transmit range of your vx-1r transciever without modifying the hardware.

The maximum transmit range is 108-560 Mhz with full output power! It is also known as the Free-Band configuration.

With the Free-Band mod, the recieve range is 76-999 Mhz.

Here is the table of reciever sensitivity as listed in the owners manual:

76-108 MHz 1.6 uV
108-136 MHz 0.5 uV
144-148 MHz 0.16 uV
170-222 MHz 15.8 uV
300-420 MHz 0.5 uV
430-450 MHz 0.18 uV
470-800 MHz 15.8 uV
800-999 MHz 5 uV

As you can see, the vx-1r does not really make a good reciever outside the amateur bands, especially on VHF so you'll need a better antenna to compensate.
