How to update your UV-3R Mark II to support 220mhz Ham Band

Some models of the radio are able to support a much broader
range of frequencies if you store a special memory file into
the radio.

Follow these steps:

[1] Install UV-X4 v1.11 programming software

[2] Run the UV-3R-soft-Modder program to update your UX-X4 software
to add some extended Band Plans

[3] If you have an existing memory file, re-run the soft-mod program to
change the Band Plan that is embedded inside the .3R memory file.

[4] Load the memory file inside UV-X4 and write the memories to your radio 
and your radio will now have 220mhz added to your radio!


Tech TIP #1:  If you are unable to write a memory file to your radio,
power-on while holding down the VOL button. It will reset your
radio back to factory and you will be able to write the extended
frequency file.

Tech Tip #2:  2 memory files are included.  
Both files have 220mhz included but during tests with other hams, we found
that my radio gave better 220mhz results if we lowered the UHF instead of 
raising the VHF frequency range.  I suggest testing both methods with your
radio to verify results.

"VE3PZR UV-3R 220mhz Extended 115-199 200-529.3R"
"VE3PZR UV-3R 220mhz Extended 136-235 400-529.3R"

I hope it works for you, it worked for me!
