'Opening Up' the Frequency Range

 
June 2015
Revised 2020

 
For reference:
     The 136-174 MHz range = 150
     The 220-260 MHz range = 220
     The 400-520 MHz range = 450
 
 
 
Software Support   (OEM and CHIRP)
 
Both CHIRP and OEM Software can be used to program the UV82 series, however, software does not determine the radios operating capability. It is the internal design and filtering or the radio.

A radio specifically designed for 150/450 MHz operation cannot be converted to 220 MHz using software alone.

 
'Opening Up' the  radio with a Software Hack
 
There is software available that will allow you to enter any frequency you desire from 001 to 999 MHz. The operative word being  'enter'.

Will it show in the display?       Absolutely
Will it actually work on these frequencies?  No
 
Signals Received in the 900 MHz Range 
 
These signals are not actually on the frequency displayed on the LCD.
They are images of signals that are much lower in frequency.

Example:
What you hear on the displayed frequency of 905.0 MHz may actually be a signal on 452.5 MHz. (452.5 x 2).  A signal heard on 948.0 MHz may actually be 158 MHz x 6.

Can these signals be heard?   Yes
Are they actually transmitting on that displayed frequency?   No
 
Tested Frequency Range
Bench Test Results 

 
Bench testing has shown the actual transmit range of an expanded 150/450 MHz UV-82 to be:

   VHF range 136-174 MHz  expands to  128-176 MHz
   UHF range 400-520 MHz  expands to  384-524 MHz

Outside of the above range, the radio would either not transmit or was unstable.
Receiver coverage drops off sharply to zero outside the factory specified range.
 
My Radio is Locked Up.
It will no longer transmit.
 
Go to the RECOVERY section of Miklor.  
This procedure goes beyond a Menu 40 Reset by reinstalling the all internal software back to Day 1 from the factory.

UV-82 as a Tri-Band Radio
Summary
  
The UV-82 is not capable of any reliable operation outside their specified Dual Band frequency range. 

True Tri-Band radios use a totally different method of band pass filtering.


Note 1: UV-82X3
A true Tri-Band radio uses a totally different method of band pass filtering. One such tri-band radio is the UV-82X3 which is designed for 144/220/450 operation.
 
Note 2: UV-82X
Several years ago there was the UV82X which has since been discontinued. This was a dual band 150/220 MHz.
