'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.
