Baofeng UV-5R UV5R, GT3, BFF8, F8HP, etc 'Opening Up' the Frequency Range |
 |
|
The original UV-5R covers 136-174 (VHF) / 400-520 MHz (UHF) |
|
Software Support (OEM and CHIRP) |
| Software does not determine the radios operating capability. This is determined by the radio's Firmware and internal filtering. |
|
'Opening Up' the radio with a Software Hack |
|
There is software available that will allow you to enter
any frequency from 001 to 999 MHz. The operative word being
'enter'. - Will it show on the Display? Yes - Will it actually work on these frequencies? No The internal filtering will prohibit this. |
|
Signals Received in the 900 MHz Range |
|
These signals are not actually on the frequency shown on
the LCD.
They are images of signals that are much lower in frequency. These are referred to as Harmonics, or multiples of the base frequency. Example: If your display shows a signal on 902.0 MHz, it may actually be a signal on 451.0 MHz. (451.0 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 VHF/UHF UV5R 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 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-5R Dual Band Summary |
| The UV-5R series 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. One such tri-band radio is the UV-5X3 which is specifically designed for 144/220/450 operation. |
