A duplex channel utilizes a duplex repeater. A repeater is basically a tower that receives your
transmission and then sends it like a rocket further along. This allows your transmissions to
travel much farther. A duplex repeater both transmits transmissions and receives transmissions at
the same time.
If you want to use a duplex repeater you must set up your radio to both transmit and receive on
different frequencies while on the same memory channel within your radio. In other words, if
you’ve set up Channel 7 as a duplex channel, you have to be able to utilize your Channel 7 to
transmit and receive at the same time.
Duplex repeaters require a very specific frequency for messages to be “input” and processed by
the repeater. They then transmit this same message and a slightly different output frequency.
Think of these input frequencies as something akin to a hidden door. If you can find the hidden
door, you can enter it and use what’s inside.
You can often find what the “input” frequencies are for the duplex repeaters within your
geography by searching online, utilizing the app
, or by talking with other HAMS
in your area. Some duplex receivers you won’t be legally permitted to use, so figure that out first.
Once you find what the input frequency is, and if you determine you can legally use the
duplex repeater in your area, here is how you program your UV-5R to use it:
•
Turn the radio to Frequency Mode by hitting the “VFO/MR” key.
•
Enter the output frequency of the duplex receiver you are trying to reach by using the numerical
keypad or the down and up arrows on the face of your radio.
•
Press the “MENU” key to confirm your frequency decision.
•
Hit the “2” key followed by the “6” key. This will take you to frequency offset.
•
Press “MENU” to select such.
•
Use the up and down arrows/numerical keypad to enter the specified frequency offset for the duplex
repeater you are programming for.
•
Once you find such, hit “ENTER” to save your choice.
•
Then hit the “2” key followed by the “5” key to get to the offset direction.
•
The up and down arrows can be used at this point to select for either a positive or a negative offset.
•
Press “MENU” to confirm your decision.
•
Odds are that due to the amount of work involved for such, you’ll want to save all of this as a memory
channel within your UV-5R. To do such, hit the “*/SCAN” key to go into reverse mode, and then save
that to the same memory channel.
•
Hit the “EXIT” key to exit the menu.
If everything worked correctly, you should then be able to utilize the duplex repeater to
broadcast your message even further than you would have been capable of otherwise.
