# Communications Systems

The MH60’s communication system is equipped with dual radios, allowing independent operation of **COMM 1** and **COMM 2** channels. In the current MSFS implementation, the system is limited to supporting only **standard VHF/UHF COMM frequencies** as defined by the simulator. This means the radios cannot tune to NAV, HF, or encrypted channels.

The COMM Radios are operated with the Keyset, via the TUNE and COMM menu/popup. For more information omn the keyset, refer to [keyset](https://docs.miltechsimulations.com/miltech-simulations-mh60/aircraft-and-systems/aircraft-displays/keyset "mention")

## Entering COMM Frequencies, XFER 

1. Use the quick TUNE access from the Keyset Menu, or TUNE button on the Keyset keyboard, to access the TUNE Pop-up on Mission Display.
2. Use PG UP or PG DN, either on the Keyset or MD Bezel, to select a radio to tune. Remember, anytime you see a white box highlighted WHITE, it is a cursor that may be interacted with PG UP/DN/LEFT/RIGHT. 
3. Once selected, press ACK or SEL (MD Bezel or Keyset) to enter a frequency. 
   1. The STBY FREQ will now appear with a green background, indicating that the field is now active and ready to receive input.
   2. Use the Keyset numberpad to enter frequency. The decimal period is added automatically.

4. Once completed, press ACK again to validate and change frequency. If the entered frequency is invalid, frequency will not be changed.&#x20;
5. Alternatively, you may press ENT to directly validate the frequency and XFER to Active. You may also use ENT at any time while the TUNE Pop-up is open to XFER the frequencies selected.

Alternatively, you may access V-UHF1 and V-UHF2 from COMM Menu, V/U1 and V/U2 respectively.

XFER is always available under COMM Menu without requiring TUNE Pop-up to be opened. &#x20;
