TalkbackOff air communications via walkie-talkie (portable) and base station.
The frequencies listed for talkback are mostly in pairs. This is because they are designed for duplex (Base Tx/Rx, Portable Tx/Rx) operation. For simplex use either half of the pair can be used; continuous transmit (base half) or press-to-talk (portable half).
Standard powers are 5W base and 1W portable for outdoor use, 1 W base and 100mW portable for indoor use.
Standard bandwidth is 12.5kHz.
Assignments are calculated and issued on the basis that the radio equipment is manufactured and used in conformity with the UK Interface Requirement IR 2038, this requires the use of Isolators (circulators).
Doesn't match up?
If your kit isn't tuned to the frequencies suggested you may still be able use it.
Check Your Frequencies to see if we can licence it at the power, bandwidth and location you require.
If you use our recommended channels licensing should be quicker and we are more likely to meet your requirements. You will also be able to book online.
