What is the difference between the F3400D and the F4400D series? 

The F3400D operates on VHF frequencies (136-174 MHz), which are ideal for wide-open outdoor spaces, agriculture, and marine environments.

Is this radio compatible with my older analog radios?

Yes. This entire series supports analog/digital mixed-mode operation. It can detect whether an incoming call is analog or digital and automatically respond in the same format, making it the perfect radio for migrating your fleet to digital over time.

Does this radio come with programming software?

Yes! When you purchase an Icom F3400D or F4400D Series radio from us, we include the official Icom Customer Programming Software (CPS) with your order at no extra cost. (Please note: While the software is included, you will still need the correct Icom OPC2338 Programming Cable to physically connect the radio to your computer).

Yes! The built-in Bluetooth module supports hands-free audio operation with compatible third-party wireless headsets.
