Re: Designing Maritime Radio #bitx40

Hi Qonita,

This sounds like a good project, most of what you are doing will involve programming. Hardware wise you’ll need to setup the output filters as either lowpass or bandpass. All Maritime and commercial services use Upper Sideband (USB) and they are also channelized. You will need to set your mode to USB and you could setup the encoder as a rit/clarifier. If you are in need of more than one channel the encoder switch can be used to change or step through channels. Also you could program the display to readout the channel number and frequency. This would streamline your code a lot and maybe leave room for decode program for the GPS position stream and DSC functions. 

Have fun with it and let us know how it goes.
