I have an old Icom A-5 aviation handheld with a frequency range of 118.000-136.975 MHz on top of WX, AM, and FM receive functions. Is there any way with little modification, or a simple static build that I can shift my frequency range to encompass marine radio? Specifically from the 156.050-157.425 Mhz range. I am looking to use it to listen in on my local airports, but would like the option to listen to my local port operations, and talk to friends at my sailing club from home if i can push the transmit range that far.
Edit: thanks for all the helpful responses, I have decided to build a Yagi for the avband, to continue listening, and I am taking my technician test tomorrow. I know how important it is not to transmit on avband, I am a student pilot, and my dad gave me the radio. I am getting a UV-5R to use once I get my callsign.
