Without looking it up, to be honest the only I "think I know" is 22A for safety info, so that equals "1". Seems like I used to check that leaving Bonfouca Bayou on Ponchartrain. Mostly out of fear that I'd hear them alerting everyone that I was leaving port .
I'll guess 2 = 16 since that is a main channel.
WX2, you're throwing me a curve on,tho. I'd guess that was a weather channel but there's nothing weather specific on the list of choices ?
A new VHF is on the list for EE before next year's planned move back to the coast. Hers was pretty much same vintage as her.
