Need help diagnosing VHF issue

[McGillicuddy]

If you're hearing others but you're not being heard or only occasionally being heard your PTT (push to talk) switch is failing and must be fixed. I got mine fixed for about $80 at a marine electronics shop only cause the guy had switch on hand. Raymarine will fix yours for $149 flat rate. Seems the 210 had a lot of buttons but I really don't know it's caliber. If it is like the 218, fix it. Otherwise you can get a quality radio for under 2 C-notes now so consider that.

It could also be your antenna, or cable. If you're offshore much, I seriously consider a Shakespeare Galaxy series antenna or a Digital model. They have twice the range of a Centennial model.

Not sure how old your VHF is, but if you gotta spend some money consider an ICOM or Standard Horizon Radio (they have $65 flat rate repairs and have some deals if you shop around).
