Requesting opinions about the old pro433 versus the 125. The pro 433 I recently dug out of the closet, it still works quite well. For aviation would the BC125AT give me a major boost? They would be on a dipole mounted about 30 feet up. I guess I'm asking is it worth the investment. (Marine is also a side interest.) The 433 is a dedicated aviation/marine scanner, I've been trying to trim down scanned frequencies to those more local, not the nationwide ones in the database. Opinions?
