Re: VHF antenna issues?
It's a long shot, and depends on which channels you used to compare with the handheld, but if that "new" radio is just new to you, check that the U/I/C (US/International/Canada) setting is correct. There are some channels which are used as duplex pairs in some locales, and simplex in others. US/Can differ in some, and US/Int'l in more.
