When you folks program your radios with the GMRS/FRS frequencies, do you include a "default" PL encode tone? I have seen some GMRS basic info pages that talk about using encode PL 67.0 on channels 1-14, since if an FRS radio comes preprogrammed with a tone, it is probably 67.0, or Tone 1. Likewise, they also suggest programming encode PL 141.3 for channels 15-22, since (as they argue) this is the defacto PL most used by GMRS users.
For amateur radio work, I never program PL tones for simplex channels, although I see why GMRS users might do so (decode) to keep the FRS blister pack kids out of your receive. I'm just of the mindset that if I can hear it, I want to option to talk to it (or ignore it).
Thoughts?
