Yup, the DirecTalk. Didn't see your earlier post or would have advised, only had the phones for a few weeks....

There are something like 10 "channels" with about 15 "privacy codes" plus the ability to monitor in "open" squelch on each channel. Maybe 10 spread spectrum center freqs with 15 spreading codes, not sure. There is also the ability to selectivly call another unit by its PTN or phone number. The manual indicated that this is a private, non monitorable call-implying that a unit monitoring in "open" squelch could not hear the comms. I've yet to test this, just got the third unit yesterday. When I get all 3 together I'll make a selcall and see if the other unit is able to hear it. FRS-ish range is a fair comparison.

That's what I heard, the ideas been banging around for a while, originally it was to construct an entirely seperate network, then came Sprint, now a bit easier...
