>But old fashioned cell phones like mine can use at least 2 carriers... That's because there is only one analog protocol - AMPS, the original ATT/Bell Labs one! My carrier (Verizon Wireless) has notified us a while back that they will be dropping analog service sometime next spring. When you get into the digital world, there are at least three incompatible protocols - TDMA, CDMA. and GSM. If there are several carriers using the same digital protocol, the chances are that one is leasing spectrum space from one of the three majors (ATT/Cingular, Verizon Wireless, and T-Mobile). >It would seem that there are some other issues Lots and lots of them! >And so apologies to the list for OT >> >> No different from trying to receive AM broadcasts on an FM >> broadcast radio. >Guess you never had an am/fm radio? My Kenwood R-5000 HF communications receiver can decode FM. My Elecraft K2 can't. -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
