Pickup a cell phone, dial, and talk. There's no magic in that. I remember making telephone calls to other countries when I was a little kid in the 60's. The Transatlantic cable was laid in the mid 19th century. People could talk a long way away then too. Worldwide communications pre-dates radio communications. It's a matter of infrastructure. I think I will drop my oar into this one too. Being able to call someone in China is not the same thing as calling out, and getting a response from someone in China. A.G. Bell's practical invention of telephony long preceded practical (or even impractical) radiotelephony and no one seemed to care, but many got excited. And to invert the argument. When I lived in Europe in the late 50s early 60s, Paris had such a funky telephone system that reportedly you could dial a "special number" that put you into an open common trunk where others would have been already deep in spontaneous conversation. It was very popular and "exciting...." until they fixed it (in their own time, of course - for the French that could have been many years later). 73's Richard Clark, KB7QHC |

I don't want to comment on the legal part of the puzzle (because I already have a headache). However, it should be obvious that there's a potential conflict between unlicensed Part 15 operation, and licensed part 97 operation on 2.4GHz. Place your bets and blast a way with kilowatts on 2.4Ghz. Will 800,000 licensed US hams prevail over perhaps 300 million unlicensed wireless devices? Want to bet on who will win before an FCC tribunal? If there is a conflict, I'll place my bets on Part 15. Hint: When dealing with the FCC, don't ask any questions for which you don't already know the answer. It's highly likely that you'll get a very weird and undesireable answer that you don't really want to hear. -- # Jeff Liebermann 150 Felker St #D Santa Cruz CA 95060 # 831-336-2558 # http://802.11junk.com # http://www.LearnByDestroying.com AE6KS |

![]() Why not go find a couple of el cheapo PRS handi-talkies (Personal Radio Service - 450 plus MHz) and let the kiddies talk to each other that way? Why bring ham radio into it at all? It was by way of introducing them to our hobby in the course of giving a lesson. That's all. Thanks for your input. "Sal" |

*Check with
your club and find a woman operator to respond to the CQ. *Smaller children will respond better to a woman's voice. -- Tom Horne Ah -- good idea. It will be out of my home area, but I'll bet if I scouted around after I get there, I'll be able to find someone. Thanks. |

Since 2.4 GHz is basically line of sight, few hams work 2.4 GHz, and the Part 15 devices running under Part 15 can hop to other frequencies including frequencies outside the ham bands, I don't see a lot of potential for conflicts. -- Jim Pennino Remove .spam.sux to reply. |

![]() Nobody was interested in Morse Code until I mentioned that it could be used for "secret communications". *That means that the parents and teachers couldn't understand what the kids were saying. *Lots of interest (and potential problems) there. The problem with todays version of ham radio is that it's really boring. *Nobody wants to talk to someone around the world, when they can pickup a POTS or cell phone and do it with much less effort and expense. *With the demise of Heathkit, building radios is no longer a draw. *The magic of radio is gone. * I have a diverse collection of demonstrations for them, hoping to catch each one of them with something they find interesting. I have a handout with eight Morse Code characters on it, enough to spell out some easy words, They're mostly 4th graders. I'm doing magnetism and communications and showing how they relate. I taught school in the Navy, but I have no experience with little kids, except my own. My Navy students were almost always well-motivated but I have no idea what the 4th graders are going to be like. They are all in the Gifted And Talented Education program and I think it's either going to be great or awful -- no in-between. |

Seems to me that "KD6VKW Portable 1" and *and "KD6VKW Portable 2" would be appropriate. *The addition of arbitrary letters and or numbers after your call sign could be misconstrued as meaning something other than what you intend. *The use of Portable 1, Portable 2, etc., is more straightforward and accurately describes the type of conversation in progress. * I thought of that but the numbers would seem to imply geography, like when I was in Colorado in the summer, I signed "Portable 0." Thanks for the suggestion. |
