Is anybody using PSK31 or SSTV or other digital modes on 11 meters in the USA?? I have heard SSTV and packet signals from Europe when the band is open. This sounds like fun and the equipment isn't expensive. Any comments. |

I have used packet on 11m quite a bit. In fact, a few years ago, we had quite a group going, using modified Midland 13-882 radios and old kantronics tnc. Very cheap way to play! |

packet radio is basically using a type of modem called a "tnc" or terminal node controller, hooked up to the mic and speaker audio, plus transmit key. The tnc is generally controlled through a computer serial port, using any number of software terminal programs, even Windows HyperTerminal will work, or alternately, you can pick up an old hardware terminal like the TRS Model 100 or any dumb terminal to control it and get text output on your screen. In essence, its like doing a internet chatroom over the radio, but with some other functions as well. There are also some software tnc programs out there like BayCom, which are cheap and run on any old pc. This stuff can be found on EBAY or by searching the internet. |

Thanks for posting. I think I'll be on the lookout for a TNC at the hamfests this summer and looking at shareware for running SSTV.It is cool thinking of the possibilties of packet on 11 from nodes and digi-peters to mail. Fun Fun Fun !! |

Running packet on 11 meters is not legal in the United States. |

And, technically, neither are many of the concepts espoused here. So what? Do you think that an occasional blurp of digital data is any more obtrusive on the band than roger beeps or other "toys"? Do you ever break the speed limit?
I bet you are not "WorldWide" with a stock CB radio and output. |

Since I've been monitoring 11 meters, I have noticed a significant increase in digital activity. Much of it is in the government portions of the 'freeband' areas, which I understand is mostly military. I wonder each time I run into a digital signal if it is a hobbyist or one of the legitimate users?
There is one sound in particular, which is hard to describe, but it sounds like a harsh buzzsaw sound that changes tone. It seems to be most active around 27.800-27.990, but I hear it elsewhere, too. It is really loud. I think this might be military in origin, but I'm not sure. It is definately not packet radio like is used in 2 meter--I know what that sounds like. This thing is MUCH harsher sounding. Anyone know what I'm talking about? |

I think I read somewhere that is military or scientific propagation testing. Does anybody remember the "Woodpecker"? Same sort of deal. |
