High Speed Packet Kits?
Are there any high speed (128 or 256kb) packet kits (PCB +
hardware/components) available for the 70cm or 23cm bands? Would need a full kit including the radio and digital section so I can plug the computer in one end and the antenna in the other. I have searched the web and can't find anyone selling these things for a reasonable price. |

Iwas after a reasonable price. As far as I can determine for these you have to buy the radios and modems separately and 2 of each would cost $4,500 Australian even as Kits. It would be both simpler and cheaper just to get two Icom ID-1s at $4,400 for the two and plug them straight in. One of the mail reasons I was asking about kits was to find a less expensive alternative. Michael |

Do you know where I can get suitable radios from? |

I have used this company's 900 MHz products (115.2 kbps) with great success. There are less expensive equivalent alternatives available, but these are reliable and meet their own specifications. I see they are now advertising 1.3 GHz products for "military", but presume they would have no qualms about selling them. You'll have to request a price quote. The 900 MHz stuff is reasonable, but not cheap. Don't know about the 1.3 GHz stuff. http://www.freewave.com/ |

You'll get better performance on the air with FlexNet, and performance is the desired factor, eh? Running the AX25 stuff in Linux gives you the latest in packet radio from the mid 1980's. Things have significantly improved since then, and it would be a shame to see you spend good money on equipment and then cut your own throat by going cheap on the software. Charles, N5PVL |

Can you provide a link to the specification for the FlexNet routing protocol? Is there support for Kantronics TNCs? -- ... Hank http://horedson.home.att.net http://w0rli.home.att.net |

These appear to be in the ISM (licence free) band -not high speed amateur packet radios - and are limited in their power output. In Australia at 900MHz our limit is 1W ERP. I priced the 900MHz ones from the Australian disributer and they were $1600 for the serial version or $2800 for the ethernet version. I wonder how much they are in the US? |

Charles, N5PVL I had a bit of a go with FlexNet a couple of years ago. I don't know what its like now but back then it was a DOS application for a windows machine. It would not run properly on a protected machine (I was mainly using NT4 at the time - now I only have XP or linux). I did manage to get it going on a windows 95 or 98 machine but could not manage to figure out how to get it to work properly. |

A different product from http://www.omnispread.com using DSSS and approved for use down in your area might also fit your needs (LAWNII) They claim that these radios can work over 10 kilometers (6 miles) using 20mW output with a receive sensitivity of -95dBm. I wonder if that is realistic. The more expensive ones transmit 1W. |
