There was a discussion on this topic a few weekends at the local ham club after-meeting .... all those that don't have to be awake at zero-too-early in the morning to go to work wander over to a local 24 hour coffee shop and discuss all kinds of technical topics.
One comment was that US military would really love to see TV channels 3, 4, 5 and 6 vacated. That drew a bunch of "huh" comments, and some head nodding from others. It seems that 66-88mhz is used by the military in much of the world. In the USA the 60-66MHz range is television channel 3, the 66-72MHz range is TV channel 4, the 72-76MHz frequencies are used as "Operational Fixed / Repeater" frequencies (essentially commercial point-to-point links), 76-82MHz is TV channel 5 and 82-88MHz is TV channel 6. Might want to keep that in mind... lets see how many areas have 3, 4, 5 an 6 freed up. Mike WA6ILQ At 09:10 AM 01/06/08, you wrote: >Reality >Channels 2-13 will mostly be vacant.
