I do have a valid extra class license. There are lots of hams who use CW and SSB on the VHF bands and want protection from FM repeaters and other wide-band signals. The bottom 300 kHz of each VHF band should be protected. I was a member of WSWSS and the San Bernardino Microwave Society and partcipated in most 10 meter, VHF, UHF and microwave contests between 1993 and 2001.
There should also be spectrum for wide-band modes. I used amateur satellites which had 50 kHz wide HF downlinks and 200 kHz wide VHF and UHF downlinks. There should also a be a place for wideband terrestrial modes. For some reason there is a 20 kHz bandwidth limit on the HF bands for data but not voice or image transmission. Bandwidth limits should be the same regardless of content as anyone with a computer can mix voice, data and images indiscriminantly. There is certainly space on the 6 meter band for wideband data that exists in the band plans. If you look at the spectrum allocated to repeaters on a spectum analyzer, there is even more space if we had more intelligent methods of spectrum allocation and sharing. The spectrum between 50 and 450 MHz is useful because path losses are low and omnidirectional antennas allow mobile operation and the operation of nets over wide areas. The 20 kHz bandwdth limit on VHF data transmission is antiquated and if you can radiate a 9 MHz wide ATV signal on the 70cm band the same bandwidth should also be available for data. 73, John KD6OZH ----- Original Message ----- From: bruce mallon To: digitalradio@yahoogroups.com Cc: [EMAIL PROTECTED] Sent: Saturday, December 29, 2007 13:19 UTC Subject: Re: [digitalradio] Ham Radio ALE High Frequency Network (Re: FCC to Kill Digital Radio?)

This provides protection for weak-signal enthusiasts. Wide-band segments should allow 200 kHz maximum bandwidth between 29 and 225 MHz. WHAT PROTECTION FOR WHO ?????? EXPLAIN THIS ? WHO WOULD BE PROTECTED ????? Some digi moron who would sit on 29.600?, 50.125? or 144.200 ? Here we go again 90% of those bands for 1% of all hams ..... Do you think anymore than the analog morons that sit on calling frequencies and destroy them for all others that adding digital would help weak signal work? Do you think 200 kHz wide signals on bands under 2 MHz or 4 MHz wide is a good use of BAND SPACE? Lets not go there with you will not even hear the " RISE IN BACK GROUND NOISE" power has to go SOMEWHERE ..... and if legal they could not be stopped. How come no one has address my posting about the many MHz of UNUSED space above 219 that you already have? We as non digital users have right too and no where do I see any protections for existing users only placing non compatible mods on already well used bands while UNUSED bands sit empty. Bruce Like D-Star ( DEATH-STAR ) demanding repeater pairs here in Florida with ZERO usage of the 3 here in tampabay how crowed is 223 and 440 MHz are you out of room? __________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!
