It sounds like we're in agreement. There is space for wider emissions on the VHF bands. 50.7 Hz is unsed here and designated for experimental use in the band plan. I participated in SSB nets and contests on 50, 144, 222, 432 and 1296 MHz when I lived in southern California and large portions of all these bands were dead most of the time. However, repeater owners have the VHF bands staked out for a lot of closed repeaters that are infrequently used and the band plans reflect this.
I'm aware that most emergency preparedness nets are on 2 meters, but served agencies are looking for more digital capabilities as they use PCs just as much as any commercial business. They'll use whatever frequencies hams provide equipment for. 73, John KD6OZH ----- Original Message ----- From: bruce mallon To: digitalradio@yahoogroups.com Sent: Sunday, December 30, 2007 10:11 UTC Subject: [digitalradio] 220 sits empty AGAIN ..... NO AGENCY USES 6 METERS here in Florida I have been active in New York since the mid 60's and from Tampa bay since 1973 and there has never been any emergency nets on this band only local ones from 52 - 53 MHz. All emergency nets are done on 2 and up. 2 meters is not dead either even SSB has users. I started on AM both on 6 and 2 meters. Even back more than 40 years ago 6 HAS ALWAYS been CW from 50.000 -50.110, SSB from 50.105 - 50.400, and AM ( YES THERE ARE ACTIVE AM STATIONS I work them during band openings )from 50.400- 50.450 and a space used by both ssb and am if the band is really hot up to about 50.600. There is mixed digital like psk-31, rtty packet around 50.600 - 50.700 It has not changed in 40 years but RTTY is now mostly PSK-31 they use the same spot on the band since they don't interfere with each other. Above that a few repeaters above 51 MHz NOW the only space for any mode changes is 50.7 - 51 MHz that back 40 years ago was used by remote control IT IS DEAD no one home If you want a spot this is it otherwise someone using the band since its inception has to move.... ONE BAND OPENING or worse yet open during a contest for thousands of stations to turn it into CB IT IS ALMOST THAT BAD NOW. If you want wide band space for any mode you need to be working on 50.700 - 51.000 or 223-225MHz and up for this. I run a good station on 223-225 MHz and have been active since the mid 70's and within 100 miles of Tampa there are 10 users not hundreds like 50-54 MHz. How come no one has even proposed this for the empty 220 mhz band? Like 10 meters we are at worst conditions right now like 10 we have SMIRK ( 6 meter 10-10 ) has about 8,000 members many active 30 years or more. 70 cm has no users here either just a few low usage repeaters what little ATV died 20 years ago. 70 cm again large band no users not even P-25 or D-Star. If you want space you need to look there those band need more users not 28 or 50 MHz when open they have enough. You will find little opposition. Bruce --- "John B.
