Russell, please see my comments below. I have added them after the ARRL's comments. This is just my viewpoint.
- The frequency 5368.0 kHz (carrier frequency 5366.5 kHz) is withdrawn and a new frequency of 5358.5 kHz (carrier frequency 5357.0 kHz) is authorized.. K3UK comment= As of March 5th 2012 USA hams should not use 5368 and but instead use 5385.5 along with the four other authorized channels.
- The effective radiated power limit in the 60 meter band is raised by 3 dB, from 50 W PEP to 100 W PEP, relative to a half-wave dipole. If another type of antenna is used, the station licensee must maintain a record of either the antenna manufacturer’s data on the antenna gain or calculations of the antenna gain. K3UK Comment: if you have a half-wave dipole as of March 5yh you can use up to 100 watts PEP. If you use another antenna with some gain over a dipole, you must know the gain of your antenna and do some calculations to make sure you do not exceed 100 watts PEP. You need to keep a record in your shack of how you arrived at these calculation just in case the FCC receives complaints that you are exceeding the limit and investigates your station.
- Three additional emission types are authorized. Data (emission designator 2K80J2D, for example, PACTOR-III), RTTY (emission designator 60H0J2B, for example, PSK31) and CW (150HA1A, i.e. Morse telegraphy by means of on-off keying). For CW, the carrier frequency must be set to the center frequency. For data and RTTY the requirement to transmit “only on the five center frequencies specified” may be met by using the same practice as on USB, i.e. by setting the suppressed carrier frequency of the USB transmitter used to generate the J2D or J2B emission to the carrier frequency that is 1.5 kHz below the center frequency. K3UK comment. As of March 5 2012 you can use the same digital modes that are authorized on other HF bands.. PSk31, PSK63-250, Olivia, MFSK16, RTTY,, JT65A, Opera, Throb, ALE 400, Contestia, MT63, Packet, Pactor, etc, etc. You can also use Morse code. For digital modes and CW you need to make sure you are centered on the channel correctly..
- Automatic control on data and RTTY is not permitted; a control
operator must be in a position to exercise either local or remote
control over the transmitter. K3UK comment: . I'm not expert on this but I take it to imply that you can operate things like ALE, Winmor, Winlink 2000 along with other digital modes as long as you are in the shack or are monitoring via otehr means and can shit the station down if there is a need to.
- The FCC noted that “amateur operators must exercise care to limit the length of transmissions so as to avoid causing harmful interference to Federal stations.” This is a very important caveat: If a Federal station requires amateurs to cease using a frequency, the amateur station must be able to do so without delay. K3Uk Comment. Already on 60M, hams appear to cease if they hear signs of a primary services operating on or near the channel. They do not wait for the primary services to ask hams to cease. You hear comments from hams like "I hear another user of the frequency, will be back when they finish".
- it appears that any J2D data emission is to be permitted up to a
bandwidth of 2.8 kHz, provided that care is exercised to limit the
length of transmissions.K3UK comment. The fact that 60M is a band shared by other services that have priority over amateurs means that we should keep the length of transmissions in mind. For example if there was a WL2K sever there and you connected to the server to send a very large file that could take 20 minutes to complete, you maight accidentally cause interference to a Govt station on the same channel. Similarly, if you ran PSKmail on that channel. Common sense would suggest that you run modes where there is a break in transmission avery minute or so. Then if you hear the channel in use, you would stop. QRSs modes may not be the best for this band.. Something like Opera would be fine (if attended) and u had the CW Keying set up so you can listen between transmission bursts.
... How does one know if it is a Federal station or another ham using a mode one doesn t copy? If someone hears high speed CW that they can t copy, how doMessage 1 of 6 , Feb 4, 2012View SourceOn Feb 4, 2012, at 4:39 AM, Andrew O'Brien wrote:How does one know if it is a "Federal station" or another ham using a mode one doesn't copy?

They could be copying a station that we can't hear.I know that a lot of hams are excited about the new rules but I think we have gone from a limit usage band (ssb) to a real mess that will significantly reduce the value of the 60m allocation. Rather than expanding the usefullness, I suspect it will turn out to be more like the mess with the usage conflicts on 160.Ken WA8JXM
