The ARRL just filed a Petition with the FCC looking to change how amatuers uses its 60-meter allocation. You can see it at:
Some of the changes will be beneficial.
The Petition goes into great detail about the NTIA concerns about federal users being able to break into amateur communications on 60-meters in order to reclaim any specific channel.
The Petition describes negotiations with the NTIA to change operating requirements such that ONLY VOX operation will be allowed on SSB so that conversations can be broken into easily.
But the Petition also requests the authorization to use Pactor III on the channels. It addresses NOWHERE in the Petition, however, how federal users wishing to reclaim the channel as a primary user will be able to break into the Pactor III transmission.
In Paragraph 8 of the Petition the ARRL also classes Pactor III as a NARROWBAND emission.
As amateurs which are regulated by the FCC, we should all be concerned by what is being requested of the FCC. We should all be concerned whether the results will ultimately reflect positively on our service or whether it will reflect negatively.
If you are concerned, as I am, that using Pactor III on these 60-meter channels will prevent federal users from asserting their Primary user status, you should watch for the issuance of an NPRM on this subject by the FCC and provide any comments you feel are approriate.
"The Petition goes into great detail about the NTIA concerns about federal users being able to break into amateur communications on 60-meters in order to reclaim any specific channel".
This is how it SHOULD be.
Remember. The government OWNS the spectrum, not us. We, as hams, only have a LICENSE to use these frequencies, NOT a deed of ownership.
No one as mentioned, what if pactor is allowed on these channels, once it starts then we will be unlikely to be able to get on these channels with voice, we would have the same problem as the govt. The pactor III users would probably end up taking over these frequencies..
What happens when the pactor robot stations fire up....just a thought.

Pactor III...a *narrow* bandwidth mode?
I don't *think* so!
60 meters CW.......YES
60 meters PSK31...YES!
60 meters USB...well...ok...
60 meters Pactor III... NO!
What will those guys in Newington try next !?
What will they think of next? #How about ARRL royalty fees for using ARRLMail on HF amateur bands......

By not asking for Pactor I and Pactor II as well, didn't the ARRL miss something? #They are different modes, so, how can just Pactor III be used? #Does someone else now make Pactor III-only modems? #I don't think so...... #SCS wants it all for themselves.
Also, how's some poor fed SSB user going to break into a high speed wideband burping session? #I would be willing to bet that speakers aren't on to avoid the unwelcome noise. #So, good luck getting a Pactor/Winlink email exchange to move somewhere else.
Burp-OX isn't quite the same as VOX.
Where's K4CJX when we need him?
Also, Bonnie, KQ6XA said that this is a *wonderful* piece of work. #My, my. #But Bonnie, it didn't say anything about ALE.......
Just another example of the Amateur Internet LIDS in Newington and their master plan.

Why not put together a few facts and post them here like the bandwidth for each mode, occupancy/saturation rates,
Be nice to have a picture of each mode on a spectrum analyzer. Perhaps a Pactor III signal next to one of the narrowband signals.
We could all study the info and post informed comments.
P.S. One of the common arguments is that Pactor III users would carry more information per kHz than other modes. Seems to me the claimed 100baud represents a quantifiable data transfer rate. We should be able to calculate overhead and see exactly what the WPM is for this.
They will try anything to hold on to their part of the financial PIE that is made up of

PACTOR III has a bandwidth of 2.4 KHz, like a trim SSB voice signal- which makes sense, because of the designed usage within the passband of ham transceivers on HF. This is far less than the 'wideband' SSB people use or of course AM (I like the AM nets, BTW).
The key is that PACTOR is superb for passing message TFC VERY quickly, with little power, provides 'instant QSL' of received tfc etc. I often do PACTOR I, II or III with my little FT-817 - generally at 2 1/2 watts, though I can run full power at 5 watts, but that's rarely enough to make any difference. This is for both remote manpack and for use on my little coastal cruiser. I sign ON, pass traffic (TFC) then sign-off in under two minutes - generally. If there is weather information, it may take another minute or two. PACTOR III is just that fast, so it's off the air rapidly. Significantly less than a voice roll call with NO traffic exchanged.
This robustness is essential for EmComm under 'Katrina' like conditions where lists of refugees, next of kin, contact information and other details like location must be passed rapidly and reliably with data/printed record. #This CAN be done in voice, but it's very tedious and slow often inaccurate on voice nets, as we all know. This is one reason that remote missionaries, explorers, blue water cruisers use PACTOR. It's consumes little power and less time than anything else I know of. #
I love CW, but PACTOR is simply the most effective method I know of for passing message traffic - available to hams.
It's the best for supporting most agencies as well, because every emergency responder knows how to use e-mail, and we Hams can provide that to them when infrastructure is down. We do not tie their hands, having them fill out message forms etc., and only sending sending brief text only memos, instead Hams get them communicating with text, maps, and images often fused into single Word documents, as they do every day. We hams can do that for them (and ourselves) with PACTOR. Believe me, it impresses them greatly when we do an EmComm demo out of a self contained station in my rucksack, supporting their comms in a form they're familiar with: "e-mail", but Hams do not require phones, satellites or other commercial infrastructure. #They DO notice - especially now.
If 2.4KHz voice bandwidth is defined "narrowband" then so is 2.4KHz anything else - including PACTOR.
I think members from the ARRL staff monitor and comment on this site. PLEEEEASE step up and explain
how you have classified Pactor III as narrowband.
Must be the same person that invented the term
semi-automatic operation that magically allow
automated stations to run anywhere. If someone
wants to run ECOMM on the 5Meg Frequencies let them
Join MARS or another service that has primary authourization for that segment. Pactor has a purpose and a place but with only 5 channels for Hams in the 5Mhz. This is not it.
