    Yep, it must be your rig that is 50-75 Hz off. Tell that to the FCC when they nab you.

    If he fesses up to only 50-55 Hz, they might reduce the sentence - 50 years with parole at 35 for good behavior.

    The folks on 14.313, 7.200 and 3.840 would all support such a sentence I'm sure....

    Thanks. :)
    But calling on-frequency certainly is. :cool:
    I guess you could say that your radio is only accurate to 300ppm, and you'd have a great defense for using the entire channel. :eek:

    Matt and I previously discussed this at length. The rule requires one centered signal per channel at a time because NTIA wants to be able to identify the station interfering with its Primary Users.

    "On 60 meters hams are restricted to only one signal per channel and automatic operation is not permitted. In addition, the FCC continues to require that all digital transmissions be centered on the channel-center frequencies, which the Report and Order defines as being 1.5 kHz above the suppressed carrier frequency of a transceiver operated in the Upper Sideband (USB) mode."

    33. Operation on Channel Centers. Section 97.303(h) currently requires that amateur operators ensure that their station's transmission occupies only 2.8 kHz centered at each of the five center frequencies. The NPRM proposed that, for amateur stations transmitting CW emissions and PSK31 data emissions, the carrier frequency shall be set to the center frequency. NTIA has requested that we continue to restrict amateur service transmissions in this manner. *59

    34. ARRL states that it is possible to have multiple CW and/or PSK31 communications ongoing simultaneously within the 2.8 kHz channel, so long as those simultaneous communications are not limited to the channel centers. Two commenters (Hambrecht, Richmond) recommend that multiple emissions be permitted, if the emissions outside the allotted channel are suppressed.

    35. By contrast, NTIA opposes the authorization of multiple emissions within a 2.8 kHz channel and claims that such an action would significantly increase the likelihood of harmful interference to important Federal operations and that difficulty in identifying interfering amateur stations could significantly inhibit rapid use of these channels by primary Federal stations for such uses as emergency communications.63 NTIA observes that all five of the channels allocated for secondary amateur service use are also authorized for use by primary Federal stations, and states that the five channels were provided to the amateur community in order to meet requirements for disaster communications, and that use of additional frequencies would not enhance interoperability with Federal stations.

    36. We adopt the center frequency requirement as proposed in the NPRM. Because the amateur service operates in the 60 meter band on a secondary basis, we pay particular attention to NTIA’s position and the interests of Federal agencies that have primary status in the band. We conclude that continuing to restrict amateur stations to transmitting on the center frequencies will maintain the limited number of amateur operators using the five channels at any given time and provide certainty as to where such operations can be found. By not upsetting the expectations of the Federal users of the band, we are confident that they will be able to immediately reclaim these frequencies from secondary amateur radio operations, if and when necessary. Accordingly, we amend Section 97.303(h) to specify that control operators of stations transmitting phone, data, and RTTY emissions (emission designators 2K80J3E, 2K80J2D, and 60H0J2B, respectively) may set the carrier frequency 1.5 kHz below the center frequency, and that, for stations transmitting CW emissions (emission designator 150HA1A), the carrier frequency is set to the center frequency.

    *59 See Letter from Associate Administrator, Office of Spectrum Management, NTIA, to Chief, Office of Engineering
    and Technology, FCC, which was submitted on September 2, 2011 (2011 NTIA Letter).


    March 28, 2012

    In an e-mail response to ARRL Chief Executive Officer David Sumner, K1ZZ, Karl Nebbia, Associate Administrator of the NTIA Office of Spectrum Management, stated, “NTIA has no interest in limiting the types of emission used by the amateurs as long as the data emission does not exceed the 2.8 kHz bandwidth generated by the upper sideband transmitter.” Nebbia referred all further inquiries to the FCC, which “…sets the conditions for use of the five 5 MHz frequencies by the amateurs.”

    The requirement of only one signal per channel remains, as well as the prohibition against automatic operation. The FCC continues to require that all digital transmissions be centered on the channel-center frequencies, which the Report and Order defines as being 1.5 kHz above the suppressed carrier frequency of a transceiver operated in the Upper Sideband (USB) mode. This is typically the frequency shown on the frequency display.

    Because there's no hierarchy among the rules, anyone not adhering to the 60 meter rules is potentially just as culpable as the people on the freq's W7UUU just mentioned.

    It's so E-Z, even an ARRL No-Test Gen-Tech could understand it!

    Imagine if the foregoing were wrought for naught by one small paragraph:


    Concerns about "center frequency" long ago dispelled per ARRL in 2012.

    "In an e-mail response to ARRL Chief Executive Officer David Sumner, K1ZZ, Karl Nebbia, Associate Administrator of the NTIA Office of Spectrum Management, stated, “NTIA has no interest in limiting the types of emission used by the amateurs as long as the data emission does not exceed the 2.8 kHz bandwidth generated by the upper sideband transmitter.

    That's interesting.

    And -

    The requirement of only one signal per channel remains, as well as the prohibition against automatic operation. The FCC continues to require that all digital transmissions be centered on the channel-center frequencies,

    I try to operate as near the center as possible, but, observing the objective of minimizing interference to other operators on the band sometimes I have to choose the next open 50Hz slot above the one in the center.

    Does the FCC or NTIA listen by ear to our transmissions (obvious they would for voice/SSB and CW/code), including say, FT8? Or is it possible they may make use of the usual contemporary WSJT decoding software to do this?

    What is the ARRL stance on this in 2019 and with the development of FT8? Have they stated anything recently?

    I think the following says it all; the FCC and the NTIA both require one signal per channel at a time. Does that mean you'll be cited if you don't adhere to the rule? Probably not. Even if they did cite someone, the FCC hasn't won a case in court against an amateur since Baxter, and though he wasn't the sharpest knife in the drawer, he still managed to have over half of the commission's allegations thrown out. Also, he never paid the judgment, and he stayed on the air until he died; so there's that too.

    Just out of curiosity, just where has the WARC band agreement been officially codified? I read things a bit differently, unless things have (quite possibly) changed over the years.
