THE ARRL COMMENTS ON RM-8926 THAT'S NOTEWORTHLY
Frederick Maia in 1995 sent a purposal to the the FCC (RM-8926) to put information bulletins above 30 MHz. This is a footnote from the ARRL comment, and worth a read "Maia criticizes the inherent infeasibility of information bulletin and regular scheduled code practice from W1AW to "listen before transmitting". The League believes the regularly published, widely disseminated schedule of the W1AW bulletins and code practice, the limited duration of each, and the advance warning transmissions are sufficient to address that concern. However, it should also be noted that such a capability, even if feasible, is not particularly practical, given the dynamic propagation characteristics in the amateur MF and HF bands. For W1AW operator (or any amateur radio operator) to listen in New England before transmitting is not a guarantee against interference to other amateur stations. If W1AW is in the skip zone of a station transmitting, W1AW will not hear the transmitted signal. That does not mean, however, that the intended receiving station is in the skip zone of W1AW. Nor are electronic circuits to determine frequency activity successful at HF. One reason is the noise level varies constantly by both types and amplitude. It is difficult, therefore, to discern signal from noise in these bands by use of a squelch circuit. The problem is further complicated by the fact that HF frequencies are not channelized, and receiver bandwidths vary from amateur station to amateur station. These matters, however, are no more a problem for one-way information bulletins from W1AW then they are for any amateur station engaged in two-way communication, and do not offer any support for the allegation that HF bulletins, voice, cw, or data, are somehow improper on the HF bands."
