OK, Mark, then it does look like we are not going to be able to use the wider modes in the CW/RTTY/Data area. I am not sure what wide modes you are referring to that are not sent with J2D as all of the ones I can think of are done with injecting tones into an SSB transmitter.
I did find the reference: - - - - - - ยง 97.3 Definitions. (c) (2) Data. Telemetry, telecommand and computer communications emissions having designators with A, C, D, F, G, H, J or R as the first symbol; 1 as the second symbol; D as the third symbol, and emissions A1C, F1C, F2C, J2C, J3C, and J2D having an occupied bandwidth of 500 Hz or less when transmitted on an amateur service frequency below 30 MHz. Only a digital code of a type specifically authorized in this part may be transmitted. - - - - - - - Therefore, it does not appear to be an error when you consider their earlier discussion of having narrower band modes in the data area. I keep forgetting that we still have the RM-11306 bandwidth proposal coming eventually. However, I am beginning to suspect that the FCC has "telegraphed" some of its thinking along those lines. Maybe they will reverse themselves or maybe they will do the right thing and keep all data/CW/RTTY areas at or below 500 Hz and allow wide band modes to operate in the "phone" section. Then there would be no reason at all to even further address a complicated 200/500/3500 Hz scheme. It does appear that Pactor 3 and wider modes as I mentioned earlier (Olivia, MT-63, etc.) may not be possible when this is finalized. Also, they would have to revist fully automatic control segments and either prohibit or allow automatic operation in some segments, either in the CW/Data or Phone areas. I guess we now have to wait and see if ARRL finds out any additional new findings or clarifications. 73, Rick, KV9U Mark Miller wrote: > Rick, > > The text in the R&O indicates that the 500Hz maximum occupied > bandwidth only applies to the new emissions designators added to the > definition of data. and the affected bands are below 30 MHz.
