ARRL is *wrong* ... there *is* a limit for data bandwidth on the HF
bands. It is found in 97.3(c)(2) which defines data -
(2) Data. Telemetry, telecommand and computer communications
emissions having (i) designators with A, C, D, F, G, H, J or R as
the first symbol, 1 as the second symbol, and D as the third symbol;
(ii) emission J2D; and (iii) emissions A1C, F1C, F2C, J2C, and J3C
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.
[54 FR 25857, June 20, 1989]
Emphasis added ... note the very definition of DATA limits bandwidth
to *500 Hz or less* on all amateur frequencies below 30 MHz.
Now who wants to argue that ARRL should be allowed to change the
rules *or* that Winlink should be permitted to continue using
*ILLEGAL* transmissions?
