[RTTY] Bandwidth Limit ...

[Joe Subich, W4TV]

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.

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?
