(Please trim inclusions from previous messages) _______________________________________________ A question...is it really limited in bandwidth to 19.6K on 2m and 56K on 440 or is it just that this is the maximum used by the modes in common use? While at Data Radio (now calamp) we had 56K on a standard 20KHz channel for Police/Fire and Utilities. Their Viper Radio claims 32kbps on a 12.5khz channel. (as you know there are no more 20khz freq for commercial)

(Please trim inclusions from previous messages) _______________________________________________ Hello all,
I don't like the idea of regulatory discussions on this list.
However, I am curious (as it's pertinent to what we do on this list) what the rules are in other counties for ham radio.. So far I haven't had much luck finding the answers on the web.
Presently in US ham radio data bandwith: 2 meters is 20 khz max, 19.6 kilobauds 70 cm is 100 khz max, 56 kilobauds
Ironically, while there is plenty of space on 70 cm, other modes like ATV are permitted to occupy up to 6 MHz of bandwidth.
Since we have a nice mix of hams from all over the world on this list, I'd appreciated a reply (can be off list) on what is permitted in your country on 2 meters and 70 cm.
Thanks,

In the Netherlands, if it fits in the bandlimits you can legaly use it
regardless of mode, band or speeds. Offcourse you have to wonder if it is smart to use a small band like 2 meter (2 MHz wide) with very wide modes.
