Andrew,
Any news when this digital mode might be out to use?

Cortland,
I would imagine the mode works well for passing MARS traffic. Contestia
seems to have about the same wpm rate in the 8 tone / 1k configuration and
throughput seems to be better. There's no latency either so it might be
worth a try.
Not much use for wide high-speed chat modes on the h

Hi Frank,
The FCC rule about HF signal bandwidth limit
related to a "phone emission of the same
modulation type", applies mainly to Image
When the FCC uses the term "of the same modulation type," that would be
the first symbol of the ITU Emission Classification system or the "main
carrier modulation." Thus, if you are using SSB as the primary
modulation then you are limited to what is considered a communications
quality signal. A

I'm a Tempe AZ HAM looking for area HAMs interested in VHF/UHF digi mode
activity. I would like to try PSK or other digi on 6m,2m 70cm. Anyone
interested in setting up a contact time, mode and freq. can email me with info.
Thanks

Excellent answers! Thank you VERY much! I've sent off an email to the FCC and
will call ARRL to see if they confirm the information provided. Which I
suspect they will. Sweet. Made me a little nervous doing 2k wide QSOs, so I
stopped until I was certain. I was eager to try wider ones and c
FCC Data Signal Bandwidth Limit Chart for HF/VHF/MF
BandData Signal Bandwidth Limit
160 meters = 200 kHz
80 meters = 100 kHz
60 meters = 0 kHz (Data Not Authorized)
40 meters = 125 kHz
30 meters = 50 kHz
20 meters = 150 kHz
17 meters = 42 kHz

I made a typo error in the previous message.
I should have said:
For example, on 20 meters, hams in USA can
legally transmit a 150kHz bandwidth data signal
(14000kHz to 14150kHz).

Yes. Under the present "content-based" rules for
hams in USA, FCC has confirmed that there isn't
really a specific bandwidth limit for most types
