FYI:

 

3500 - 3520        CW

3520 - 3535        Narrow band data

3535 - 3575        CW, Narrow band phone and image, Narrow band data
(Overseas only)

3575 - 3580        Narrow band all modes

 

3599 - 3612        Narrow band all modes

 

3662 - 3680        Narrow band all modes

3680 - 3687        CW, Narrow band phone and image

 

"Narrow band phone" means less than 3kHz bandwidth exception of AM PHONE.

 

So for the RTTY contest, JA station can transmit in 3520 - 3580, 3599 - 3612
and 3552 - 3680 exception of 3535 - 3575 limited to with non-JA QSO.  Of
course we can only use < 3600 in U.S.

hello Hide - Thank you for the information. I found this band plan dated 21
April 2020:
 
https://www.jarl.org/English/6_Band_Plan/JapaneseAmateurBandplans20200421.pd
f
 
I see that the words "... segment may be used for NB Data communication
with overseas stations" still appear on the band plan in several places.
 
Does this mean you are not to work other JA stations on these segments?

Before going into the CQ WW RTTY contest at the last weekend of this month,
I'd like to remind you of the JA RTTY sub-bands.
 
80m  3520 - 3580, 3599 - 3612 and 3662 - 3680
40m  7030 - 7200
20m  14070 - 14150
15m  21070 - 21150
10m  28070 - 28200
 
The high light of the change this year is the expansion on 80m.
We still cannot transmit on the main zone of 3580 - 3599 but 80m has been a
little bit expanded compared to past years.
 
I will try to operate on 80m more often and hope to get more contacts than
last year.
See you on all bands including 80m in the coming WW contest.
 
Thanks,
Hide JH8KYU/1
