我找到了去年六月份的一封电子邮件，当时我请教一位日本ham（ja6idj，目前在马来西亚工作，呼号9m2idj）关于日本呼号的问题：
dear jiang-san
about ja callsigh it not so easy to explain.
because i'm also not clear as well .
i know at first government provide jaxaa乣jaxzz(no club station)丒丒before i got license.
then after finish that call jaxaaa乣jaxxzz for all personal station and jaxyaa乣jaxzzz
for club station (no relation with license).and after finish ja prefix jh and jr and je ,jf.jg
ji,jj,jk.jl.jm.jn.jo.jp.jq.and 7l1aaa乣7l1xzz (yaa乣zzz for club)then 7m.,7n丒丒丒
8j prefix for special station for example 8j1rl(shiyowa base antarctic)8j1rm(mizuho base antarctic)
8j2ai(expo japan aichi ) 8j1a..8j1ham(ham festival tokyo japan)
7j prefix for foreigner but sometimes using this prefix for special station (example 7j1rl okinotorishima) 丂
also okinawa using jr6rrr乣jr6xzz (yaa乣zzz for club) and js6 .
and okinawa has 2letter station that using kr8xx but when okinawa returned from the usa
they change the prefix to jr6 .
we can't recognize who has which class license folder from the qso but government open the
information for the each station on the website .so we can find out their license detail from the website. (expire.output power. frequency so on)
we need a radio operator license to apply amateur radio station. that operator license had
first class and second class and third and fourth class (same as your country)
1.first class丒丒丒no limit power (but normally 500w乣1kw) all frequency and all mode)
2.second 丒丒丒 200w and all frequency and all mode.
3.third 丒丒丒丒丒丒sorry not clear (maybe 50w and no 14mhz and 18mhz and 24mhz??)
4.fourth 丒丒丒丒丒丒sorry not clear(maybe 25w and no cw and without 1.8mhz 14,18,24??)
me and my wife has a first class license . i want an apply 1kw output power
license to enjoy to get more country on 6m.
..........
中间那些乱码我觉得应该是破折号和空格吧
