Designator Appended after/before Call Sign

[ General ]   [ Prefix ]   [ Suffix ]   [ Special Operation ]   [ 7J-8N ]   [ Designator ]   [ Official Criteria ]   ( )

  1. Rules
  2. Currently, in Japan, no legal rules exist on a designator after/before a call sign, while the follows are our customs.

  3. Portable and Mobile Operation — "/(Call Area)"
  4. "/(call area)" — eg. JG1VGX/3

    Some Japanese stations may use "(call sign)/(call area)" like JG1VGX/3. It's customary to append "/(call area)" based on JARL's recommendation. This may have two meanings.

    NOTE: ANY of the portable/mobile stations MUST run 50W or less output, even if the licensee has the 1st or the 2nd class. In addition, on 23cm, mobile/portable operation must be 1W or less. More limitations exist in SHF and upper.

    "/(one's own call area)" — eg. JG1VGX/1

    If someone uses "(call sign)/(one's own call area)", like JG1VGX/1, he/she is within his/her own call area but apart from his/her station address.

    Confusing fact about portable operations by 7K2-7N4 series licensees. e.g.


    Someone in a holiday in Okinawa use either


    Likewise, "/JD1" is used usualy in Ogasawara, including Minami-torishima I.
    In Japan's call sign rule, there isn't any difference between two DXCC entities, which are sometimes written as JD1/O and JD1/M — "Ogasawara Is. (including Iwo Is.)" and "Minami-torishima I." respectively.


    Some operators append "JD1/" in advance of his/her own call sign in Ogasawara.

    Examples of "JD1/"
    JD1/JA1AAApr. 17, 2007
    JD1/JA1BVADec. 31, 2006 - Jan. 1, 2007

    "/7J1" and "/7J"

    In our past, "/7J1" and "/7J" were used in "JF1IST/7J1" (1979) and "JF1IST/7J" (1997, 1998), for Okino Torishima I. But now announced like "JQ1SYQ/JD1" (2001) even there.

    KG61D1963Counted as Ogasawara Is. (Bonin and Volcano Is.)
    7J1RL1976Separated Entity
    JF1IST/7J1997Counted as Ogasawara Is.

    "/M" and "/CM"

    Mobile in a car — some may use "/M" or "/CM" (but these two are unofficial even in our old day's rule), others may use "/(call area)." Mobile on bicycle, walking with hand-held — we tend to use "/(call area)" rather than "/M."


    This indicates Maritime Mobile (official, in our old rule).


    This indicates Aeronautical Mobile (official, in our old rule).

  5. QRP Operation — "/QRP" and rarely "/QRPP"
  6. The station operating output 5W or less may add "/QRP." Furthermore, "/QRPP" means 0.5W or less.

  7. Commemoration
  8. "/SO2005"

    This is the first special designator in JA. To help commemorate "2005 Special Olympics World Winter Games Nagano Japan," pre-registered Hams are eligible to identify himself/herself by appending "/SO2005" to their call signs July 11, 2004 - Mar. 15, 2005.
    [Organizer: JARL Nagano Prefectural Branch]


    Some related amateurs to the "CQ Amateur Radio" are authorized to sign "/60," like JE1CKA/60,during the CQ Gang Award on-air party celebrating the 60th anniversary Jan. 1 - Mar. 1, 2005.
    [Organizer: CQ Amateur Radio]

    "/OKA50" etc.

    These are for the 50th anniversary of Japanese Amateurs in Okinawa. On June 22, 1961 — during the control of the United States — the first station by a Japanese in Okinawa, was on the air as KR8AB. These special designator is used in Okinawa, Jan. 1 - Dec. 31, 2011.

    Each Location

  9. Contest — Designating "in the Hosting Prefecture"
  10. Some domestic contests ask for the stations inside the hosting prefecture to append a designator.

  11. Award
  12. "/RS"

    "RS" stands for "Roadside Station (or Michi-no-eki)." We have about 800 Michinoekis all over Japan. Kuji Sunkist Club, JR7YKK issues "Michinoeki Awards" to hams who got a certain number of QSL cards, on which Michinoeki stamps put. I first heard this "/RS" designator in Sept., 2004.


    Island peditioners — especially for the following awards — sometimes append "/JI#" to emphasize that they are in their such duty.

  13. Reference
  14. "/P"

    We never use "/P" for portable operation, whether fed by batteries or generators. We use "/(call area)" too, even in a such case.


    A LID reportedly sent "/Q," in stead of "/QRP."

    "/JB" and "/JB8"

    UNOFFICIAL made-up designators were used on Torishima I. in our past:

    1. JA7QQ/JB during his stay 1961-1962
    2. JA1BRK/JB8, JA1HQG/JB8, JA1KHG/JB8 and JA1WU/JB8 at "Torishima Island '63 Summer DX'pedition."


    "JA#/(licensing country's call sign)" — eg. JA1/W1AW

    NEVER, unfortunately (I'm sorry to say this).

    He/She who wants to operate in Japan will have some ways.

    The follows are the descriptions of "how to QRV in JA," according to this tree:

    +- A. Japanese Speaker
    |  |- a. National Exam
    |  +- b. Lecture Course
    +- B. Others
       |- a. Reciprocol Agreement -- any nationality but licensed by W, DL, VE, VK, F, HL, OH, EI, OA, ZL, YB or CEPT
       +- b. Others
          |- I. Expo Visitor
          +- II. Others -- sorry, you have no chance
    1. For Japanese speakers
      If you can understand Japanese language very very well, you're eligible to get a JA operator license through either of the following ways, like native Japanese amateurs. Any nationality is acceptable.
      1. A national exam
        Held by Japan Radio Insutitute — an incorporated foundation — as follows:

        4th¥5,000Every month or every quarter, depending on the venues
        2nd¥7,450Three times per year

      2. A lecture course
        However, an end-of-course exam exists:-) And mainly only for lower classes at expensive cost. A course's contents and hours are defined by an ordinance of the Ministry of Internal Affairs and Communications (Musen Jujisha Kisoku, or Radio Operator Regulation) as follows:

        ClassRequired Course Length (hour(s))Remarks
        Radio Engineering
        End-of-course Exam
        4th461Typically two full days course in weekends
        3rd6101Typically one full day 2+4 hours shorten course, for 4th class licensees' upgrade
        2nd35272.5Typically ten full day 29+17 hours shorten course, or alternatively, an "eLearning" course, both for 3rd class licensees' upgrade

        Seven organizations provide such courses so far. Since 2009, the ministry permits for nongovernmental enterprises to hold them.

        In addition, graduates from the following three "Long Term Lecture Course Cirtified School (or Choki Gata Yosei Katei Nintei Ko)" can automatically get a radio operator license — which includes 4th Class Amateur Radio Operator's privilege — in conjunction with their guraduation.

    2. Otherwise —
      1. Reciprocol Agreements
        If you have a license of the eleve countries in the following table — but, nationality is ANY —, the reciprocol licensing agreement is available, according to Ministry of Posts and Telecommunications' Appended Table 1, Public Notice #326 of June 16, 1993.

        Additional privilage in a club station
        Especially, if you have a license of the following four countires, you may get some additional privilege in a club station, according to Ministry of Posts and Telecommunications' Appended Table 2, Public Notice #326 of June 16, 1993, under the control of a JA's 1st or 2nd class licensee.

        e.g. If you're an American Advanced class licensee, you will be restricted up to 200W output regardless of your 1.5kW skills in the home country, under the basic reciprocol agreement which considers you as a Japanese 2nd class licensee equivalent.
        However under the control of a JA's 1st class licensee in a 1kW — the Japanese legal limit — club station, you can QRO up to 1kW.
        (But in this example, some restrictions still remain: only in the US Advanced class sub-bands even inside Japan.)

        Anyway, if you want to become a member of a club station, without your own individual station licence in Japan yet, you have to get an "eligibility certificate" from the Bureau of the Ministry in advance, using a form of "Appended Table 3" in the public nortice, regardless of the execution/unexecution of the additional rights above.
