3. Categories (only one can be selected)

Abbreviation = category

AB = SINGLE-OP ALL-BAND HIGH-POWER
28 = SINGLE-OP 28MHz SINGLE-BAND HIGH-POWER
21 = SINGLE-OP 21MHz SINGLE-BAND HIGH-POWER
14 = SINGLE-OP 14MHz SINGLE-BAND HIGH-POWER
7 = SINGLE-OP 7MHz SINGLE-BAND HIGH-POWER
3.5 = SINGLE-OP 3.5MHz SINGLE-BAND HIGH-POWER
1.8 = SINGLE-OP 1.8MHz SINGLE-BAND HIGH-POWER

3-2.contestov(*3)

ABL = SINGLE-OP ALL-BAND LOW-POWER
28L = SINGLE-OP 28MHz SINGLE-BAND LOW-POWER
21L = SINGLE-OP 21MHz SINGLE-BAND LOW-POWER
14L = SINGLE-OP 14MHz SINGLE-BAND LOW-POWER
7L = SINGLE-OP 7MHz SINGLE-BAND LOW-POWER
3.5L = SINGLE-OP 3.5MHz SINGLE-BAND LOW-POWER
1.8L = SINGLE-OP 1.8MHz SINGLE-BAND LOW-POWER

3-3.Multi Operator (*4)

M1 = MULTI-OP SINGLE-TX ALL-BAND
M2 = MULTI-OP TWO-TX ALL-BAND

3-4.Maritime Mobile(*5)

MM = MARITIME-MOBILE

It is allowed to use in all categories DX cluster. However, self-spotting in any form is prohibited. Stations of multiple operators can change the band after 10 minutes from the start of work on the current band, with the exception of obtaining a multiplier.

 

4. Competition code

AND : RS(T) + prefecture number (01 do 50)
Other stations: RS(T) + CQ zone number

5. Scoring

1.8MHz…………….. 4 body
3.5/3.8MHz ………… 2 body
7MHz, 14MHz and 21MHz.. 1 that
28MHz……………… 2 body
It is possible to establish one valid connection with one station on each band. Cross mode connections, cross band or via converters are prohibited.

6. Multipliers (DX stanice)

The sum of the number of different Japanese prefectures plus Ogasawara Island, Minami-Torishima and Okino-Torishima, which were worked on in each band. The maximum number of multipliers on each band is 50.

 

7. The resulting score

The resulting score is the product of the points for the connections multiplied by the sum of the multipliers achieved, e.g.. 100 points times 59 of multipliers = 5900 points.

8. Diaries

** Only one journal is accepted for the result regardless of the call sign used.

E-mail sending of log

** We strongly recommend sending LOG in CABRILLO format **
1. ASCII/Plain Text characters must be used.
2. All sent and received connections should be recorded in the log.
**Don't forget to record your zone/preferred area in the LOG as well, not even in SUMÁR**.

5. Electronic diary:

Follow the instructions in the ELECTRONIC LOGO. You can send the diary by e-mail. EMAIL LOG: Send the log file as an email attachment. Instructions [jidxelog-e.html] can be found here.
