N1MM Logger

If you are using the N1MM contest journal, you can use konfiguračný UDC (User Defined contest) súbor.

Notes:

1. The UDC file is saved in the directory UserDefinedContests
   (beware - N1MM+ in Windows 7 and higher can create two directories with this name).
2. The received power in the generated Cabrillo file will have 3 characters, not 2.
   The N1MM(+) program does not calculate with so many parameters, there was no other option.
   This data can be easily corrected in the resulting file with an editor.

It is possible to change the default information about the custom upload code in the file
(10 BPV/006 – input district/membership number) in the line:

DefaultContestExchange=10 BPV/006 

or enter this information when opening the diary for the first time.

Accessories

In case of equality of points, the number of connections established in the first thirty minutes is decisive.
Unless otherwise stated, the General Terms and Conditions of Short Wave Races and Competitions apply.

Evaluation

The results will be published at the QRP meeting in Chrudim in March.
They will also be published in the OK QRP INFO bulletin, in amateur radio magazines,
in the broadcasting of radio amateur organizations and on the website of the OK QRP club.

Explanation of some terms

Any device can be used in category A, as long as the participant ensures compliance with the input (power) limit.
In category B, the obligation to use chemical resources also applies to this condition.
