	Digital Club files (upgrade in progress)
	for N1MM, N1MM Logger+ (Call History) & Logger32 (CheckCall)*

* Data may be usable in other logging programs
Notes: This data is for clubs dedicated to digital modes or where the vast majority of members use digital modes.
Clubs with FT8 in their name are weird, as 'data' cannot be exchanged because of the very format and they'll be outdated, fast.
In RTTY contests, please don't exchange names, unless required. RTTY contesting is tough enough, without wasted time.
This page does not and will not provide any member related information except for: Callsign, Christian Name, Surname†, SPC†, Number, Club.
*** Source data is entirely in the public domain, which can be proven by using the 'Reference Link' entries (by club) in the table below. ***
† Only if supplied by club (SPC is location; State, Province or Country)

>>>>> 62599 Digital club memberships* <<<<< Jump to files Version: 2021-10-23.1
N1MM Logger+ ~[memberships + no. of clubs]	60649	2021-10-19
Logger32 CheckCall shows all lines, including comments (#) and header strings (!!)	59388	2021-10-23
Super Check Partial (.dta) includes all callsigns across all clubs	59388	2021-10-23
Super Check Partial (.dtb) includes all callsigns across all clubs (Win-Test format)	59388	2021-10-23

* This is a correct total. Your logger may report a slightly different number.
The data amounts to most of the digital club members in the world.
This page has been active since 2019-12-14, with an initial 6 clubs.

***How to display real-time lightning map while running logging programs***

Additional commands available in the callsign field:

LATEST	date and time, most recent update
RECORDS	number of records in file
CLUBS	number of clubs in file
FILE	filename/path (truncated) of file

Club Call History files work with Logger32 when add-on CheckCall (by JA1NLX) is used [tested with v7.0.1.0 and earlier]
CheckCall shows ALL club membership numbers, etc., unlike CallHistory checking in N1MM Logger+

Earlier versions had a different appearance (single window)

digital_clubs_call_history.txt shows all club memberships listed here against each callsign entered in N1MM Logger Classic and N1MM Logger+
Files have been tested with N1MM Logger[+] in DX mode only

Membership no. shown is the last club found e.g. RDRC

Any single Call History file can be loaded for one club (e.g. soc_call_history.txt)

Upcoming/Current/Recent DXpeditions using N1MM Logger+ as their logging program

ZK3A, A35JT, VP8PJ, 3Y0J, C6AGU, FO/AA7JV, VP6A, CY9C, KH8T

N1MM specific:
As Office/Access Jet engine is used (not SQLite), loading of large Call History files can be very slow!
N1MM Logger+ specific:
N1MM+: You can load any of the Call History files using File/File Import/Import Call History.
Select digital_clubs_call_history.txt if you want all of them as one file.
Make sure that the entry window is wide enough to display high membership numbers. They are not displayed truncated, they completely disappear!
Try using a club with many members, where the numbers can be 5 digits long.
You can show member spots only in the bandmap by going to Telnet/Filters and enabling 'Show only spots that are in Call History'.

Use with other logging programs

CQRLOG [Linux] uses 'stripped down' versions of membership fields. You'll need to 'translate' the files to make them work^1,2
Examples: Call or Call;Number or Call;Number;Date Start;Date End [where dates are in format YYYY-MM]

DXLog uses a different syntax for "CallHistory" files {not documented in web page or Wiki}. You'll need to 'translate' the files to make them work¹
Examples: Call=Number or Call=Name;Number

drlog (N7DR) [Linux] uses the 'raw' files successfully.

1) As there is no 'User Text' field to denote a club name, combined listings cannot be meaningfully used with this program
2) As there is no 'Name' field, this reduces useful data from most clubs

It seems pretty obvious, that with N1MM Logger+ and Logger32 dominating their respective logging slots (contest/everyday), it's about time that other programs made more use of Call History files and that they and the existing ones use more options. Confused? Go here for more.

Original clubs: 070, 30MDG, CDG, DMC, EPC and FELDHELL [December 2019]
New clubs: NDG and RDRC [December 2019] BDM, EUFT8C, FT8DMC and HPC [January 2020]
RTTYcom [October 2021]
1. After loading Call History file, N1MM may turn off lookup. Don't forget to turn it back on.
6. Server #fsize function returns 'K' incorrectly, when it should be 'k'. Blame lack of SSI standards for this.
7. There may have been no changes since last check. Based on last update of {xxx}_call_history.txt files, granular to the second. We try to update at a better rate than 50 days.
8. Data not complete (currently). Typically, '[an error occurred while processing this directive]' error will be shown.
Data is not included in the main digital_clubs_call_history.txt or digital_clubs.txt files. Data (untested) may be available in the raw and call history files for this club.
9. All of the non-comment lines in the file. This is not the number of all-time members. Some membership numbers have multiple callsigns. SKs lines are commented out.
11. Latest membership number. 'none' indicates club doesn't issue membership numbers.
12. Latest update overall. Filename changed to digital_clubs_call_history.txt

You can jump to the end of 'Reference Link' pages by using 'End' and jump to the top by using 'Home'.

Most of these clubs have free membership, except for those noted. Fastest growing clubs are ??????.
