Long time LOG4OM user and major advocate trying to educate all of my friends in Northern California. I have a question which is probably a FAQ but have searched every combination of words to see if this subject exists with no luck.
I have a multi-multi type contest station with multiple monoband yagis and other antennas and 3 operating positions on a 7 meter bench that me and some mates operate contests from. For contests we use N1MM in a multi configuration mode running on 3 or 4 different computers. N1MM has an elegant networking feature which allows each station to operate independently on different bands while sharing all data on the network.
I have been using a fully integrated FT8 station with an Elecraft K3 using LOG4OM and WSJT-X , JTAlert and the Virtual Port emulator . It works flawlessly and with a single entry key to complete the QSO and make the log entry. I keep my log file on dropbox so like others I can run multiple locations and field operations using the single dropbox log file. Everything is perfect.
I recently set up a second and now third station so I can run multiple FT8 stations at the same time. I know, I am also writing a book called " Beyond Type A" ..
The question is, can I have multiple copies of LOG4OM running on multiple computers all sharing the same log file over the internet on dropbox ?
I am also experimenting with the idea of just importing and ADIF file from time to time from the 2nd and 3rd station. I seem to remember seeing something like that mentioned previously. If that is the only suggestion can that be done on some kind of Chron job that would initiate the ADIF import from time to time.
Thanks again for the great system and your outstanding support
regards

Re: Multiple Computer Support
Yes you can and that is exactly what I do.The question is, can I have multiple copies of LOG4OM running on multiple computers all sharing the same log file over the internet on dropbox ?
However if it is possible that more than one station might write to the log at exactly the same time then you need to change to a MySQL database which will allow this.
There is no need to do this if you use either a common SQLite or MySQL databaseI am also experimenting with the idea of just importing and ADIF file from time to time from the 2nd and 3rd station.

Thanks for that information. Yes the multiple writes does work but I a will be unable to prevent simultaneous writes with my current design so I will switch to a MySQL DB when I get a chance..
Thanks very much

Re: Multiple Computer Support
OK, almost 2 years later I am asking the same question. So if I understand;
1- Log4OM does not create an ADI file that my Main/Master can point to for updated qsos unless it is done manually and imported? This is cumbersome. I manually do it that way for N1MM+ contest qsos.
2-I can convert my sqlite db to MySQL and have both computers share the same MySQL DB which can be located on the Main/Master computer?
Thanks if true we may be on to something here.

Generally Version 1 is only interested in import of ADIF's or QSO's and does not broadcast the data, V2 may do this but of course there is a backup ADIF automatically generated which could possibly be used, if this is set in the V1 options?
Integration with N1MM was added some time ago so now N1MM automatically adds QSO's to Log4OM as they are logged in N1MM.
Yes you can and this is what I suggested if Sinultaneous logging is required in my last post2-I can convert my sqlite db to MySQL and have both computers share the same MySQL DB which can be located on the Main/Master computer?
