Log4OM

I am on 2.8 and I am wondering how many call signs have I worked? I have over 10,000 digital QSOs but I am guessing I probably only have worked 2,500 call signs - the rest coming from duplicates on a band (I usually will re-work someone I have had a QSO with on a band if they contact me) and from working others multiple times on different bands.

I tried to figure out how it could be done in 2.8 but no joy.

Anybody know how I could do this?

You can do that relatively quickly with PowerShell text processing.

In Log4OM:
File->Export CSV
check ONLY the call field
save to "calls.csv"

In PowerShell:
Get-Content .\calls.csv | Sort-Object -Unique | Measure-Object

You can also get a list of your 10 most frequent contacts in PowerShell:
Get-Content .\calls.csv | Group-Object -NoElement | Sort-Object -Property Count -Descending | Select-Object -First 10

No experience with powershell.
But will try your suggestion and let you know.
Thanks,

Ran Powershell with your specs and got an unexpected answer.

Out of 10,047 contacts I estimated that probably 2,500 were unique. Mainly because it seems like most of my contacts I have worked before on other bands so I only want to count all of the multiple contacts with the same call sign as only one.

My answer was 6,644.

So I made up a test file to which I knew the answer. Ran it and the answer was correct.

So thank you on two accounts. One - I got my answer. Two you made me aware of how to use Powershell.

Thanks again and stay safe!

Congrats on all the unique calls!

Glad PowerShell answered the question. I am not a PS expert (more comfortable with awk and sed) but it's useful for quickly exploring Windows text data . PS can handle multi column data reasonably well, so if there is interest in things like "how many unique Olivia contacts on 30m in 2019?" I can probably pull together some more advanced report examples.

Stay safe.
