I want to take part in my first contest - Phone sweepstakes this weekend.
I see that my log must be sent in in Cabrillo format.
My Logger 32 will not produce Cabrillo but will produce ADIF.
I see various converters out there for this purpose.
What is the best converter to use to end up with a file that ARRL will like.
Thanks, Wes AI4FH

Hello Wes,

I have seen quite a few ADIF - to - Cabrillo converters. I have never used one, so I am unable to provide a specific recommendation. I can tell you, however, that most generate a file that takes some work to be accepted by the contest log robot. They never seem to come out perfect. I very highly recommend using a contest logging program just for contesting, for these reasons:

1) A contest logging program will generate a Cabrillo file, and it will likely be correct the first time, provided you've set the program up properly.

2) Most contest logging programs will also generate an ADIF file, which you can then import into Logger32 for awards tracking.

3) Contest logging programs are better for contest use. Much like a race car, it might not be comfortable for daily use, but you'll find that it performs much better "on the track."

Luckily, you have some time before this weekend to investigate a contest logger, if you were so inclined. The software that comes to mind is N1MM Logger (, TR log by N6TR (, CT ( - out of development, but simple to use). There are many, many others. While I am not affiliated with any of them, I use N1MM at home - and it's free to download and use.

If you do decide to use your current software and a converter, I recommend taking a look at the Cabrillo specifications ( to be sure that the file you generate will be acceptable; as I mentioned earlier, files generated by these converters are usually problematic.

Good luck, and I hope to work you this weekend!

So, I have to say this whole process seems like a pain. Though, I'm sure there is a good reason why the default format seems to be ADIF for logging programs, and contests require the Cabrillo format, it is certainly problematic.

I've worked in IT for 15 years now, and I'm struggling to figure this out, by doing my own research on the internet. I don't have anyone who regularly contests, available to show me the ropes. I've tried and now the ARRL's LoTW, and can't seem to figure out how to get my logs into cabrillo format, so that I can submit my measly 20 contacts from the contest last weekend. I have ADIF files from LoTW, and have tried a number of converters which have all failed thus far. I did have one that converted the file, but would only do 10 total contacts for free.

So my question would be, can LoTW (tQSL) create cabrillo files? If so, what am I missing? I tried looking through the help, and going through the various menus. The closest I came to, was when saving, it said I could upload to LoTW in either ADIF of cabrillo, but never gave me an option for cabrillo. And when saving locally on the computer, I had the same results. It's like it will only do ADIF.

I'm sure that I'm doing something wrong, and it's probably quite simple to create a cabrillo file, I have to imagine it would have to be. But, I do have to say, that I've done IT support in various aspects (Help Desk, Desktop Services, In-shop tech, etc..) and typically I'm the one figuring out a program, so that I can teach a client how to use it and I like to think I'm pretty good at that. That said, this has to be one of the more difficult things I've dealt with, and trying to find information has been poor at best. I can't imagine being a retired gentleman, with little PC experience, trying to figure this all out on their own.

Based on what Mike said up there, I'm going to check out N1MM in the mean time. And I guess if that works, cool... but this'll be the 3rd time I'm working a log for the same contacts =(

Well I used N1MM and converted my adif to Cabrillo. I've tried submitting it, but apparently it has a number of errors in it, per the email response back from the robot. Ugh.
