Hi Lee, glad you have things working now. As you've found the two S@N files contain conditional action script allowing detection almost out of the box. There are other conditional action scripts out there depending on what you want to do. I found that after a while detecting the first meteor trails and checking everything worked that I wanted to reduce the number of screenshots taken (to preserve some hard drive space mostly). More recently with 'The Admiral' I have been looking at the initial parts of a number of signals showing increasing and decreasing frequency, but that's deeper down the rabbit hole. Others are keen to record both the screenshots and audio. Some wish to send off their data to the Radio Meteor Observatory (RMOB). A lot of the learning is trial and error and I would say have fun experimenting, making mistakes but learning all the time and reading up as much as you want as meteors are a fascinating area of astronomy. You will produce your own data and compare with others and do this 24/7 regardless of the weather and in the comfort of your own living room. No more only being able to observe one night in five anymore and light pollution doesn't matter.
Initially Spectrum Labs can come over as very detailed (which it is) and this can be daunting but later it turns into a very flexible tool that you can use to explore detecting meteors with. The manual that comes with the software is a good start. I don't think you ever stop learning and I have come to regard meteor work as the most rewarding part of astronomy I have done, it's certainly the most cost effective by far :-)

There's also a lot of SGL threads which you might find interesting too Lee, we are all learning together. Let us know how you get on.
Best of luck,
