Great work Finn! with pulses like that, you might get a regular counter to run it and accumulate for 20 minutes and take the average. My ten minute averages of 5-8 cpm using a tube with about 2-3X your volume sounds about correct. Many really good frequency counters have a count mode on their range knob.
I have several HP 10-50mhz counters purchased over the years. All have a count mode and a pushbutton for start and stop. (reset) I would hate to have to count scope pulses over that period. I have counted as low as 3 cpm and as high as 12 cpm over single minute intervals. The average always comes in between 5-8 cpm. During a significant solar CME, I have seen the local count double, and during the most massive of CME's, triple! That big one brought the aurora as far south as Richmond.............36 degrees latitude.
