Hi,
Yes I did play around with capture count... I selected a number, then
ran the program for a few hours, and looked to see how much of the
screen was filled. I then used that data to infer the right number to
use to get a 24 hour capture that just filled my empty frame.
Someplace I found a method to calculate the correct number, but it only
worked on one machine. If I applied the same procedure o a different
machine it would fail...
So I just punted and used the method outlined above. I seem to remember
getting a capture every 15 or 20 seconds to fill the screen... It all
depends on the resolution you are using.
I have a set of numbers I use, that fill the screen in 24 hours, 12
hours, and 4 hours... I use different time resolutions to help pin down
start times, or to view the RFI in a different time window...
73s and thanks,

Thanks Dave....attempting to setup a RSP1A for the screenshots as you
described.....1920 seconds, every 32 minutes? Is that enough to capture?
Did you try any other time frames?

See my article in the March issue of CQ magazine, or visit:

If it were me, I would be documenting my current RFI environment,
using the technique described in both articles... That way, you know
and can document what you have now... PRIOR to turn on!
Start a log of every person you talk to, by name, include date and
time, in addition to what was discussed.
Be friendly, nice, but take notes on everything you say, what was said
to you, and what you do.
Read up on Part 15... Approach is everything, be nice, don't
threaten, don't cause a stink, always leave yourself in a position you
can defend...
I would also contact the ARRL Labs for some advice as well, prior to
talking to anyone... Paul replaced Mike Gruber there, and he seems to
be a good fellow to know in these sorts of situations. But do start
your documentation process today!

Never thought I'd see it here in perpetually cloudy NW PA, but the
neighbor across the street is getting some sort of roof mounted solar
array installed.....I tried striking up a friendly conversation with
the installers about what kind of system it was, but when they heard
"ham radio" and "interference", that was the end of the
conversation....the one guy said they never had a problem with radio
interference before, but when I asked if they ever installed one next
to an amateur radio operator, he couldn't say.....soooooo......what
should I expect? Hopefully, there will be no issues, but if there is
?!?!?!?!?
