Title: DGPS Logs 9 FEB 2023
Post by: ChrisSmolinski on February 09, 2023, 1041 UTC

Unless some new DGPS stations come on the air, I think this is it for DGPS for me. Especially as we're well out of solar minimum now, which means the chance for DX from the remaining European stations is pretty much nil.  It was fun while it lasted.

Once the snow is gone, I'm going to re-orient the loop to N-S and see how well Panama comes in over time. However, then I will rarely get the two remaining Canadian stations, since they're about 75 degrees from here which puts them well into the null (which is about 30 dB) of the loop.

We'll see how long I have patience for this, especially with increasing daylight and increasing storms. Europe for here is about 45 degrees, which is neither great with the loop oriented E-W nor N-S. Don't really have a place for it at 45 deg. Plus, rarely get Europe here anyway on LW or MW with my ALA-1530S+ which is on a rotator. And then it will also be thunderstorms & more daylight.

Yes, it was fun. I've still been putting these daily decodes into my PostgreSQL DB which is rather large these days. Want to do something to analyze the data and compare to solar conditions, but haven't found a source for daily historical solar conditions. That's the easy part, the confounding part will be trying to factor in thunderstorms that may be within range, plus the local QRM that comes & goes.

I've also been saving all of the decodes and have a stack of HD's that have the data. Just in case... In case of what, I have no idea.

I would not be surprised if the decoding in ADGPS could be (somehow) improved, to maybe pull a few additional stations of the the I/Q data.

That would be good... but boy that's a lot of files (1 per hour) over the past 3 or 4 years.
