This is some very neat data, Randy. Also, having Mike as your “comparison” antenna adds validity to your results because you are very close and geographical differences won’t be a factor, just some simple spacial difference that won’t impact the results.

Subject: [ADXA] Pennant PSKreporter data made easier
I can't say enough about how much Mike KB5WBH has contributed to my folly by being my reference station on 160 meters day after day.
My data collection and analysis have been much less than accurate, and I thought that someway there must be a better way to determine if the pennant rx antenna for 160 is working or not.
Knowledge is not my strong suit , but even though I may be some dumb, I ain't plumb dumb and I did make a helpful discovery this morning while comparing the pskreporter results from last night.
Chapter 2 of the pennant saga...The Discovery
Pskreporter allows a 24 hour download of your received date, so I downloaded both, Mike's from his inverted L, and mine from the pennant.
Wtih a quick Google search, I found some FREE!!! software called ADIF master that would convert the adif into a spread sheet format, with organizable columns.
I then merged the KB5WBH log, and the W5ZJ log and organized by beam heading/direction. With the pennant facing the northeast, It was easy to compare the SNR's between the
two stations. Now, no longer do I get to see the graphical pskreporter information, I now have hard data that I can see in easily organizable spreadsheet form.
Also important in comparing the two stations is the time the report was logged. As you will see in the screen shot, some times of the reports do not match between the stations.
When you see this, the data must be discarded because this is not a valid comparison between the 2 station. Only data with a similar time stamp can be compared between the two stations.
It will be easy to go in and delete the lines where there is no time match between the merged logs. This will leave some fairly decent comparison data.
Take a look at this screenshot with the pskreporter data from the two station merged. This is as much as I could get in a screen shot. You can definitely see the front to back, front to
side differences and the differnce in the favored direction of the pennant vs the inverted L.
There is much more that I would like to do, and hopefully before too long be able to compare with another low noise RX antenna at my QTH. At the present time, I have decided to seek out donations
to help me with my efforts, I am in search of additional acreage that I could attach to the back and sides of our property, and also donations of time to add to the 24 hour day so more could be accomplished
If anyone has any of thiese 2 itmes spare, I would welcome them open arms.
I am going to attach a screen shot of the log data, and also attach the complete merged ADI file if anyone should want to load it into their adif reader. If you need an adif reader, ADIFmaster is a free down load.
Have a wonderful day and good DXing
