Here are my reception reports from last night in Belgium
Reveiver: Elad FDM-S2
Antenna: Giant EWE to Northwest in semi-rural area
Note that there are some stations only decoded very few times. However I hardly have any possibility to veryfy the spots. On the other hand, I heard NDB "LT" on 305kHz very loud (15-20db signal to noise ratio) - so it is clear, that stations from 5000km away or more can be very loud here, if propagation is well...
I have no idea, if central and south America may be valid decodes... probably not... so please be careful!
Canadian stations were very loud here - VOCM on 590kHz was S9+20db sometimes last night!
Regards from Belgium!

Note that there are some stations only decoded very few times. However I hardly have any possibility to veryfy the spots. On the other hand, I heard NDB "LT" on 305kHz very loud (15-20db signal to noise ratio) - so it is clear, that stations from 5000km away or more can be very loud here, if propagation is well...
I have no idea, if central and south America may be valid decodes... probably not... so please be careful!
It can be difficult to determine which decodes are real and which are not. Some of them are certainly not, such as those from stations no longer on the air, like Rock Island IL.
One technique I like to use is to examine the exact decode times for the stations with only a few decodes. Double click on that station in the main window of Amalgamated DGPS, and you will get another window, showing the decode times. If there are several that are closely spaced, say with a few seconds of each other, then it is more likely that they are valid, due to a brief opening.
Also make sure the max Zcount error setting in the preferences is a reasonable value, say 10 or so. I also tend to set the minimum counts to display to 2, not 1, assuming any station with just one decode is highly questionable, but that is a personal preference.
Your catches of US and Canadian stations with dozens, as well as hundreds or thousands of decodes are almost certainly valid. Lots of decodes in the 5,000 and 6,000 km range - impressive! This is with your EWE antenna?
I'd be curious to see the times for those 3 decodes from Miraflores, Panama. My guess is they are corrupted decodes from Gilze Rijen, which is very close to your QTH.
-
That's a pretty good list of stations. Will be very interesting to see the list of stations you get and compare it to what we get.
-
Many thanks for some more tricks with your great software, Chris...
I have not checked too much with the times of decoding - it takes some time...
Fortunately I can replay the recordings in my SDR and listen (perhaps try to decode just a single audio channel in a small CW-filter with some other software)
I just deleted from the list stations which are obviously false decodes, such as some Asian stations
My max Zvalue is set to 6 (as advised in your help file)...
Also PC is connected to time-server over the internet
When checking the Audiofiles I found really lots of North-American NDB signals - amazing !!
LT 305kHz, from Alert Bay, 800km from North pole is 15-20db over the noise the whole night !
YEK from Arviat, Nunavut, Canada can be heard as well....
So, even extremly weak stations can be heard from North-America...
Let me check the recordings and try to sort out false stations...
Panama and Brazil is for sure suspicious to me...

Chris,
you asked: "This is with your EWE antenna?"
Yes - picture of antenna is attached... The experimental giant EWE is much better than my 170m Beverage in same direction...
Beverages are used usually at nighttime at my web-radio you can connect through the Internet.
The Beverage antennas are better for frequencies ABOVE 1Mhz to 7Mhz... The very large EWE does not function as a real EWE above 1Mhz, because it is simply too large. So it is a real specialist antenna for NDB and DPGS. With higher frequencies the giant EWE looses directivity and noise increases heavily...
Instead at 1Mhz and above the Beverage become really long wires, as frequency increases and become more and more directive. Therefore noise on Beverages DECREASES with higher frequencies....

You are correct - on this frequency I cannot hear anything else than the strong dutch beacon - so Panama is certainly a false decode... sorry !
This evening very noisy condition with currently heavy thunderstorms north of Tunesia... lots of noise!
