DGPS / Re: DGPS Logs 4-5 Feb 2018

Hi Chris,
hello to the Forum,
I'm newly registered, a member from Belgium...
Nice list of DGPS - I just started to use your great DGPS-decoder program, Chris... actually starting the recording here in late afternoon...
Last night I heard a couple of north-American Beacons from East Canada and also the north east states of USA...
My best antenna is a giant EWE - I just scaled up the usual inverted-U shape for low frequency - now 20m vertical up - 60m horizontal and 20m vertical down to ground resistor of 600Ohm. Direction of max sensitivity of this antenna is towards the feedpoint (opposite of swamping resistor) - in my case to north west. This antenna is about 1S-unit better in Signal to noise than my 170meter long Beverage antenna over the fields to the same direction. It is very easy to build up such giant EWE, if you have some trees - you can also simply throw a wire over several higher trees, so you have a larger version, than the usual well known EWE... it will just work better on lower frequencies..
For East I have another Beverage of 170m ...
Also I use a long time LZ1AQ loops. Since this winter, I use 2x 1.6m diameter of 20mm alu-tubes loops side by side, but horizontal in the small tower - about 11m high. This is great antenna from 3-50Mhz. On high frequencies, such as 16m BC-band, it has considerable GAIN (about 8dbd!) due to ground reflection... on such frequencies it has also very low radiation angle...
You can connect to my web-radio (adres below) . During daylight I use the horizontal loops - during nighttime the Beverages...
Will post some DGPS recording results tomorrow (coming night)...
