Thank you for the reference Paul. Regarding the quote by N4ZR stating: I had earlier understood that SNR was calculated in a relatively short interval just before the spot was sent to the Telnet server. Turns out that the calculation is based on data collected in the 50-Hz decoder channel for

I don't believe it waits 45 seconds before reporting, Skimmer is posting spots within a few seconds of starting. I think the reference was to an assessment of band noise up to and including the previous 45 seconds used in computation. With QS1R here the measured and reported snr compares

I know what I am going to say isn't talking about 160m, but pertains to a vertical on the beach. Quantifying, with anything but anecdotal data, the difference between a horizontal antenna located inland versus a vertical on the beach would take something more than a short experiment but here

As I recall, ZF1EJ's station uses a log periodic, a tribander and possibly other antennas and he is on the southern side of the island. Log periodic antennas typically do not have much gain if they were using that. While there is no proof that I am aware of, stations new the sea facing their

Years ago when I was working the 80 meter DX from the mobile, beyond working VK6LK long path, I was checking out salt water locations. I found that the closer I got to the East facing salt water, the stronger Europe-Africa received signals. Getting right up to the water edge was noticeable

That was a very interesting post Mark and thanks for taking the time. In the mid 60's to 80's I was very interested in LF and MF BCB DXing and at first I had a loaner HRO-500 (I worked at National 1963-69) and later my own with the LF-10 preselector which I still have and use here for general
