Juan,
Am I wrong to assume that skimmers are not calibrated? They should be
calibrated to S-9=50 uV into 50 ohms at least to
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

Some long-time observations from about 55 years of AM broadcast band

It is tricky to use receiving tests to gauge the

One excellent example of use vertical array for HF on the beach was VP6DX

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
Hi Guys,
ENOUGH of the ...modeling the proverbial 'vertical on the beach' already...!
My delete button is beginning to wear out.
Just ...Build it, and they will come. Period.

I swear I am going to start a self serving thread called “ vertical near by to
a beach.”☺

If you believe - no proof is necessary. If you don't believe - no proof is
possible! J
