Re: Sat tracking basics ?
In situations like this the best solution, if you really want a solution rather than an argument. is to supply more information.

Re: Mystery Signal on 20-Meters
Ingolf,
With the uptick in solar activity, the SW BC stations on the upper bands can now be heard. I heard WRMI out of Florida (due south of me at 1200miles) booming in on 21,525 kHz, beaming

Hi.
These signals seems to have invaded all bands. The attached screenshot includes a variety of funny signals.
I have also come across BC-stations on the higher SW BC-bands that look like

Re: Mystery Signal on 20-Meters
So much for working the UK on the upper portion of 17M!
Looks a little different today, not the rounded hump:
Just as strong on Simon's server too!
Just stopped at 1255z though, now active on 14757

Re: RSP DUO
Whilst Console does not support the diversity function I did manage to power my Duo up on it because you can select to use it as either V2 or V3. When Searching for radios just select The SDR Play

Re: software for sdr receiver
Hi Scott
As the others here have recommended, start by assuming it is an RTL-SDR. This is a common chipset used in many of these receivers.
So the place to start would be here (general guide):

Re: Mystery Signal on 20-Meters
Just another example of why its stupid to trade stocks actively (day trade).
When 70% of trades are done by algorithms you are roadkill immediately.

Re: Mystery Signal on 20-Meters
Hi all,
That's one of the High Frequency Trader signals that you see above 20 meters. These are low-latency, fixed simplex circuits providing commodities traders with a faster-than-cable-or-satellite

Re: Mystery Signal on 20-Meters
Perhaps these are related to the HF "stock-trading" stations ? They are on the same freqs as I have seen them in the past...right below 40 meters. I definitely saw them yesterday. Didn't check on

Re: Mystery Signal on 20-Meters
The signal the OP is referring to as well as the one I posted are 30kHz wide! Not the narrow signals you see down in the VLF range. The overall band scope image of these looks like a rounded mountain,

Re: Mystery Signal on 20-Meters
Not sure what is being asked, but the VLF spectrum shows well known "JXN" Norway on 16.4, Russian 'RDL' (various transmit sites) on 18.1, UK naval on 19.575, ICV Sardina on 20.27, French navy on 20.9,

Allan,
Well they are nor real, but you know that already.
My HF+ and.. a discone.
Any other antenna and it starts to look a bit like yours.. Lots of rubbish in and near the shack.

Re: Mystery Signal on 20-Meters
Thanks for the information Marco.
Maybe you can verify the signals on theattached picture (not 20m but nearer 20KHz)?
I think one is JXN on 16.4KHz, but theothers are possibly solar panel radiation
