Re: Frequency Scanner Plugin config

What I'd like to do is use this to scan a few known frequencies instead of scanning the entire range -- that has a lot of noise, and pick up the ones that are transmitting, i.e. for a police scanner. What is the best way to configure this? Yes, scanning single channels is not what the scanner is ma...

Re: Airspy HF+ Discovery

I have been doing some antenna-tests with the 'discovery' and it is quite impressive what you can pull from this thing :)

Re: Frequency Scanner Plugin config

A late reply, but still :) Click the big red X to permanently lock out a channel from the scan (It will be listed in the frequencies.xml file in the section of excluded frequencies) If it is a channel that has a constant carrier, then it should already be skipped while scanning though, as the scanne...

Re: Antenna location question

Lots of experiments later and I've reached a conclusion: Higher indoor location beats lower outdoor location every time (At least in the building I am in) It hasn't mattered what type of antenne, or how it was placed, they all responded the same way; height being more important than inside vs outsid...

Re: Full disc weather satellite images from GK-2A

There is just one word: COOL! :)

So a tin-can, a short string of copper, and a sat-dish... is basically all that is required?

Switch-mode noise?

Is this 'switch-mode' noise? 'Switch-mode' noise as in; Some kind of device turning itself ON and OFF continuously, causing the 3 thin vertical lines on the spectrum. It's not 1 single frequency, but the 3 thin lines as you can see. However, when the 3 thin lines are thought of as 1 signal (For exam...

Re: 'the Buzzer' with an unusual issue

I don't know its broadcast-location.

'the Buzzer' with an unusual issue

I have never ever heard the Russian 'the buzzer' do anything but buzz, until tonight :) It began pitching its tone all over the place and basically sounded like it had fallen completely apart. It is probably just a technical glitch at the Russian military broadcast-center (Or whoever/whereever is br...
