Never has worked with WFM. It was not designed for NFM. {^_^}

There is a good reason for this. There are two oscillators that need correction. And the correction process is a nasty dance when you do not know what has to be corrected for the error you are seeing.

Unless you do it full screen you can move the cursor onto the background window and click there. Then any keyboard bumps go to the desktop. {o.o}

Seconds in transit. (Don't forget the time zone corrections, the -700 and -400). They all refer to essentially the same time. {^_^}

I have a lot of rtlsdr dongles. My chief use for SDRSharp is to use one of those dongles that is on an FM Yagi with NEAR line of sight to Mt. Wilson where all the transmitters live. I use it for backg

It is known as a splash screen among programmers. It lets you know the program is started while it figures out all the data it needs before it can show it's GUI correctly. This includes searching for

Typically for a small loop antenna you want a very low input impedance. So you probably should consider both input noise voltage and input noise current in a common base or gate configuration. {o.o}

Seen worse.... Well, I have. I've always figured "if it conducts it radiates" ever since hanging a 15 meter 1/4 wave wire draped over a rafter in the attic with no ground and discovering it worked pre

#airspydiscovery

Well, to be fair to the guy consider that the need for amplification goes down with frequency because the loop becomes more efficient until it is on the rough order of 1/10 wavelength in diameter. But

#airspydiscovery

EEeeewwwwwwwww! {O.O}

#airspydiscovery

The high end of HF, nonetheless, is the end at which the natural noise is minimum. So you (may) need more gain there. The other choice is your main frequency range of interest. Pick a spot, usually to

#airspydiscovery

Adjust from low gain upwards until the SNR on weak signals stops improving on the highest frequency which is of interest. {^_^}

#airspydiscovery

Thank you for a good laugh. Of course it shows a low noise floor. It is an inefficient antenna. This is OK because ambient noise at HF, particularly low HF and below, is VERY high. The real observatio

That needs more study. And for BCB loop sticks the null is off the ends of the rod - so of course! I was thinking of the pattern of a loopstick antenna when I made my comment. The COIL part is perpend

I believe the ARRL handbook is a good beginner's way to come up to speed. I'd recommend it in your case. The pattern is, as has been noted, a figure 8 with the nulls in the plane of the loop. Looking

What do you see when you plug the disk in with another OS install up and running? If you see a lot of files it probably should work. If you see one file with a name that is the same as the file you bu

So that part of it is settled. Now, what do you know about the synthesizer in the AirSpy? (If it is a real AirSpy (VHF/UHF) forget about getting closer than about 7 Hz. That is the smallest step that
