Hi,
I am just dipping my toe into the world of SDR and this looks like a great forum to pick up tome tips.
I have bought a nooelec NESDR Smartee V2 as a start.
Unfortunately i live in a ground floor apartment and external antennae are not an option. I wish I had thought about that before i moved in but I have not had a valid Ham licence for 20 years and receiving RF was not in my mind. So, I am using the bundled VHF antenna that came with the nooelec on my desk.
Anyway, while trying out CubicSDR on my Macbook Pro, I was listening around the VHF Airband and noticed a continuous tone on 117.450.
I don't know what it is, and it doesn't matter for for now. I'm sure it is something spurious.
I noticed it at the left edge of the waterfall and it was a reasonably good signal.
But when I scrolled the window sideways to centre that frequency, it went off completely.
So on the far left, it is strongest, but if I move it closer to the centre by a 12th of the width of the window (The window is showing the full width that the nooelec can do, about 2mhz), it has gone completely. I see the signal get weaker as I move it.
What does this indicate? I have a RSP1A on order and it will be interesting to compare the signal on both.
Does it show a software setting problem or is it a limitation of the hardware?
