Here it is 'sweeping' in from a lower frequency: https://vgy.me/bb9hsj.png .
Prior to the above image it did the same sort of 'sweep' a couple of times. I wasn't initially paying much attention to it as I was trying to capture audio of another signal.
It kept going for at least 30 minutes, the signal strength did not appear to vary, however I did not see how it finished.
There are some seriously strange radio transmission recordings to be found on Shortwave Odds & Sods Transmissions 2. Check out the one called UNID 11980 USB 2244z-2310 06-03-14. I have absolutely no idea what that might be, and would guess some sort of interference, but from what?
Sounds like someone has a Part 15 type FM transmitter connected to their phone. Something like this: https://www.amazon.com/JETech-Wireless-Transmitter-Phones-Charger/dp/B00URUJWPW/
You're first hearing interference from the USB charger circuit. Then someone starts playback on a mobile device.
Trying to triangulate a signal on a bearing? I was going to try this android app, but haven't had a chance yet:

You know what I find kinda funny? When I change the link from .co.uk to .com, I get the exact same product, and almost the exact same price number (£63.69 vs $64.95 US), but £63.69 is is equal to about $86.50 US. But thank you - it's still a lot less than I thought!

Okay. Here's a couple bits. Freenode is a fine network choice. You will need to do a few things:
- register your nickname
- consider a shorter channel name (#signalID ?)
- register the channel
- Run an irc client on an always-connected box you can connect in to. You are expected to idle in a channel that you admin and scroll back on messages while you were away.
It's the folding dipole antenna that comes with the complete package offered on amazon, though not fully extended. As for the low noise floor, I just adjusted the gain on SDR# like a responsible adult.
