Antenna cable guides?

I am just starting out and am looking to understand how different cable lengths and ohms impact your signal; also when, where and why you should use transformers.

Any recommendations for some quick reading / YouTube'n?

Yes, this could be an excellent idea! We already discuss this idea in the past: in Artemis Mk.2 was a nightmare because of the entirely different programming languages (Python and VB). With Artemis Mk.3 the story is completely different. Unfortunately, we discussed this feature during the launch of Artemis 3 and we were literally swamped with bug fixing and website problems. Nowadays the situation is way more stable and so we can resuscitate the idea. Returning to what you proposed: it is worth to mention also a work from Randaller (https://github.com/randaller/cnn-rtlsdr) that take advantage of deep learning to distinguish among different signals. This is a nice alternative but, thanks to José, we know that the code of Baliksjosay, wich use hashes generated from sFF transform (https://github.com/baliksjosay/audio_recogition_system) is working with radio signals. Now, a fair question could be the effective reliability (but this is probably directly related to the quality of the database). Anyway: stay tuned! Highly chances to have good news from us.

OK its working now. This may help @jamesbond, I went back and read the steps in rtl-sdr quick start guide and saw the note about requiring .NET 4.6 so I followed the link and downloaded .NET 4.7 from Microsoft site. I then and realised that I hadn't run "install-rtlsdr" and followed that process which probably has not necessary because the driver was not changed during the process (just re-installed). Also should mention that I'm running Win 7 SP1. So I suspect my real issue was not having an updated .NET version. Listening to solid FM signal right now. Good luck @jamesbond.
I have rtlsdr.dll in the sdrsharp folder and i'm not accidentally installing drivers to the wrong usb device.
