It’s relatively cheap, and I don’t feel like spending big money on an actual digital scanner. Thank you.
This can be a very deep hole you can fall into easily. Tread carefully and do all your homework before spending money.
The XG-75 is single band. It'll only do one band. You will be limited to listening to traffic on that single band and no others.
They come stock with analog and P25 conventional only. All other features (P25 trunking, EDACS, OpenSky, etc) are all additional cost items. The radio doesn't necessarily include those features and you would need to make sure it had what you wanted. Adding it later is possible, but expensive (way more than a new digital scanner)
Programming software (RPM) is expensive.
Programming cable will be required.
Programming these sorts of radios is not as easy as a scanner. It's complex and has a lot of functions that need to be set up correctly.
On the other hand, the receivers are usually much better than a consumer scanner.
But you really need to consider all the costs and all the risks involved. If the radio doesn't have all the features you want, you'll end up adding them. P25 Trunking is a $950 (list price) option.
And any used radio you buy, consider that the battery is likely worn out and will need to be replaced. Antennas are usually beat to hell, too.
It's pretty rare that you can buy a used radio like this and come out ahead of just getting a new scanner.
