It doesn't cover the full HF bands. if that is what you want. It covers 10m though and upwards. Sheila you need to decide if you want to listen to HF or VHF. If it's worldwide then it's HF you need. HF is from 1.8mhz to 30mhz.
My two pence worth
Unfortunately a lot of the interesting stuff is now gone from VHF and UHF FM.
Sheila, if you want to listen to a very wide radio spectrum, I’d suggest getting one of the Sdrplay units. You’ll get from LF through to microwave frequencies. You will need to connect it to a computer, but having used one in the past, I can say that they work very well. Obviously this is receive only and you’ll also need antennas to suit various bands.
Ill give you a shout on D-Star and you can reply on Fusion. I've no idea what'll happen but I doubt it'll go well!
You don't know what your missing, the dmr network in Scotland is expanding daily the only areas that are a bit uncovered is Glasgow but that's Down to not being able to find a suitable central location for a repeater, in this area the uhf coverage is good (most areas you can get in with a handheld on low power)
Now we really will get mixed up, MM7DXC or MM0DXC 🤔😂
