So, there are more people on HF than 2m/70cm?
Definitely! That's why we are encouraging you to get your General class license so you can really experience the Amateur bands.
2m/70cm is mostly repeaters and there are some club repeaters there you can join in on. There is also IRLP which are internet linked repeaters and lets you link up other IRLP repeaters domestically and worldwide by simply entering a 4 digit number on your mic keypad and your in.
Other than that, there is not much SSB propagation on 2m/70cm. You have to wait for a 10 meter opening and then you are limited to a small portion of that band.
If you are confidant you can pass the Tech class, than with just a little more effort, you can pass the General tests as well. Do this now while you are still in study mode.
Good luck, 73
