I'm a Technician looking to upgrade and trying to understand the practical differences in HF privileges. I know General class licensees get access to over 83% of all amateur HF bands, but what does that mean in real terms?

Specific questions:

• Can I operate phone/SSB on 20 meters as a General?
• What about digital modes like FT8 - are there restrictions for Techs?
• Emergency communications - do I need General for HF emergency nets?

Looking for practical examples of what I'll be able to do after upgrading that I can't do now.

General Class licensees can operate digital modes and SSB phone on HF bands below 28 MHz, including 20 meters which is excellent for DX work. Generals can operate all digital modes on HF, including FT8 - huge difference from Tech privileges!

For emergency communications, having access to most HF bands is almost a necessity for traffic handling, since amateur HF communications get through without failure during disasters. Winlink HF email system works nearly anywhere in the world with General privileges.

As Tech you're limited to CW on most HF bands and small phone/digital segments. General gives you digital modes and SSB phone on HF bands below 28 MHz - opens up the entire world! 20m SSB was what convinced me to upgrade.
