Just ordered the ARRL Technician study manual and am planning on getting my Tech license. My goals for HAM are simple: to have a means of emergency communications when the phones, cell towers, internet, etc. are disabled due to weather or other reasons. My questions are, Can I do this with VHF only, or do I need HF or UHF? I understand that HF has more range at low power, but can I use voice with a Tech or will I need General or Extra?
