Why do we need to know calling frequencies?
In fact, knowing calling frequencies such as 2-meter simplex calling frequency is a typical question on the Technician license test in the US. Making contacts on VHF and UHF bands is often more difficult (simplex or also weak signal that is) due to various propagation factors and the size of the band. So, calling frequencies are well used.
What is a calling frequency list?
A calling frequency list includes not only the modes but adds specific activities (expeditions, power levels) as commonly practiced. For new hams who are likely to get started in local VHF/UHF operation, the national calling frequencies to be concerned with are 2m and 70cm FM simplex (non-repeater).
What is a national calling frequency in the USA?

Why is it so difficult to make contacts on VHF and UHF?
Making contacts on VHF and UHF bands is often more difficult (simplex or also weak signal that is) due to various propagation factors and the size of the band. So, calling frequencies are well used. For example, on 2-meters, you can agree to meet someone on 146.52 (2 meter simplex FM calling frequency) and then when contact is made QSY to some other open frequency. It is not polite to tie up the calling frequency.
