The same goes for TV stations that use this frequency, and it can be quite limiting in this regard. The classic FM bands that we are used to hearing on standard and car radios travel via line of sight, and therefore are only transmitted 40-50 miles. This is where things get a little more interesting. Historically, they are known as shortwave bands – as in shortwave radios. If you are in search of the same at night, the best band for you to be using is 1.6-15MHz. However, the time of day can also have an impact on this.ĭuring the daylight hours, 15 to 27MHz is an excellent band if you are looking for long-distance communications. You will find that the majority of ham bands, as they are called, are found in the frequency that goes above the AM radio band (1.6MHz) to just below the citizen's band (27 MHz). This means that hams are able to operate from just above the AM broadcasting band to the microwave region, in the gigahertz range. The idea of the word hams coming from amateur radio hobbyists disrupting government signals is more exciting and, in my opinion, the more likely of the two. There is another theory that the word ham comes from a shortened version of amateur, but I feel like this one is a lot less fun.

As time has gone by, the full meaning of this phrase has been lost entirely.
The amateur radio users took this term and applied it to themselves, despite not fully understanding the meaning of it. The commercial operators, becoming increasingly frustrated by this, would refer to those causing the interference as hams. The issue with this is that the stations being used by amateurs were incredibly powerful, meaning that they could easily jam all the other operators in the area. This meant that government stations, ships, coastal stations, and amateur operators were all competing for signal time and priority on the waves. As this was quite early on in the life of the ham radio, it used a broad spark signal that occupied every station. However, in the beginning this form of communication was used by landline telegraphers who have left their offices in order to man coastal stations or had been sent to sea.
The ham radio started its journey in 1901, and since then has been subject to licensing laws and regulations.
