When the government finally got in on it, the amature licensing rules and qualifications were put in place to ensure that those on the air new what they were doing. At the time, most equipment was home made due to the unavailability of anything commercial and they wanted to ensure that armatures would know enough not to interfere with others and not kill themselves in the process. Remember spark gap? Could be very user unfriendly. "starman" wrote in message ... If the goal is to 'weed out' the undesirables, increasing the knowledge base of the technical test(s) would be a more useful gatekeeper than learning morse code. Knowing more about the technical aspects of the hobby might also encourage more construction and experimentation, which is (was) the primary reason why amateur radio was created. Actually, both of you are partially correct. Amateur radio has been around since radio was invented pretty much. What is now the commercial AM broadcast band was once amateur radio frequencies. The old ship to shore stuff was largely in the LW bands (spark gap, and later keyed-carrier CW). The "higher frequencies" were considered worthless. But as amateur experimentation continued, and it was found that higher frequencies could be very useful, the government (and international treaties) gradually reassigned those frequencies to other services. The amateurs were allowed to keep slivers of MW and SW bands for their continued use, and reasonably large sections of VHF and UHF bands. Much of the SHF bands (microwave) is still open to amateur use. I believe that pretty much everything above 1 terrahertz (1000 gigahertz) is amateur frequencies.. until they figure out how to effectively use them.. |
