Absolutely! All governments I know of, including the US, UK, Australia and NZ, regard the radio frequency spectrum as a resource which they can lease bits of to paying customers. Licensed radio Amateurs have traditionally been allowed to play and experiment with quite large chunks of that radio spectrum which, 100 years ago, the governments had no idea what to do with. But technology has changed. The frequencies and bands available are finite; so those able to sell/lease chunks of it do so, basically to the highest bidder. Hams are lucky they don’t have to pay through the nose… Other users of the radio spectrum usually do pay a lot for the privilege, and of course they don’t have to study. only licensed Hams need to become (amateur) radio technicians! The original idea of an Amateur radio licence was a permit from the government to experiment and learn by doing things on assigned radio bands. 73 de David vk2dmh

I’m a lic. ham and it’s kind of seemingly nothing but a money thing, having a license (from those I’ve spoken with) for GMRS. What do you need to know? Apparently nothing at all! You just fill out an appl. send in enough money and you are given a license. Most of those I know with a GMRS license admit they don’t know the first thing about radios !

Comment on Screwdriver Antenna – Convenient Multi-Band HF Mobile Antenna by Admin

Sure, you can use an automatic ATU and a 9-foot CB whip, and that will tune between 40m (7 MHz) and 10m (28.5 MHz) or 6m (50 MHz) pretty easily. But it won’t be cheap, and at 80m (3.5 MHz) it will be pretty terribly inefficient… Most of your transmit power will be wasted as heat long before the signal gets out! However an automatic ATU like the SGC, Alinco or similar boxes at the base of around 50 feet of wire or more, with several 1/4 wave counterpoises and one or more copper earth/ground stakes can be pretty good as a low-profile HF antenna in the home. You can hang the wire as a sloper antenna or an inverted L antenna under a tall tree or other support.
