It's to serve as an upgrade incentive. Not everyone aspires to run high power. Is it more difficult to understand how to operate on 3524 than on 3526? Of course not. Neither is it more difficult to understand how to operate a 100 watt transmitter than a 50 watt transmitter. But under your system, a Class B licensee could not legally operate a 100 watt transmitter. RF exposure, you say? The RF exposure hazard (in the high gain direction) from a 50 watt UHF transmitter with a high gain antenna is far more than that from a 100 watt HF transmitter with a low-gain antenna at the same distance. Yet under your system, a Class B licensee could legally operate a 50 watt UHF transmitter and high-gain antenna, but not not legally operate a 100 watt transmitter with low gain antenna. 73 de Jim, N2EY |

oups.com... I missed where you explained why the bands needed to be divided by class. It's to serve as an upgrade incentive. Not everyone aspires to run high power. When I upgraded from Conditional to Extra (Advanced was closed) in 1963 I didn't need any spiffy new freqs or higher power to motivate me. Sounds like giving lollipops to children if they'll first eat their spinach. Is it more difficult to understand how to operate on 3524 than on 3526? Of course not. Good answer! 73, de Hans, K0HB Grand Exalted Liberator of the Electric Smoke |

So what you're -really- talking about are low-power and a high-power license classes? ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

No. If you look at K0HB's license-structure idea, the main (in fact the *only* difference in operating privileges between his Class A and Class B licenses is the power allowed. Class A gets full 1500 W Class B gets 50 W Hans' idea is that by limiting Class B to 50 W, the RF exposure questions can be eliminated, or at least greatly reduced. But the fact is that 50 W can still be an RF exposure hazard on some frequencies (UHF in particular) if a high gain antenna is used. Deciding that the power level of 50 W is acceptable for Class B, but 100 W is not, is just a matter of judgement. It's the same kind of judgement as saying that 3500-3525 kHz is not allowed for all license classes. |

The only significant difference between Class A and Classes B & C was that Class A had the additional privilege of using A3 on 3.9-4.0 and 14.150-14.250 MHz. That's about it. Classes B & C were identical in priveliges; the only distinction was that Class C had looser requirements for testing purposes to accomodate military or CCC personel, people with disabilities or living in remote geographic locations, etc. Oh yeah..... if anyone wants a scan of an ad for the Hallicrafter's "Skyrider Diversity" let me know.

But you have to understand "the rest of the story"... In 1940, the HF/MF amateur bands in the US were 160, 80/75, 40, 20 and 10 meters. 30, 17, 15, and 12 meters were not allocated to amateurs. On top of that, the 40 meter band was all-Morse Code. No 'phone allowed at all. So a Class B or C amateur's 'phone options were 160 meters, 10 meters, and VHF/UHF (5 meters, 2-1/2 meters, 1-1/4 meters....) Classes B & C were identical in priveliges; the only distinction was that Class C had looser requirements for testing purposes to accomodate military or CCC personel, people with disabilities or living in remote geographic locations, etc. Yep - a Class C was just a Class B given by mail. A volunteer examiner gave the code test and proctored the written test (but FCC marked the written test). However, again there's "the rest of the story": Class C was issued conditionally. If the holder of a Class C license moved to within the required distance of an FCC exam point, left the military or CCC, or recovered from the disability, s/he had 90 days to be retested by FCC - or lose the license. Class A testing was only available from an FCC examiner or certain specially-designated FCC representatives. Class A also required at least one year experience as a Class B or C If a Class C ham went for the Class A license, s/he first had to retake and pass the Class B exam (code and written) at an FCC exam session before being allowed to try the Class A. --- The "ABC" system was in place from 1933 to 1951, including WW2. (Although FCC suspended all amateur station licenses during WW2, they still conducted operator license test sessions, and you could get an amateur radio license all through the war. There just weren't any legal amateur radio stations for you to operate). -- A piece of amateur radio history that few recall nowadays is how the ABC system came to be replaced by the Novice/Technician/General/Conditional/Advanced/Extra system in 1951. That 1951 multiclass system is the basis of the current license system. Oh yeah..... if anyone wants a scan of an ad for the Hallicrafter's "Skyrider Diversity" let me know. Awesome looking radio! Awesome price, too! |
