Are we in danger of being the last generation of hams? (And if we
are, what can we do to eliminate that danger?) First, a disclaimer. I'm into my fifth decade of being a licensed amateur, and figure I'm good for 3 or 4 more sunspot cycles of fun. I love amateur radio. But I worry sometimes. Our service will only continue to exist so long as the majority of the worlds national governments believe that we bring value to the public in exchange for the incredibly valuable RF spectrum that is entrusted to our use. I think if the members of ITU collectively asked "Are the hams of the world doing anything which justifies their generous chunks assigned spectrum?" the honest answer would be "Probably not." What are we going to do about that? 73, de Hans, K0HB |

@y80g2000hsf.googlegroups.com: Our service will only continue to exist so long as the majority of the worlds national governments believe that we bring value to the public in exchange for the incredibly valuable RF spectrum that is entrusted to our use. That might have been true before 2000, but isn't true today. Some spectrum would be lost to services who are interested in VHF/UHF and above. But, noone wants HF any more, as is self evident by the lack of traffic across HF outside the ham bands. Even the broadcasters, like BBC of all entities, have reduced transmissions drastically across HF and migrated to internet servers. Check out http://www.bbc.co.uk/radio. You can listen to ALL the BBC radio stations from that webpage, live! The internet is really cheap to broadcast to...much cheaper than that monster out in the country with the big Sterba curtains. VOA is dead...RAI is dead...Radio Switzerland is dead. (http://www.eviva.ch/ if you like Swiss accordian music...(c ![]() Berner Oberland (http://www.beo.ch) in Interlaken, Bernese Oberland on beautiful Lake of Thun broadcasts 24/7 to the world. What amuses me is ARRL and the other lobbies haven't just been inundating ITU for the unused parts of HF. They can alwasy steal them back for WW3, if it lasts over 5 days...which I doubt.

Maybe it's not vulnerable, or maybe it is, but compared to the massive amount of VHF/ UHF spectrum we could lose, I consider HF an insignificant issue. So I pose my question again.....

That might have been true before 2000, but isn't true today. *Some spectrum would be lost to services who are interested in VHF/UHF and above. *But, noone wants HF any more, as is self evident by the lack of traffic across HF outside the ham bands. MF/HF is only a minor fraction of our allocations. * In terms of how many kHz we have, yes. Except for 6 meters has more kHz than all of the 9 MF/HF bands plus the channels at 60 meters. Same for almost every amateur allocation above 30 MHz. But for some reason those HF/MF bands are considered extremely desirable by radio amateurs. Maybe it's not vulnerable, or maybe it is, but compared to the massive amount of VHF/ UHF spectrum we could lose, I consider HF an insignificant issue. Which would you rather lose - 1 MHz of the 1296 MHz band, or all of 160, 40, 20, 30 and 17 meter bands? Same amount of bandwidth... So I pose my question again..... *"What are we going to do about that?" The first thing is to simply *use* that spectrum. The very best argument for reassignment of spectrum is that the folks who have it aren't using it. or aren't using much of it. That argument was one reason we lost 220-222 MHz: the folks who wanted it were able to convince FCC that we hams could fit all of our 220-222 activities into 222-225. But you can't force amateurs to operate on certain bands. They can be encouraged, but not forced. So the question becomes "what will make the VHF/UHF amateur bands more attractive to hams?" Perhaps a new generation of near-geosynchronous amateur satellites would attract more activity. Or the deployment of a highspeed linked repeater network. But those things require sizable infrastructure investments by amateurs. --- Perhaps, when we speak of those VHF/UHF bands, we're seeing history repeat itself. In 1912, amateurs were legislated to "200 Meters And Down", meaning they were legislated off what were then considered to be the most- useful wavelengths. After the 1912 laws went into effect, amateurs could get station licenses for any of the 'shortwaves' simply for the asking. But once those amateurs showed how useful those 'shortwaves' were, others followed, and by 1924 or so amateurs were confined to certain bands. No longer could amateurs simply pick a wave and get a license to use it. Then in 1927 came the "1929 rules", which significantly narrowed some of the existing bands. 40 meters had been 7000 - 8000 kHz before the 1929 rules, but once they went into effect, the band was 7000 - 7300. 20 meters went from 14000 - 16000 to 14000 - 14400. There were other changes such as requiring stable and clean signals. Some said that those 1929 rules would strangle amateur radio, and would soon kill it off due to overcrowding and the expense/complexity of a "1929 transmitter". But exactly the opposite happened, because in the years after the 1929 rules, the number of US hams almost tripled and the technology used took great leaps forward. We hams got our enormous VHF/UHF allocations after WW2, when much of it was considered relatively useless, or at least not as useful as the lower frequencies. That's all changed in the past couple of decades. Perhaps it's 1929 all over again in some ways. 73 de Jim, N2EY |

I didn't know this was so dictated. If amateurs want to keep something in radio, they have to continually fight for it; just because they got some allocations once doesn't mean it is forever. In the last half century, amateur radio worldwide has GAINED allocations, not lost. Begin with WARC-79 decisions... So I pose my question again..... ?"What are we going to do about that?" The first thing is to simply *use* that spectrum. The very best argument for reassignment of spectrum is that the folks who have it aren't using it. or aren't using much of it. How does "*use*" of line-of-sight get publicized nationally? The NTIS has a specific EM Survey mobile unit which has been used to take readings of certain areas of the United States over an extremely wide range of frequencies. Those surveys are available to the public and each one is extensive, technically explicit. Other than "popular activities" described in amateur radio interest periodicals, the use of line-of-sight frequencies is mentioned only in regards to an already-allocated radio service in trade journals. That argument was one reason we lost 220-222 MHz: the folks who wanted it were able to convince FCC that we hams could fit all of our 220-222 activities into 222-225. "220" wasn't the only amateur band in dispute in the last half century in the USA. The politics of the various disputes can't be simplistically interpreted. As I recall, not a user of "220" at the time, the ARRL did not argue effectively enough for its retention to convince the FCC. But you can't force amateurs to operate on certain bands. They can be encouraged, but not forced. Yes, they can be forced. See "200 Meters and down." So the question becomes "what will make the VHF/UHF amateur bands more attractive to hams?" I wasn't aware that the ham bands above 30 MHz were not attractive. Radio equipment manufacturers are continually supplying radios and advertising VHF-and-up radios, have been for years. There's obviously a market for them as witness the continued advertising campaign waged with high monetary values. Since the inception of the no-code-test Technician class license 16 years ago, the vast majority of newcomers in the USA have entered amateur radio in the "world above 30 MHz." The Technician class has become - easily - the most numerous of all US amateur radio classes. No-code-test Technicians were banned from privileges below 30 MHz in the USA. "Techs" continue being newcomers despite cessation of morse code testing in the USA for amateurs. The migration to VHF and above in amateur radio is not confined to the USA. JARL and Japanese electronics industry have developed D-Star specifically for digital modes on VHF and above. AOR in Japan has one digital voice adapter for voice-bandwidth radios and another one from Germany has been described in the April QST issue this year. While US HF-only hams may shun digital anything on "their" bands, such is readily useable on VHF and above with no basic changes. Perhaps a new generation of near-geosynchronous amateur satellites would attract more activity. Perhaps it would be prudent to take a good look around at the activity at VHF and above that is going on today? Or the deployment of a highspeed linked repeater network. But those things require sizable infrastructure investments by amateurs. Is that a necessity? In 1977 I was shown the start of what would grow into the present-day Condor Net on the "220" band, operating in three states (CA, NV, AZ) and capable of being tone-coded-linking from one repeater to any other repeater. That was without using conventional digital logic or the ubiquitous microprocessor. Sizeable investment by amateurs? Yes, but also willingly done. Well done, I might add. The latest ARRL Repeater Directory shows an enormity of repeaters ("sizeable infrastructure investments"), most of them public-access, installed and operated by radio amateurs. Repeaters have been put into place all over the USA in the last three decades plus. Even without repeaters, the use of VHF-UHF and even low microwaves by radio amateurs has become sizeable in urban areas of the USA. --- We hams got our enormous VHF/UHF allocations after WW2, when much of it was considered relatively useless, or at least not as useful as the lower frequencies. That's all changed in the past couple of decades. Not being a licensed radio amateur right after WWII, I was unaware that "VHF/UHF" was "useless." Edwin Armstrong pioneered FM broadcasting there in the 1930s. Public safety radio started the use it in the last 1930s, finding it very useful compared to the old HF radios a few agencies had. The US military was already using low VHF in the 1930s and would continue that with the famed "walkie-talkie" of WWII. The fledgling TV broadcast industry and their equipment makers had already standardized on low-VHF frequencies in the 1930s (via the "first" NTSC). The US military switched to low-VHF FM radios for vehicular operation en masse at the beginning of WWII...even the USN had its "TBS." Radar, a savior of tacticians in WWII, had to operate on UHF and microwaves, was predictably quite successful in that RF region. Still is. All of the preceding paragraph took place 7 decades ago, not a "couple" of them. Perhaps it's 1929 all over again in some ways. Perhaps too many of the HF persuasion are affected with ennui over their self-imposed limitations of radio use. I still see an unlimited vista of hope and adventure in the future. The state of the art of radio-electronics is constantly advancing. By the looks of things, it isn't about to stop anytime soon. Change keeps happening. Those who refuse to change, want their endless youthful discoveries to continue, want to close off amateur activities to what was long ago, will all mourn and wail over "losses." The rest of the world will continue without them, changing things to fit the new people, not the old ones. Those who want something will have to go out and WORK for it, DO something about it, not sit around and grouse about things not being the same. The new people will have earned theirs and the future will be different. I say good for them! 73, Len AF6AY PS: No "artifacts" were exploited or utilized on this text file upload. |

That's misdirection, Jim, and ignores the question "What are we going to do about that?" In 1912, amateurs were legislated to "200 Meters And Down", meaning they were legislated off what were then considered to be the most- useful wavelengths. So maybe the answer is that the FCC should craft a new challenge of similar magnitude to stimulate the Amateur Radio service to a new golden age, similar to that which followed the 200-meters-and-down challenge. How about this, for a two step approach? 1) Institute a new "top" license class with a "technical quotient" about 3 times as challenging as the current Extra class license, and keep the question pool secret. Holders of this license could experiment on any amateur frequency (with the usual "no deliberate interference" caveat) with any modulation scheme or information encoding scheme without special authorization or STA. 2) Starting 10 years from the effective date of the R&O, require that the following band segments can only be used with modulation types and information coding schemes which were invented in the previous 15 years. All of 160M. 3550-3600KHz. 3900-4000KHz. 7050-7150KHz. 7250-7300KHz. 14050-14100KHz. 14300-14350KHz. 21050-21100KHZ. 21400-21450KHz. All of 10M. 146-148MHz. 222-225MHz. All bands above 432MHz. |

That's misdirection, Jim, and ignores the question "What are we going to do about that?" It's not misdirection, Hans. It's a plain and simple question, meant to focus on the fact that not all kHz are created equal. In 1912, amateurs were legislated to "200 Meters And Down", meaning they were legislated off what were then considered to be the most- useful wavelengths. So maybe the answer is that the FCC should craft a new challenge of similar magnitude to stimulate the Amateur Radio service to a new golden age, similar to that which followed the 200-meters-and-down challenge. Perhaps. How about this, for a two step approach? 1) Institute a new "top" license class with a "technical quotient" about 3 times as challenging as the current Extra class license, and keep the question pool secret. I like it! The only problem is, how would the question pool be kept secret? How could FCC be convinced, after a quarter-century of published Q&A pools and the VE system, that this new license class needed a different exam system than all the rest? *Holders of this license could experiment on any amateur frequency (with the usual "no deliberate interference" caveat) with any modulation scheme or information encoding scheme without special authorization or STA. The problem I see with that is, who defines 'experiment' or 'deliberate interference'? I could see the license being used as a way around mode-subband restrictions, rather than real experimentation. 2) Starting 10 years from the effective date of the R&O, require that the following band segments can only be used with modulation types and information coding schemes which were invented in the previous 15 years. *All of 160M. *3550-3600KHz. *3900-4000KHz. *7050-7150KHz. 7250-7300KHz. *14050-14100KHz. *14300-14350KHz. *21050-21100KHZ. 21400-21450KHz. *All of 10M. *146-148MHz. *222-225MHz. *All bands above 432MHz. Which means that 160, 10, 220 and all above 432 would no longer be available for the use of SSB, DSB, AM, FM, RTTY, AMTOR, PACTOR, SSTV, TV, PSK31, and CW. Plus considerable segments of the rest of the amateur bands would lose those modes as well. Not by voluntarily abandonment of old modes but by law. I don't think that's a good idea. Just because something isn't brand new doesn't mean it should be legislated off the air. 73 de Jim, N2EY |
