Amateur radio operating protocol is nothing like what is used in the US military. That "case" might have been valid prior to WWII but that time period was 67 and more years ago. Now, with Morse as deeply buried as its creators and military electronics too secret to be entrusted to soldiers and sailors who haven't been vetted for security clearances, we're yesterday's news in the E ring. I'm not sure what you mean by "Morse as deeply buried as its creators". I would suggest you borrow a 'communications receiver' that can tune in the HF spectrum OTHER than amateur radio band allocations. For one thing, the US military had all but abandoned morse code mode before 1953 for any mass-volume messaging connecting North America to military bases around the rest of the world. For another thing, the US military has abandoned HF for any mass- volume messaging and now uses secure military communications satellites, troposcatter, and the DSN (Digital Switched Network) for 24/7 communications. DSN has very robust security and is the major system of 'flash' alerts to land bases. Alerts for submarines (to listen to HF thru microwaves for the main message) are slow-speed encrypted data at VLF that can be received while submerged. The US military still keeps HF radios on a standby basis but only uses them for periodic operational checks. MARS is not a part of the daily US military messaging routine, although it is much closer to the use of operations protocol than amateurs. We hams continue to use Morse Code on the air - extensively, too! Please define "extensively" (with or without exclamation mark). No one has stated or implied that amateur use of morse code was not "extensive." In an unofficial poll at the ARRL website some time ago, #1 communications mode on amateur bands was voice. MARS is running Morse Code nets again, on an experimental basis. Military Affiliate Radio System mission was changed about five years ago to act in accord with other US government agencies to (ostensibly) link them together. Army MARS Hq is at Fort Huachuca, AZ, the same military base that houses the Army Military Intelligence training facilities. It's true that Morse Code has all but been eliminated by the US military for its own communications uses. That is not true. For routine tactical or strategic communications the US military has abandoned morse code. The M.I. school at Fort Huachuca still trains some in morse code signal intercept analysis but that is NOT communications per se. To attempt stating that SIGINT operations "use morse code" is like saying the Army still uses muskets and Revolutionary War uniforms because one Army unit in Washington, DC, has them for ceremonial duties. That's no surprise, even though Morse Code was used extensively by the US military in both World Wars, Korea, and Vietnam. Morse code was used "extensively" in World War ONE. In that 1914 to 1918 period voice communications was relegated to wireline communications circuits. Teleprinter circuits had already been established before the US entry into WWII, including its use on USN ships (see the 'SIGABA' descriptions on various websites for online encryption capability over teleprinter as early as 1940). As a soldier during and just after the Korean War, doing mass- volume communications via HF, I can assure you that morse code was NOT used for such communications about logistics or military planning plus (in a secondary basis) broadcasting news and 'health and welfare' messages carried for the Red Cross and other agencies to military members. The vast majority of communications carried on during the recognized active period of US involvement in Vietnam was voice and teleprinter. Like the Korean War, the Vietnam War was not a 'true' war yet service members were killed or wounded as a part of that actual warfare. During the prosecution of the Korean War, the US military routinely handled about a quarter million messages a month through military facilities. That was nearly doubled for the Vietnam War. Morse code communications MIGHT have been used in rare instances for both wars but its role was so minor as to be discounted compared to the MASS of messaging needed to maintain troops and equipment far from the USA. All of that military communications information is public and available to anyone who cares to look for it. I would suggest the U.S. Army Center For Military History as a starting point for very detailed historical accounts of the US Army since the Revolutionary War. But that doesn't mean hams should stop using Morse Code. NOBODY has said "hams should stop using" it. Please try to restrain generating another sub-thread about it. Please try to educate yourself about radio uses outside of amateur radio as described other than the ARRL publications or website. In order to EDUCATE THE PUBLIC, I would suggest channeling your promotion OUTSIDE of amateur radio venues. The general public and lawmakers don't much look into ham radio venues. AF6AY |

However, a lot of it seems to have gone more than a little OT (which doesn't surprise me and is actually quite interesting, so don't consider it a moan..!) But.. what are the thoughts on my original point, that of the differences in attitude of the authorities in the US and UK about protection from interference from commercial operators using frequencies within the amateur bands..? It seems to me, unless I've misunderstood, that in the US you can still claim a certain degree of protection from other users, whereas here we can't. 73 Ivor G6URP |

It seems to me, unless I've misunderstood, that in the US you can still claim a certain degree of protection from other users, whereas here we can't. The following is just an informal observation... Here in the USA, we have two regulatory agencies for radio: FCC, which does non-government radio, and NTIA, which does government/military radio. NTIA trumps FCC, of course. The radar-interference case mentioned elsewhere in this thread clearly shows who has priority on the band in question. But your question is about *commercial* (nongovernment) users/ intruders into the amateur bands, where such use is not part of the regulations. In theory, those intruders are breaking the law and should be removed by the FCC. In practice, the FCC is complaint-driven, which means amateurs must identify the intruder and complain to the FCC. Helping with such complaints is one of the major functions of the ARRL and its legal department. But simply complaining to FCC does not mean the problem will be solved, because FCC's resources are very limited. The motorsports story referred to required a lot of work on the part of the ARRL and the amateurs involved. 73 de Jim, N2EY |

The epidemic of unlawful CB operations of the 1970s and 80s - for which most of the world's governments never forgave the US - and an unfortunate shift in regard to what the government's obligations were - changed all that. Notwithstanding the historical precedents of military-civilian sharing of frequency bands, granting commercial interests licenses to operate in the amateur bands is basic bad regulatory policy. All of us old-time regulation professionals knew that as an article of faith. The new crop is guided more by the buck (or the Euro, or the quid) than by what good regulatory policy is. As far as the military goes, I learned early in the game that de facto the military of any country can operate on any frequency that it so desires if (1) it doesn't interfere with anything operating in that country and it (2) doesn't identify. If it wants to play the gentleman game the country will notify the operation to the ITU Radiocommunications Bureau (ITU-R) which now does what the International Frequency Registration Bureau (IFRB) did before ITU reorganization. Whether the information is accurate or not is an exercise left for the listener. -- 73 de K2ASP - Phil Kane From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon e-mail: k2asp [at] arrl [dot] net |

My friend Colin G3USA (great callsign, eh..!) tells me that in his early days on air in the 60's an amateur could expect to be regularly visited by an officer of the Radio Investigation Service who would check your logbook and that you knew how to use a wavemeter for example. In my 25 years of being licensed I've never been inspected once. 73 Ivor G6URP |

Ah, thanks. However, over here we do have "legal" intrusions into some of
the amateur bands, most are in the microwave region, notably 10GHz, where we lost a sizeable chunk a while back. The main one though is 431-432 MHz which is not available for use within 100km of Charing Cross (central London) and also for some distance around the military radar installation at Fylingdales in Yorkshire. In the London area I believe it's allocated to taxis of all things..! There isn't a lot of amateur activity in that segment, I think some wide-split repeaters may have inputs or outputs there but generally it's a low-occupancy segment of the band, so all in all it's not a major hassle. It's the principle of the thing that annoys me, though. Even where we are primary users, such as 2m, we can claim *no* protection from interference, even if the cause of said interference shouldn't be there. 73 Ivor G6URP The main problem in the UK is not the commercial use of 431-432 in the London area, rather the proliferation of licence exempt low power devices. Everything from key fobs to weather stations and tower crane anti-collision systems. They are popping up quite legally all over 70cms. Even one 70cms repeater was ordered off the air because it was stopping people from remotely opening their car doors in a nearby carpark! The UK has a Pave Paws derivative at Fylingdales at that caused a ban on new repeater applications in 70cms, the military being worried about the increase in noise floor that additional signals would introduce. 73 Jeff |
