![]() "Michael Coslo" wrote in message ... [snip] Thanks for the correction Jim. I should have stated that what I don't like on the tests is questions about what particular frequencies you are allowed to operate on by your class. Yet there are times such as mobile or portable operation that we don't have that band chart with us. So it's nice to know our frequencies. Of course taking into account the bandwidth of the transmitted signal, another question that would be better on the test than the simple statement of frequencies. I definitely agree that this should be a possible test question as one can be out of band simply due to the width of the signal. A lot of people don't understand this until they get "dinged" so to speak. When I teach a class, I try to emphasize this. Dee, N8UZE |

For example my Icom IC-V82 2m handie will transmit anywhere from 136-174 MHz. This was apparently necessary to allow it to operate on the US 2m band 144-148 MHz. Here in Region 1 (UK) we only have 144-146 on 2m so so in order to keep the warranty intact, I asked the importers to modify it for the US band when I bought it, as I travel there on holiday regularly. They told me that opening it up to 134-174 was the only way it could be done, apparently the firmware in US versions that cover 144-148 only is different. 73 Ivor G6URP |

So it's nice to know our frequencies. how many mobiles will premit out of band op Dee? none of mine will All HF rigs that I have permit one to set and transmit SSB in the CW/Data portion. That is operating out of band. Happened to a lot of continental US folks last weekend in the CQ WW contest. I suppose they got excited and weren't paying attention to the frequency readout. only on HF can this be an issue since only hthere does the rules contiue the insanity ofparts of bands to deferent class (amoug the classes we still issue) You are overlooking the splits by mode. For example it is against FCC rules for continental US stations to transmit any voice mode in the CW/DATA portion. Of course taking into account the bandwidth of the transmitted signal, another question that would be better on the test than the simple statement of frequencies. I definitely agree that this should be a possible test question as one can be out of band simply due to the width of the signal.

I thought it was such a question Even if there is a question in the pool, it may not show up in an actual test. Basically the pool needs to contain several questions of this type to insure that one does show up on the actual test taken. Dee, N8UZE |

All HF rigs that I have permit one to set and transmit SSB in the CW/Data portion. All the HF amateur rigs I have seen will also permit one to transmit data modes in the 'phone/image subbands, which is also against US regs. Some will permit things like too-wide-for-the-regs FM on HF, too. That is operating out of band. Happened to a lot of continental US folks last weekend in the CQ WW contest. I suppose they got excited and weren't paying attention to the frequency readout. Or they don't know the rules well enough to apply them all the time. For example it is against FCC rules for continental US stations to transmit any voice mode in the CW/DATA portion. Whether we like it or not, subbands-by-license-class are a reality for FCC-licensed amateurs. That's a reality which isn't going to change soon, because FCC has repeatedly denied all proposals to eliminate subbands-by-mode or subbands-by-license-class on the HF amateur radio bands. We might someday go to subbands-by-bandwidth, if someone can come up with a reasonable proposal, but the situation won't change much if that happens. We'll still have the case of 'you can't transmit that mode on this frequency'. There's also the fact that we US amateurs - all of us - are allowed by the regs to design, build, repair and modify our rigs, and they don't have to be formally type-accepted or certified. So it makes sense to require us to know the regs rather than expecting our rigs to prevent our mistakes. Even if there is a question in the pool, it may not show up in an actual test. Basically the pool needs to contain several questions of this type to insure that one does show up on the actual test taken. Even if the question shows up on the test, the person can get it wrong. IMHO, one of the fundamental weaknesses of the written tests today is that all subjects and questions are lumped together so that a person can have huge holes in their knowledge yet still pass. This is of particular concern because the holes can be in subjects like safety and regulations. I think it would be better if each test were broken down into subelements-by-subject, and marked in such a way that you'd need a passing grade in each subelement to pass the whole exam. 73 de Jim, N2EY |

An interesting thought. Or maybe this is already a feature of the new rigs. I wouldn't know, not having bought any HF equipment in this century. I acquired an Elecraft K2/100 about 18 months ago. It has been augmented by the K3 now. Both are top-of-the-line HF rigs in kit or modular form (think of a Heathkit on steroids). Neither has the feature that you are describing. -- 73 de K2ASP - Phil Kane From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon e-mail: k2asp [at] arrl [dot] net |

The new generation of HF transceivers -- the ones that have quite a bit of computing ability built in -- do they have the ability to enforce sub-bands? I don't know of any that do, in terms of subbands-by-mode or subbands- by-license-class. But I don't think it would be a big feat of software engineering to have a lookup table that compared the mode selection with the transmit frequency, and allowed transmission only if the selection was in the lookup table. Certainly they *could* have that ability, since they already "know" the band edges and in most cases won't allow you to transmit completely outside a band allocation, but why not support the next step and not allow SSB in the CW band? As N8UZE points out, this would limit flexibility, because all sorts of "soundcard data modes" are often implemented by putting the rig in SSB mode and feeding audio into it. This may become less of a problem as more rigs incorporate data modes internally. (The Elecraft K3 can send and receive RTTY and PSK31 without a computer, monitor, or keyboard). I don't think that most folks who find themselves doing something stupid like using SSB outside of the US sub-bands do so because they don't know the regulations. They get caught up in the excitement of a contest or chasing DX or their mind slips out of gear, and when they realize what they've just done they feel about two inches tall. With all due respect, if someone forgets the regs by being caught up in the excitement, they really don't know them in a practical sense. I would like to see the flexibility in a piece of equipment that I just shelled out big bucks for to keep me from doing this, while at the same time giving me the flexibility to program the segments that apply to my license class or if I take the rig to a different location where the rules are different. The second problem is that, for flexibility, you'd have to include the ability to defeat/disable the feature. Which means it could be left in the off position unintentionally, and provide no protection. 73 de Jim, N2EY |
