As I told you last summer, whether someone has passed the code test or not has no relevance. It's whether someone has passed the advanced test. Since it's a mix and match system, people can pass the advanced test without taking a code test. They can build all the transmitters all they want at that point, but since they haven't passed the code test they have no HF privileges. There is no "no code license" in Canada. There are two levels of license, and either one can be no-code. Michael VE2BVW |

There is an outfit that has kits to do exactly that. Also there was/is the Amqrp [http://www.amqrp.org/] DDS VFO daughter board. That with the PIC-el kit was a quick means for me to bootstrap into using PICs and DDS for my Rf perojects. In the past I've used micros but ahving the tools and a a really nice course on a specific one was a useful assist. Are we just too old? Never! Allison |

... Elecraft has several kits that build an advaned transceivers with microprocessors and digial pannels. The average hams do build them and when done can even fix them. I'm not so sure I'd call someone building an Elecraft an 'average ham.' Especially with the K2, there are enough parts in there that most people who build it are probably already seasoned kit builders. Indeed, there are even lists of hams out there who will assemble Elecrafts for other hams who _don't_ have the skills or desire to put the things together! Still, I think there are plenty of homebrewing opportunities available to hams (the ARRL's publication of "Experimental Methods in RF Design" last year bolsters this argument), just that a smaller percentage of hams than in prior years chose to avail themselves of the option. There will always be folks out there experimenting with radio -- look at how popular WiFi 'hacking' is and even low power FM! ----Joel Kolstad |

There are two levels of license, and either one can be no-code. I wasn't sure if the countries involved but my understanding was Canadian rules are similar to US in style and form. Other countries are beyond my knowledge. I'd expect from articles I've read and the calibar of those authors there are many that allow home built equipment and may even encourage it. Allison Kb1GMX When things were restructured here back in 1990, the basic test/license specifically forbade the use of homebuilt transmitters. It's only after one passes the advanced test that one can use homebuilt transmitters (and it allows for 1000watts input versus 250W for the basic license, and the control of repeaters). But his error is in reading the rules to mean that you have to have code to pass the advanced test, and thus to build transmitters. The code tests (back then there were both a 5 and 12wpm tests, now it's only 5wpm) were independent of the written tests. With no code test, but the advanced license, one has full privileges, though it all has to be above 30MHz. The code test(s) only add HF capability, whether you have the basic or advanced license. This is in contrast to the US model, where advancing did require a code test at some point. Up till 1990, of course anyone with a ham license here could build their own transmitter (and the only thing the advanced license gave was voice on HF). When I was licensed back in 1972, it was still called the Amateur Experimental Service, though that full name was dropped at some point without comment. The impression people had was that since few were building things, then this wouldn't affect many. But by making the written test simpler, it would "make it easier" for people to enter the hobby. I've not realy looked over what the test is like, but I sure had no problem passing the test back in 1972, when I was twelve. But ironically, if few are building things, those few won't be doing much damage even if they don't know what they are doing. Indeed, it's likely that only people who know what they are doing would be building, hence the state of the test shouldn't matter. I don't like the rule, since it does change the hobby, and institutionalizes a perception of the hobby. But like I said, code has nothing to do with whether or not someone can build their transmitter. Michael VE2BVW |

I have several homebrew QRP rigs that fit in the palm of my hand.
They're all HF...a couple even exceed 3w output. They make the FT817 seem like a bowling ball in the backpack. g 73 "Airy R.Bean" wrote in message ... Much of the negativity that the CBer-Masquerading-As-A-Radio-Ham emits when it is suggested to him that he should build his own rig comes from a complaint that it is not possible to miniaturise a rig to the sizes that are available from the Nipland CB suppliers, mainly Yaesu and Kenwood. But, surely, the size of a rig is irrelevant to anyone interested in technical performance? I wonder what size of rig is really acceptable to the _REAL_ Radio Ham when you consider that the RACAL RA17 was a large 19" rack model, and when you take into consideration the footprint of desktop PC's that have been welcomed so recently into a number of shacks? How about a foot print of between 12" and 18" square, with a height of about 3"? That would make a rig about the same size as a DVD player, again, an item of consumerist products that until recently was unknown but now is de rigeur - again pointing out the spurious argument put up against HB. In a box 18" square by 3" tall, we'd have enough room to manoeuvre and to experiment with circuit changes but without worrying that our Henley "Solon" soldering irons were going to melt a component other than the one we're currently dealing with. |

Well done, that man!
I bet it's difficult, though, to experiment with the circuit configuration of any of them! "Brian - KB9BVN" wrote in message ink.net...
