Why don't Real Hams you face the facts?

Yes, I agree!! Furthermore, I think, IMHO, that that is what this newsgroup
should continue to be about---the exchange of valuable information and the education of those less versed but definitely interested ones (people like me) in the ways of the firebottle. People who are intelligent enough to be interested in 50 year old (or more), 50 lb. (or more) pieces of radio equipment usually are intelligent enough to refrain from senseless flaming. Those with more neanderthal sloping foreheads are the ones who seem to knock what we do. There's ideas to be shared, and tips to be learned in keeping these fine old pieces of gear WORKING!! Is radio a great hobby? I sure think so. How about you? |

Actually, the neat thing is that current technology makes homebrewing more fun than ever! I can now build one hell of a nice receiver using DSP technology and doing most of the IF processing in the digital domain, using off the shelf stuff.

What I want right now, though, is a PLL on a chip that will take a simple BCD or binary encoded frequency, and produce an unmodulated carrier. I would be surprised if someone hasn't built something like that already using one of those Sanyo mask-programmed microprocessors with the PLL on the chip like a lot of CBs use today. Doesn't have to be a PLL, it could be DDS too, but I want a single chip synthesizer that will tune 160 through 10 meters continuously and I'd like to avoid the microprocessor interface.

I dunno, if one person understands it and happens to have a source for PLLs, I'll be happy. It's true, though, that I can go to the trash bins down the street, and pick up VCRs with wideband electronics that will carry from DC to 4 MHz, TV sets with great digital tuner stages, really slick sweep amplifier stages that can put out decent power across the whole HF band, and all kinds of nifty stuff. People complain about technology today making homebrewing impossible, but frankly I would have given my eyeteeth for this sort of salvage when I was a kid. --scott -- "C'est un Nagra.

Thanks for the tip, Carl. Geeze, Analog Devices. I should have remembered.
It has been quite a few years since I worked in Materials Engineering and actually had a feel for the current state of the art. Heck, I was only off by a factor of 10 on that clock rate! 10 percent is one thing, but by a decade! :) LOL. Be grateful I didn't suggest wiring a bunch of 12AU7s together in flip flops. Hmmm ... where'd I put that core memory anyways? BTW, those 400 MHz devices are 10 cents per dozen, right? :) I will check out the site, however; again, thanks for the tip. 73 from Rochester, NY Jim AA2QA aka "trailing edge technology" :) "Carl R. Stevenson" wrote in message ... Some of the newer DDS devices (check Analog Devices' website) are clocking at up to 400MHz (maybe more by now, as I haven't looked in a few months). Some provide quadrature outputs. Some provide on-chip phase modulation and/or FSK. There are also techniques using harmonic aliases that will allow a relatively low frequency DDS to effectively produce a higher frequency signal ... Lots of interesting stuff in the data sheets and app notes. 73, Carl - wk3c --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

Some of us have ALWAYS built our own equipment. That's why
some of us became "hams" --- so we could test it out..... Alas, most today are appliance operators. I can't, personally, see any thrill at all in spending 2K for a rig designed and built by strangers, and spending a month reading the manual learning how to use it... Still, there's room in the hobby for all of us. And, in fact, there's a whole lot of us that have more degrees and licenses than can fit on a good sized wall. Enjoy whatever facet of it you choose.... Andy W4OAH |

ISTR that the programming interface for PLL chips is the three wire serial
form, with a static clock. you _COULD_ drive it with three switches, but you'd have to at least debounce them - RS flip-flop from NAND ususally being the simplest way. Might be interesting to derive a driving circuit from el-bug principles! Scott Dorsey wrote in message ...

Seriously, however, there are affordable AMD devices but they appear to be in the 50 MHz to under 200 MHz range. I could do that. Generate a 50-80 Mhz sine wave, then put it into a mixer with a 50 Hz crystal oscillator and turn it into a DC-30 Mhz signal. I think I could even get a brickwall high pass at 30 MHz so the whole thing would be broadband with no tuning. Of course, you'd lose some stability in the process from those extra stages, but probably not enough to be a big issue. Oh, and for 10M FM, of course, I could modulate the local oscillator. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Time to stop whinging, and face the facts...Real Technology has overtaken you all! tox In all honesty, unless go in for VERY low power ( 1Watt), the problem is that you are going to have real problems ensuring that you don't generate unacceptable levels of spurious emissions. To properly test things to the standard required nowadays, with today's high density of electronic equipment in any residential area, you will need test equipment costing much more than a brand new 'off the shelf' set. But it is certainly possible to design your own passive circuits, for instance filters and traps, without this risk being involved. If you are interested in DX, then a commercially designed receiver is going to be much more sensitive and selective, of course. This is due to the fact that a multinational company has the development resources that an individual could only dream of. Obviously, you do gain a lot of respect for designing your own circuits, and you will attract a lot of interest by doing so! So I don't think that 'home brew' will ever die out in it's entirety! DN |
