An idea that I fielded some time ago, but did not pursue because
of a lack of support, was that we should encourage homebrewing, not by a range of disparate kits, but by having a set of standard biscuits, each with a defined input / output interface such that radios from the very simple to the very complex could be assembled from a selection of such biscuits. eg, an RF amplifier, 50 ohm in and out, 12V supply, agc input to give a gain range from unity to 20dB, to be used as RF or IF amplifiers. Now, it is possible that with the onset of SDR, that such an approach would be obselescent, but SDR itself is already notorious for being an off-the-shelf Cheque Book (CB) approach both for the hardware and also the software. |

This is amateur radio; it doesn't need to be state of the art, as long as does the job. but SDR itself is already notorious Where is it notorious? for being an off-the-shelf Cheque Book (CB) approach both for the hardware and also the software. |

But modules are too diverse. Yes, they will have an output, and often an input, but there may be a third input, and this one might need more controls and that one less. Building as modules makes sense, because then it's easier to scrap part of it if it doesn't work, or reuse it in some other project. But buying off the shelf modules, I don't see that happening much. International Crystal in the US used to offer a wide variety of modules over time. Not just the solid state ones in the late sixties and early seventies, which were pretty generic (a crystal oscillator, a mixer, a wideband amplifier, a low power output amplifier), but earlier on, enough modules to build up complete units. But really, they seemed more about building up units as described by the company, and it ended up very costly. It wasn't like trying new things by mixing and matching modules. Or, there was a company in Germany (was it KVG of filter fame, or a separate company, I can't remember) that sold some nice preassembled boards in the early seventies. But those weren't a single stage per board, they were things like an SSB exciter IF strip (or maybe receive too). They were very interesting at the time, but also very expensive by the time they came over to North America. The job of Modules were taken over by ICs in the seventies. And you see the same thing. Either something very exotic that could be used for only one thing, or something very generic, which didn't do that much in itself. Now, it is possible that with the onset of SDR, that such an approach would be obselescent, but SDR itself is already notorious for being an off-the-shelf Cheque Book (CB) approach both for the hardware and also the software. THings called SDRs seem to vary. There are shortwave radios out there that use very flexible ICs, which requires a computer to set up, but I'm not sure how much you can define. There's the Eton/Grundig G8. One could modify it for your own microprocessor and get more steps of selectivity, for instance, but I don't think you can do anything to get SSB on the receiver, it's not about programming the whole thing. SOmething like those DTV dongles seem to be more programmable, I don't know if the A/D conversion is in there or what. But, one now has to learn so much to program them, and be able to make them do other things. I think for most, many SDRs are about letting someone else define things. Michael |

Would you describe gnuradio or Matlab as an "off the shelf" approach ? The schematics for the Ettus range of USRPs and daughterboards are available, anyone so inclined could build their own should they choose rather than purchasing one. See http://files.ettus.com/schematics/ I've published examples of gnuradio flowgraphs before, so wont repeat them, but you can get a DVB dongle for about 6 UKP from ebay, for which gnuradio has drivers for. There are plenty of other examples out on the internet, why not give gnuradio a try ? It really isn't off-the-shelf, and you will have to twiddle bits and pieces (gain levels, squelch values, filter widths etc to get things exactly how you want them) I look forward to comparing your flowgraphs to my own methods 73s Iain |

You can literally write your own radio. It will work with those "DTV" dongles, the FCD dongles, as well as the Ettus range of USRPs when you are ready to "graduate" (they are not cheap), as well as many other hardware devices A Pi 2, a soundcard, a 60k-ish receiver, and gnuradio could easily be used to receive MSF, DCF, WWVB etc. (and the 60kHz receiver is only needed if the wolfson board filters above audio frequencies, I must acquire one to test that, my onboard PC's doesn't so it does LF duties) A HF upverter added to the front end, and you are all set. 73s Iain |

I do like the maths of SDRs etc. but actually using them holds little attraction. The same goes for modes like PSK etc. I've no issue with others enjoying them, they just don't appeal to me. |

Yes, transverters can be a bit of fiddle. In the 70s, I made one to go with my 80 to 10m gear (on 14MHz), to get on 160m. It worked OK, but it was all a bit of a fiddle if I wanted to swap back and forth. I built a europa into an FT101 speaker cabinet ....I had to cut a bit off each end of the circuit board.... build a chassis..... cut a front panel for the europa meter.....stuck in a coax relay instead of the crappy bog standard one...... painted the front panel morris oxford green.....stuck an ft101 fan on the back..........oh yes and white leteraset .....and laquared the front panel...I surprised myself with the result |

I saw talk somwhere about the price of punches. I remember them being as "expensive" forty years ago, but still within range. But apparently now they have gotten really expensive. The best thing was to know someone who had a set. It wasn't uncommon back then to build accessories to match commercial equipment. People would build things to match Heathkit, either buying a third party cabinet (there were some that looked alike) and painting it the right color, or buying a speaker that matched the rig, and using that. Indeed, I remember various projects where people would stuff things into the speaker cabinet, lots of room so long as you didnt' need many controls. Michael |

Michael yes I was deluded about matching equipment in the 70's ...now I hate matching equipment and frown upon hammy mens that must have it all sitting lined up just like the sales brochure.....and I just knew I would never use that punch again......at least with cars you know you will use your torque wrench....torq sockets......impact screwdriver.....spring clamps.....hub remover.... and oil filter removal cup wrench...etc |

I am falling into one trap and that is responding to the tripe that you offer instead of a conversation. There is nothing gratuitous about my remarks. I am calling the shots as I see them without bias. You refuse to even consider that you are as much a part of the problem as the others are. I won't continue to discuss this with you, as I have said my piece. You can either improve your behavior or continue as you have done in the past. So show some restraint and prove me wrong, or continue to blame others for your issues and prove me right. -- Rick |
