![]() I'm just brushing you off. I wrote to let you know of another avenue to do the job you wish to do where someone else has invested a tremendous amount of professional work in both the hardware and software. It will be available on the Internet in a week or so. (Several of us have enjoyed the end product as a Beta test group for something over a year.) I don't have any time or interest in participating in a sincere dialog. Regards W4ZCB Hi Harold, I well recall Paul's wattmeter- well ( or even way) beyond what others had done- the engineering and documentation was superb. Looking forward to his work on the VNR. I am not far from you- near Cashiers on Lake Glenville. Dale W4OP |

done- the engineering and documentation was superb. Looking forward to his work on the VNR. I am not far from you- near Cashiers on Lake Glenville. Dale W4OP Hi Dale, I had no idea that you were that close. Been to Glenville many times. Why don't you come over on the first Wednesday of any month for our QCWA lunch. We have a very active group and actually have two meetings a month, but the first one always has an interesting program. If it poses a problem doing it in one day, We have a great guest apartment and I'd put you up for a Tuesday night sort of thing. You can even play with my STAR. A little DSP transceiver that Peter Rhodes developed. 160-10 with superb characteristics. There are 9 of those finished now, with another half dozen in various stages of completion just in the Beta group. I have no idea how many more are being built as the project continues to evolve in Radio Communications. If you liked Paul's wattmeter, you'll be blown away with what he's done with the VNA. Documentation itself is in 3 parts and looks like a doctoral dissertation. Both Paul and Bill Carver were here last month (Wish I had known you were this close! We met Alan Victor and Jim Scarlett and his son at Shelby for lunch) and brought their VNA's along for a round robin test. Under 1 percent variations on the Q of a test crystal between the units. He's added software to make it perform a half dozen other tasks, Transmission, Reflection, Group delay and some real time stuff. I've junked my dual crystal oscillators in the quad shield for Ip3 tests, the VNA does it on ANY frequency. A real "Lab in a Box". I think I've run the antenna characteristics on everybody's antennas within a 10 mile radius. Regards W4ZCB |

Hi, all concerned:
Everybody wants to do it in software ;o) Telescoping brass tubes from hobby sources, or telescoping aluminum tubes from eg Texas Towers, can be used to build physical line-stretchers. Put the movable parts in a trough say of copper or aluminum gutter for unbalanced apps. Plan the device parts carefully, and near-50-ohm surge impedance can be had by purists and others. 73, Dave, N3HE "John Miles" wrote in message ... In article , says... Do it the way you want to. Harold, I'm puzzled by your reply. Does it mean that you agree, or that you disagree, or that you're just brushing me off? If it's the latter, I can accept that too...I'm just looking for a sincere dialog about an idea. Who knows what he meant by that, but the idea of using a "line stretching" hack to resolve the phase ambiguity sounds like a great one SNIP |
