Hi, Scott, In fact, I made a number of similar modifications to one of the Astron SS- family (like Paul's) after I got one about six years ago. I was not pleased with the RFI before the mods but afte
Hi, Mark, Do what you have to do, but I just took another look at the Omni Six product review (in January 1993 QST) and the TS-2000 product review (in July 2001 QST). I like the oscilloscope screen s
MRF 458s have been going extinct for several years now. It gets harder and harder-- and more and more expensive-- to find them. You should be able to substitute MRF 454's with little change in perfor
Unfortunately, all switching power supplies generate RFI. That's why the League publishes those measurements. The only thing you can do is try and minimize the noise coming out of the switching power
Ah, Windows. There was an recent editorial in one of the computer magazines saying how, after all these years, Windows is still not any easier to use, really; still not where it needs to be in terms
http://lists.contesting.com/_cq-contest/2002-June/048011.html Hi, Rich, Click on the link above to see a post that was made just this week on the CQ-Contest reflector by big-time contester Dave, K6LL
I am delighted that several folks have indicated their decision *not* to purchase a new Orion, a decision based predominantly on the display and other cosmetic issues. I hope that many hams, especial
I don't know about the headphones being the culprit; wouldn't it be the listening levels (volume) really doing the damage? It reminded me of a post from last year: http://lists.contesting.com/_tentec
In the last few years I have become convinced that the two-tone 3rd order dynamic range numbers in ARRL reviews measured with a 20 kHz tone spacing are absolutely irrelevant in demanding amateur radi
You know, Duane brings up something I have always wondered about. An example: When a manufacturer says that their radio has 100 dB of dynamic range, is that a guaranteed figure? Or is it an average n
Bill, I guess you're right. I guess we can read between the lines of a review to get the real scoop. And as you say, this is where a picture is worth a thousand... you know. Pictures as in photograph
Stuart, I think I can say this without offending you, but this must be the most complicated thing ever invented, or else my brain is finally starting to show signs of carelessness in my younger years
Right, Paul. This is another way of approaching the question I posted last week (about which no one has really had anything to say). If the same final amplifier design can vary by that much... it thr
Hey, Stuart, don't forget to post this to the rec.radio.amateur.antenna newsgroup. WARNING: You're going to get hammered, but you may also get some interesting reactions from the technically astute t
As a QRP aficionado, I am inclined to agree that 1.7 dB isn't a big enough difference to worry about, but I suppose there could be reasons why it would be important to someone. Perhaps a person has 1
Hi, Mike, The suggestions so far put forth will all work, but you will very quickly hit a limit on the receive bandwidth on the Omni VI which is caused by the DSP codec always being in the receive p
Yes, that's right, Barry. You pick off direct from the product detector and you lose all of the DSP functionality if you go into the volume control, which is presumably what your mod does. I haven't
I posted a reply about measuring "microchirp" yesterday but it never made it to the list. Here's my second try: -- In fact, you can. You need an instrument that can capture a signal without missing a
Paul-- Man, you are absolutely right. I really just wanted people to know that you can measure just about anything given the right test equipment. I don't really appreciate it enough, but one of the
