Jerry, Does cooling the D/A and A/D circuits help with the noise ? I work all the time with special applications of Thermoelectric coolers and could very easily cool the whole radio to VERY cold if I
I used to like the reminders. But, that isn't important. What is important is to relax, enjoy the hobby, and be glad that people work so hard to create a nice net. 73 de Gary, AA2IZ stop am I
Yeah... I got one also. Fortunately Norton found it and took care of it. I was just mailed a virus, I'm sure inadvertantly, by someone on the list, in an attachment. Just a heads up. Andy W1AWB _____
Many thanks to all those who responded to my question about a cold front end. Looks like it would not be terribly helpful at HF. So, I guess I will turn my attention to active cooling of the heatsink
Good idea. There is also a brute force one written up in the Handbook for years. I've built them and they are excellent.... provided of course that the AC line is the path for the noise. Don't overlo
Ed, Not the one in the handbook ? 73 de Gary, AA2IZ filter. Radio Shack catalog 15-1111 may help. membership dues, individual contributions and the sale of publications and advertising. For more info
Excellent Points. I'm sure no one intended offense. The subject IS very interesting. I think we have all come to accept that fact that much commercially available software is routinely released with
Well... assuming of course, that the measurement itself contains no error. I have not sat down and done the actual analysis, but I wonder just how accurate these measurements actually are in fact. 73
And ... Good for you, Jim !! I'm very impressed by the calm, even-handed way in which you have handled this important discussion. regards, Gary, AA2IZ -- Original Message -- From: "Jim Reid" <jimr.re
I don't think that the impedance of the headphones is really the significant issue. I think you are getting RF into them. I still have had great success with ferrites, and suggest again trying them.
