----- start of message ----- "Noisy DSP experiences". Forum: Articles Subject: An Interesting CQ WPX CW Experience The "noisy DSP" phenomena is well known. Rob Sherwood has also identified this problem and has written about it. I have the following radios K3 K2 Flex5000 IC7700 Perseus ALL the above radios except the K2suffer from the noisy front end problem when mild QRN is around. It sounds like these radios have a reverb unit on the receiver which multiplies static and pulse noise. Elecraft claims to have a cure for this problem, however I still find the receiver noisy. The K2 I prefer over the K3 on CW when there is QRN around. The filters on the K2 sound better on CW when there is QRN about. It amazes me every time that I turn on any of my old old analog radios like the TS830S or the FT1000D and do a comparison. The QRN all of a sudden becomes tolerable and not so nerve wrecking. The TS830S is still my favorite low band radio for picking weak signals out of QRN on 160 and 80 meters. This is especially so when there is a lot static and QRN around. Its unfortunate that there is no current model analog transceiver manufactured that has fantastic receiver dynamic range numbers like the Elecraft K3. The only option available is to build your own like the PA3AKE H-mode mixer high performance receiver. http://www.xs4all.nl/~martein/pa3ake/hmode/ ----- end of message ----- You can see this forum message in full at: http://eham.net/forums/Articles/201100 This email was sent to you from Dick Van Zandt (K9OM) through a notification system on eHam.net. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
