Not necessarily. Many of the worst offending rigs have adjustable rise time. The fastest settings produce the worst clicks. Also, we need to start considering rig cleanliness when making buying decis

Actually there are. Depends on the design of the radio and also how you set the rise time. See k9yc.com/TXNoise.pdf 73, Jim K9YC _______________________________________________ CQ-Contest mailing lis
http://cqww.com/blog/ Bravo on the DQs and the warnings. BUT -- it's awfully hard to believe that only three stations had "wide signals" in this contest! 73, Jim K9YC ________________________________
Almost all of my emails coming in from this reflector are ending up in my spam mailbox of my Yahoo account. Is there a way to fix this? Any help would be greatly appreciated. I have a yahoo account,
CW - width greater than 500Hz at 40db down SSB - width greater than 6kHz at 40db down Having studied this matter for a while, and having done some measurements of my own, I'll throw these thoughts on
Say you have a AM Broadcast station, 740 Khz, At night it drops down to a measly 6 watts, Could you possibly be able to make a filter good enough to be able to while that is still transmitting it's 6
And not ALL Americans, only for those around the Atlantic Ocean. And they ARE the ones who write the rules, not only for ARRL contests, but also for most CQ contests. 73, Jim K9YC ___________________

I'm not disputing your positive experience, but exactly the opposite for the above statement, Gerry. Business/industrial falls under Part 15 Class A, which allows the emission of roughly 20 dB more R

Hi Tony, I see your problem. :) The radios I suggested, the K3 and the TS590S, tested very clean for CW bandwidth. No radio tested beats the K3, and the TS590S was second best. k9yc.com/TXNoise.pdf c
Yes, LOTS of fun, especially during the summer months when E-skip is at its peak. Going from memory, I think you and I have worked on 6M. I'm running a K3/P3/KPA500, and work CW, SSB, JT65, JT9, FSK4
Keep at it. I've gone through the process twice, and it took a while to win. :) Consider a 2x1, which also works well for contesting, and can be a big advantage in WPX. I am considering changing my s

I disagree. Herb's observations have a quite solid engineering basis, and he carefully laid them out. By contrast, the posts attempting to explain them away were nothing more than pseudo-science and
Yep. I've done it, with results similar to what Herb reports. You learn who has worked on their RX systems and who has not. 73, Jim K9YC _______________________________________________ CQ-Contest mai
