Strongly agree, Barry. But second is smooth response, low distortion. Both reduce fatigue. WIDE response is fine, but less important. 73, Jim K9YC _______________________________________________ CQ-C

Something to think about. I've heard that Kindle isn't a great way to read/study technical books, because it's not easy to jump around to look at something in the book referenced by pages you're curr

Why not just copy what they send during the contest? Contests are INTENDED to be a measure of an operator's ability to copy what the other station sends DURING THE CONTEST. 73, Jim K9YC _____________

Properly done, they can kill second harmonics of the power amp. That's a big deal when you're operating SO2R CW on 80, 40, and 20. What's the advantage compared to LPF or BPFs? Most of these filters

Your logic is exactly backwards, Jukka, and it applies ONLY to optimizing the relationship between the stub and the power amp. When the output circuit element is a capacitor, the stub should be 1/4 w

qrz.com shows that all LIVE in the golden eastern half of NA. So VERY unlikely that anything will happen to make these contests interesting for stations contesting outside the Atlantic basin. 73, Jim

In case you really split the hairs, there is a connection between the two; placement and length; but it is weak. This is false. In case you really want to experiment, make the stub a little long. -if

Top quality RG11 works well for stubs. Top quality means a low resistance of both center conductor and shield, and good quality control. Belden 8213 is an example of a very good RG11. 73, Jim K9YC __
