Right on, Tom. Nearly repeating what Tom posted, beverages, pennants, et al are all about **NOT** HEARING WHAT YOU **DON'T** WANT TO HEAR. That means you need to know WHERE what you DON'T want to hea

In EZNEC 3.0, on your chosen antenna, set the plot type to 3D. Then select FF Plot. At the bottom of the main EZNEC window (not the plot window) it will give the average gain. Use real ground and spe

Getting significant common mode suppression on 160 meters with split blocks or "beads" for RG8 size coax is rather expensive unless you just happen to have a private stock. Try 76" of RG-400/U and a

If you get on the Elecraft reflector archives, and search on "clicks" you will see quite a thread on it. I have a K2, and I have measured the clicks on mine. A crude summary, K2 does have clicks, but

Hmm, what would have been the cause of the blackened, pitted contacts on the antenna relay on my AL1200, which I had to replace, before I caught on to the delay settings in my MP. I would definitely

The problem with a SteppIR would be that the tower tuning changes with the band and frequency the SteppIR is set to. At the very least the SteppIR would need to always be set for a certain frequency

If you use an MP, you can use the menu to set a running fixed delay between key down and power out on CW. This causes the entire cw waveform to be continuously delayed by up to 30 ms. This is like a
