Ok, so I went and bought one because I need one for some TXSG HF stuff and decided to go ahead and get the biggest and best one I could find locally. What a P.O.S the thing is! It came in what I assume was a factory box, but inside the box: The thing was rolling around loose inside the box wit

The BC-610 is neutralized on one band and then it is set for all bands. Coverage from 2 - 18 mc is setup on 40 meters then left alone. However when making the manual mods for 160 meter operation the neutralizing has to be done for that band only, and it is not valid for any other band. When going

This is the screen-choke self modulation technique. Screen current is affected by the modulated plate voltage, and the screen choke lets the screen vary above and below the screen suply voltage according to screen current. If the choke is large enough (you need 10 to 20 henries), the screen can f
