Each tuning condenser will be about the same position for each station on the dial. Sometimes there is some deviation from this, but in general this holds true.
Most of the tuning is fairly broad, but it helps a lot to keep notes on reception each time you use the radio, and tuning will become intuitive pretty quick. Usually tune with the "Antenna" or "RF" stage first, keeping the other two tuning dials close, then fine tune with the other two dials.
If there is one station bleeding over a portion of the band, add a "wave trap", and tune the trap to that station. A wave trap is simply a coil and tuning condenser (as you would have for a crystal radio) attached between the antenna and ground- tune the radio to point just off the main tuning for that station, and tune it until the station is either eliminated, or minimized.
:Having difficulty converting this radio to AC. Have DC power supply for filaments, power supply for B+ Any signal received is very weak lots of oscillations especially when varying the vc. Since the three tuners are not ganged, how do you tune them so they are in resonance. Are they broad ? Thanks John
Thanks John for the info The long wire ant did the trick. One other question. The output of the 301 tube i beleive is hi impedance. I have an old peerless spke i am going to use. Can i couple this skeaker to the plate of the 301? This puts B+ on the speaker John
::Hi,
::Have as long of an antenna as you can accomodate, and have a good connection for the ground of the radio to a cold water pipe, or well pipe, or ground stake outside.
