The stations are in the correct location on the dial (at least relatively close) My favorite station is at 1300khz and I have that exact. I also used the signal generator to set 600khz. In between and beyond can be off a bit, but not too bad. When setting the 600khz, the signal generator was set up with nothing more than a wire as an antenna and the signal was picked up by the radio via a short wire on the antenna clip. IF was set at exactly 175 khz as required.
The primary of the antenna coil (the part that is on the outside of the form) and the RF amp coil were open. The 38 gauge wire had disintegrated in several locations so I had to rewind them. I understand this is not an uncommon phenomenon on Philco radios. I was as careful as I know how in counting the windings and setting the new wire in the same location as neatly as possible. Is it possible that an error in the winding of these coils could cause the situation? Understand that stations do come in down there, they are just noticeably weaker than on the upper end of the dial.
