WebFor a set with a crystal filter, turn the filter on and set to its narrowest position. Inject a CW signal and adjust freq to find the crystal center. Set the crystal filter to widest, or disable it. Tune all IFTs for max on the VTVM. Keep the sig gen level low, just enough to bring the meter reading above the level with no carrier present. http://www.thebakeliteradio.com/page102/page110/page110.html
