I did remove the 1k swamping resistor from the primary of the 1st 455kHz I.F. transformer. Gain came up quite a bit, so the radio sounds more like a 651S-1 or a 75A-4. Considering you're not getting any overloading on any band, why do you suppose they put it there in the first place? I can only think of reducing primary Q, which doesn't seem terribly worthwhile. |
