N.B. I have seen at least 4 different pdf files on the web under the name MFJ-949 which are totally NOT MFJ-949's. The part numbers are different and the schematics are not exactly the same. One of them was the 300M with single meter and no balun, although it was clearly labelled MFJ-949.pdf. I think the early 948 was the single meter version but there seems to be absolutely no info on the 948 that includes a schematic diagram, so I assume it is basically the same as the 949, possibly without the dummy load..
If anyone can supply a schematic of the 948 I would be pleased to add it to this list.
