Re: [TenTec] MFJ Filter to work on TT540

["Hulett, Russell" <rhulett1@consolidated.net>]

Well, the connections used by the TT245 in the TT540 aren't like the header 
shown in the MFJ info.  The 245 has 7 vector pins spaced about 1/4 inch apart.  
FWIW, I built a clone of the TT245 for my 544.  You could use vector board to 
just wire one up, but had a PCB fabricated for mine.  Works same as the 
original.

BTW, the TT245 isn't in the IF, it is an audio filter.  An outboard filter like 
the NEscaf or MFJ751B would do as well, plugged into the audio output jack.
