MFJ 400 Econo Keyer

[W5RRP]

Does anyne have the instructions for the MFJ 400 Econo Keyer?  Do you have to make any internal changes for the output (Direct/Grid Block)?

Mighty Fine has almost all their manuals on line at their main site.

I looked on MFJ's site and could not find a listing for your keyer. The only one that came close I think is the econo keyer two. Look on page two of the manual, and it talks about the keying. Look in your radio manual and see what it requires. Copy and paste the following link and see if that what you are looking for  http://www.mfjenterprises.com/man/pdf/MFJ-401D.pdf

MFJ does not list a manual for the 400, and the 400 is not related to the 401 by anything other than the fact that it is a keyer made by MFJ.  I have requested help from MFJ, and will see what I hear from them after the weekend.
