FT817 speech processor - English translation

Dave G3YMC kindly did an approximate translation of the German instructions for the Funk Amateur speech processor that I built at the weekend. This may be of use to others building this kit. Dave says this is not a precise translation and does not want to be held responsible if he has made any mistakes!

Incidentally on a local SSB contact with G3KKD this evening I switched from "processor out" to "processor in" and Ian said it nearly blew his head off, so it works, HI.

  2. Hi Roger,

    Here is an article in english of the speech processor, but the version with only one RJ-45. Anyway I think its the same circuit, built around SSM2165 chip:

  3. Roger, thanks for the translation. I found another one but it was indeed the one with a single RJ-45 - and the one I found was indeed different. The two IC's in it were SMD and all the other parts were through hole.
    How did you adjust the compression ratio? 73
