Kris -
Yep, I don't think there ever was a TR-4Cw/RIT "manual" as such. They
just took the last TR-4Cw manual, s/n 42500 (with it's two page
'Addendum' covering the 500 Hz filter) and the two additional pages for
the RIT circuitry. This one had a photo of the 'Cw on the cover. There
was NO documentation for the NEW (and different) PTO in the 'RIT model.

I have a late model TR4-CW/RIT (Ser. # 44679) - the original manual
had "TR-4Cw" on the cover, and the manual has the correct photo
showing the three position side band switch (the third position is the
500 Hz CW position), plus the RIT and Noise Blanker buttons. The
manual has two "Supplemental Instructions" (and schematics) on pages
iv to vii before the Introduction. The rest of the manual does not
mention the rit or the cw filter. It is obviously the basic TR-C
manual because the main schematic does not show any of the
supplemental options.

Subject: [Drakelist] TR4 Versions
Very interesting.. I have aTR-4 version with the NB switch and the
socket labeled for 34PNB. The manual copy I have shows a picture on
the cover with the NB switch but the manual does not seem to mention
the switch nor does the schematic include the NB socket...
Are there more versions of the manual/schematic around? I think I
got this copy from DK.Mods or Bama
