The "RIT" PTO first appeared in the TR-4CwRIT. This version ONLY used
the former RTTY terminal on the side just behind the gearbox for an
included RIT circuit. It is the same PTO as the 7 Series. In fact,
the only schematic for the CwRIT PTO is in the RV-7 manual.

Isn't the 4 line PTO different than the 7 line PTO in that there is no
circuitry for RIT inside PTO in 4 line,later incorporated in 7 line?
5 & 7 line PTO's the same,except for no dial plates on the 5 line,and
reverse tuning due to Xtal mixing scheme on TR5

Hello to the group.
Have a TR7 ...mid range serial number.
Without tearing a bunch of stuff apart.....
also have a TR5 and a TR4c, .... the question ...is the pto action on
the 7 stiffer than the other two. The 5 is like silk and the 4c
feels just a tad stiffer than the 5.
Per the archives ..the 7 pto is the same as the 4c, is the 5 the same?
Next was a recent write up on an R7 that said there was a mechanical
lever to release the gear on the pto to enable a mechanical
alignment on the dial. Is that the same on the TR7?
