Steve -
What did you do to the PTO in R-4B #2? I thought they were both jumpy?
I would use just about any small coax you have for the injection. It's not long enough to matter
what impedance or loss (within reason!) it is.
The headphone jack on the R-4A was in that location, and the panel still has the locator mark in the
"B" location, and of course the main chassis has the cut-out needed. Drake probably had enough
'complaints' about the front panel location interfering with access to the RF GAIN and the SSB/CW
switch. I didn't complain, but the PHONE plug body sticking out there made it very difficult to
switch the SSB/CW switch.
So now we have to deal with the silly little flat plugs!

Now I'm home (and listening to R-4B #2, which is going to need to be re-capped but is otherwise
working in a sterling manner) and checked out the info on the PBT assembly. It sounds pretty
simple once the cover is removed.
I'm now at the point with R-4B #1 where I feel that I owe it to the rig to put it back - more or
less - to the way Bob Drake intended it to be. That means I'll need to re-route a new Injection
cable inside the rig, as the PO shortened it when he moved it over to the SPARE location (WHY he
did this, I will never know, and it's my understanding that he's an SK). The audio mods I'll
probably leave in, as the rig sounds nice and rich, but that variable AGC delay is seriously
messing up the ability to control RF gain. I think I'll put a headphone jack where that extra
goofy knob is as I have seen more than a couple of B's that have had this change (in all honesty,
moving the headphone jack to the side wasn't a great move...)
Question here is this: what can I use for the internal cable in the R-4B to go from the pre-mixer
to the INJ jack? I will have to replace this since the PO shortened it :-(

ROTHFLMAO!!! Made my day reading your softly worded post, Garey! Had to
clean up some coffee that squirted out, though. RTFCD and derivatives;
i.e., RTFIM, RTFD, etc., are most fun play words. :-))))
