Hi folks,

I recently acquired a C Line, and have sent the R-4C off for upgrading.
Upon performing an alignment on the T-4XC, and trying it out with my R-4B
receiver, it appears to be transmitting about 700 Hz lower than the display
shows on both the R-4B or the xmtr. itself.  This is regardless of whether
the rcvr. or the xmtr. is controlling the frequency.  It did work very good
with the R-4C, so I don't know if I messed up something during the
alignment, or if the Carrier Oscillator connection to the R-4C locked it in
to where it should be.

I checked the Carrier Oscillator frequency by connecting it to the counter
of my TR7, and it is right on 5645 KHz via C6.  I believe I performed the
alignment okay per the manual, although the Carrier Oscillator, Filter
Match, and Balanced Modulator adjustments were performed while watching the
S meter on my TR7, since the S Meter isn't responsive enough to notice the
change as in plate current as described.  I am having some trouble getting
any canary chirping sound with the R-4B while attempting the transceive
alignment.  I'm getting a steady tone of around 800 or so Hz that rises or
lowers with the adjustment of C-61 in the R-4B.

Any ideas as to what might be happening here?

Thank you in advance for any suggestions to try!
