Finally...a place to use that old T-21/ARC-5, BC-458, or 5.3-7Mc ATA!

There's interesting detail about carrier versus center frequency in the 
*new*
Section 97.303:

---QUOTE---
(h) 60 m band: (1) In the 5330.5-5406.4 kHz band (60 m band), amateur 
stations
may transmit only on the five center frequencies specified in the table 
below.
In order to meet this requirement, control operators of stations 
transmitting
phone, data, and RTTY emissions (emission designators 2K80J3E, 2K80J2D, and
60H0J2B, respectively) may set the carrier frequency 1.5 kHz below the 
center
frequency as specified in the table below. For CW emissions (emission 
designator
150HA1A), the carrier frequency is set to the center frequency...

  60M BAND FREQUENCIES (KHZ)
     Carrier   Center
     5330.5    5332.0
     5346.5    5348.0
     5357.0    5358.5
     5371.5    5373.0
     5403.5    5405.0
---END QUOTE---

Note the *requirement*:  "For CW emissions ... the carrier frequency is 
set to
the center frequency."

For example, switching from USB Phone on 5357.0 kHz to CW on the *same* 
channel,
the transmitter must transmit on 5358.5 kHz.  That will produce a 1500 
Hz tone
in a USB receiver set to 5357.0 kHz.  It appears that now a transceiver 
will
need to shift not only the transmitter's carrier from 5357.0 to 5358.5 kHz,
but also receiver's effective frequency up by the amount needed to 
produce the
desired sidetone when tuned to a 5358.5 kHz CW signal.  The wording in 
the new
rule seems to introduce an unfortunate and valueless complexity for CW 
operation.
