[Elecraft] Dial setting 60m digital frequencies?

[Ken]

With the new ability to use PSK31 on the 60m channels, I am uncertain about how to get on the proper frequency.   FCC only allows operation on precisely the center of the channel (e.g. 5405.0).  

As best as I can tell, for 1500 Hz audio, the K3 should be set for the CW frequency +0.625 kHz in reverse Data mode (or the SSB channel frequency +2.125.)   Channel 5 (5405.0) would require setting the K3 dial to 5405.625 with the PSK signal at 1500 Hz.  Channel 2 (5348 center frequency) requires setting the K3 dial to 5348.625 Data Rev.   

Can anyone confirm my calculations?

Tnx,
