I think you should consider expressing the frequency in question in 
terms of it's USB equivalent.  

    * LSB operation is almost unheard of on 10 meters (at least in North
      America).

    * All radios default to USB mode on this band. Many require multiple
      button pushes or menu levels to switch to the non-default LSB.

    * Nearly all  commercial, marine, and military-surplus SSB radios
      (that hams sometimes acquire second hand) ONLY operate on USB.


Or better yet, specify the actual RF mark/space freqs so that users with 
devices that have odd tone pairs such as the TigerTronics TigerTrack 
(1100/1300 Hz audio tones),   or fully variable tones (such as the MixW 
soft modem on packet),   can calculate what RF freq [USB or LSB] to use.  

Note further that the paid-for "Pro" version of AGWpe can use standard 
KAM tones (1600/1800).
