 Standard MSK144 message frames are 72 ms long, compared to 117 ms for
 JTMSK.  The MSK144 waveform allows coherent demodulation, allowing up
 to 3 dB better sensitivity.  After QSO partners have exchanged
-callsigns, MSK144 user can use even shorter messages, only 20 ms long.
-As in all the fast modes in WSJT-X, the 20 ms or 72 ms messages are
+callsigns, MSK144 can use even shorter messages, only 20 ms long.  As
+in all the fast modes in WSJT-X, the 20 ms or 72 ms messages are
 repeated without gaps for the duration of a transmission cycle.  For
 most purposes we recommend a T/R cycle duration of 15 s, but 5 s and
 10 s sequences are also supported.
 
-MSK144 short ("Sh") messages are intended primarily for 144 MHz, where
-most pings are short.  These messages do not contain full callsigns;
-instead, they contain a hash of the entire transmitted message along
-with a report.  They are not encrypted -- the report is sent in the
-clear along with the hash.  Short messages are fully decodable only by
-the station to whom they are addressed, as part of an ongoing QSO,
-because only then will the received hash match that calculated using
-the known strings for "My Call" and "DX Call" and the received report,
-RRR, or 73.  If you are monitoring someone else's QSO, you will not be
-able to decode its Sh messages.

 An MSK144 signal occupies the full bandwidth of a typical SSB
 transmitter, so transmissions are always centered at an offset of
 1500Hz.  For best results, selectable/adjustable Rx and Tx filters
 should be set to provide the flattest possible response over at least
 300 - 2700 Hz.  The maximum permissible frequency offset between you
-and your QSO partner is ± 200 Hz, and less is better.
