+the likely propagation to <prefix></CODE>
+<P>
+<P>This command allow you to estimate the likelihood of you contacting
+a station with the prefix you have specified. The output assumes a modest
+power of 20dBW and receiver sensitivity of -123dBm (about 0.15muV/10dB SINAD)
+<P>The result predicts the most likely operating frequencies and signal
+levels for high frequency (shortwave) radio propagation paths on
+specified days of the year and hours of the day. It is most useful for
+paths between 250 km and 6000 km, but can be used with reduced accuracy
+for paths shorter or longer than this.
+<P>The command uses a routine MINIMUF 3.5 developed by the U.S. Navy and
+used to predict the MUF given the predicted flux, day of the year,
+hour of the day and geographic coordinates of the transmitter and
+receiver. This routine is reasonably accurate for the purposes here,
+with a claimed RMS error of 3.8 MHz, but much smaller and less complex
+than the programs used by major shortwave broadcasting organizations,
+such as the Voice of America.
+<P>The command will display some header information detailing its
+assumptions, together with the locations, latitude and longitudes and
+bearings. It will then show UTC (UT), local time at the other end
+(LT), calculate the MUFs, Sun zenith angle at the midpoint of the path
+(Zen) and the likely signal strengths. Then for each frequency for which
+the system thinks there is a likelihood of a circuit it prints a value.
+<P>The value is currently a likely S meter reading based on the conventional
+6dB / S point scale. If the value has a '+' appended it means that it is
+1/2 an S point stronger. If the value is preceeded by an 'm' it means that
+there is likely to be much fading and by an 's' that the signal is likely
+to be noisy.
+<P>By default SHOW/MUF will show the next two hours worth of data. You
+can specify anything up to 24 hours worth of data by appending the no of
