<DIV><SPAN class=000104623-11012013><FONT size=2 face=Arial>I measured TX
frequncy of PowerSDR.</FONT></SPAN></DIV>
<DIV><SPAN class=000104623-11012013><FONT size=2 face=Arial>Frequency set to
3.650 000 in CW on the display.</FONT></SPAN></DIV>
<DIV><SPAN class=000104623-11012013><FONT size=2 face=Arial>However the
measured frequency in transmission is 3.559 9715.</FONT></SPAN></DIV>
<DIV><SPAN class=000104623-11012013><FONT size=2 face=Arial>About 28 Hz down.
Receiving is quite normal, e.g. in the reception of strong AM broadcasting
station by tuning in the excat frequncy display, LSB or USB is the same sound.
If there is a 28Hz difference we can easily identify the frequency
difference listening music in LSB or USB.</FONT></SPAN></DIV>

<DIV><SPAN class=000104623-11012013><FONT size=2 face=Arial>The above is the
result of newlly installed PowerSDR V2.2 (11/24/12). The board is Hermes V2.1.
External 10MHz OCXO is used, its accuracy is confimred after the above
measurement.</FONT></SPAN></DIV>

<DIV><SPAN class=000104623-11012013><FONT size=2 face=Arial>The infomration
about the above is very much appreciated. So far I've transmitted in the wrong
frequncy.</FONT></SPAN></DIV>
