This release includes the new #RCF (relative center frequency) command which
was recently added to the P3.  The replay buffer has been removed and in its
place, a new 'scratchpad memory.'  Please refer to the release notes below.

questions, etc.  My email address is pauls at you know where dot com. 


MCU 1.42 / 03/22/2016

* Adds: keyboard macros can now be executed even when the Text Display is
turned off. 

* Adds: #RCF command: “Relative Center Frequency” applies an offset to the
center frequency based on the passed argument.  Usage: #RCFsnnnnnn;  Where:
‘s’ is the sign + or -, nnnnnn is the offset in Hz.  For example, if the PX3
is set to a 30 kHz span and you would like to position the cursor on the
left edge: #RCF+015000;   Using #RCF without any arguments returns the
difference in Hz between the center frequency and the vfo frequency. 

* Fixes/Adds: Removed replay buffer and its controls and in its place added
a “scratchpad”  to hold temporary text such as call signs, names, etc.  Text
may be added to the scratch pad by first pressing the Insert key.  The
scratchpad is cleared each time it is opened.  To move the scratchpad
contents to the Tx buffer, press Ctrl-Insert.  Pressing Ctrl-H when the
scratchpad is open, displays a help screen.  To exit the scratchpad, press
Esc, Enter or Insert.  You may also press a text macro assigned key which
will execute after exiting the scratchpad.  To embed the scratchpad contents
in a text message, use \s . The scratchpad holds one line of text.  It is
erased after each power cycle. 

* Fixes: USB/LSB passband inversion when using transverters. 

* Fixes: an issue when using the ‘|’ command (IM) with text message strings
shorter than 10 characters.  The IM character is now correctly interpreted
which should solve the problem of truncated strings. 

* Fixes: Keyboard help screen being overwritten by spectrum trace and grid. 

* Fixes: Full Tx keyboard buffer overflow issue in which buffer could not be
sent with Enter.

Very 73,
