[Elecraft] KX1: A Fourth Undocumented Receive Mode/Frequency Memory for Each Band

[Bruce Prior]

The Elecraft KX1 Transceiver Owner's Manual says: "Three frequency memories 
are available on each band, accessed using the RCL (recall) menu item." (p. 
67)

That understates the memory capabilities of the KX1.  There are actually 
four memories per band, and both receive mode (normal, LSB and USB) and 
frequency are saved in each of the four memories per band.  The fourth 
memory for each band is a temporary one which is saved each time the blue 
BAND button is tapped once.

The documented purpose of tapping BAND once is to display the current 
receive mode and frequency on the low-current LED display.  If the audio 
feedback system is enabled via the CFb menu item or via holding MENU or BAND 
or RIT upon power-up, then the receive mode and frequency to the nearest 
kilohertz are enunciated in audible Morse when the BAND button is
tapped once.

This temporary memory is a most useful operating tool in the KX1 which I use 
frequently.  Having tapped BAND once, whenever I turn the rig off or 
whenever I return to the original band after having switched bands, that 
temporary receive mode and frequency will be available for immediate use.  
Note that if I change bands or turn the rig off without having first 
temporarily saved the receive mode and frequency by tapping the BAND button, 
then that receive mode and frequency will not be saved.  Suppose, for 
example, in a crowded tent the tuning encoder gets jostled.  If I hadn't 
already locked the encoder electronically, I could still return to my 
operating frequency if I had saved it to this temporary memory.
