* ESSB TRANSMIT CAN USE THE FM FILTER: The wide (FM) crystal filter  
can now be assigned to ESSB transmit as well as FM and AM. This can  
potentially free up a crystal filter slot for customers who were using  
the 6-kHz filter only for AM or ESSB. NOTE: The 6-kHz filter is still  
recommended for high-performance ESSB and AM receive, as it will  
provide significantly better close-in dynamic range than the FM filter.

* TRANSVERTER FREQUENCY ENTRY FIXED:  The previous firmware release  
did not handle direct frequency entry to transverter bands correctly  
(e.g., 144 MHz came out as 180 MHz). This also affected memory recall  
of transverter bands.
