   New Firmware fw. version 70058/0001, accumulated improvements since previous stable release. What is new:

   1. Narrow CW filters for bandwidth : 25Hz, 50Hz, 100Hz have been implemented.
   2. Broadcast FM RDS decoder implmented, Now you can see RDS information (PI and servi​ce name) printed on the screen.
   3. RDS bit 'ASCII G' stream also is sent over telnet protocol and can be forwarded directly to 'RDS Spy' utility for further data processing (groups analyze etc.).
   4. New frequency tuning mode added that can be convenient for use LAn-IQ SDR as panadapter or use SDR for QO100 listening.

   In this mode the Central (NCO) frequency is locked and SDR can be tuned to any frequency inside RX bandwidth, without changing Central frequency. The new tune mode called : Settings, -> Misc. -> NCO lock/Shift tune or ​Mod. -> Ext. -> Shift (NCO) key

   5. Added ability to lock frequency on QO-100 BPSK beacon (Mode.->Ext.. -> S.Lock). All QO100 related operations are located in the same menu.
   6. S-meter now slower and has same delay for every sample rate
   7. Some changes in cw decoder algorithm.
   8. SNR measurement has been added to service. For precision SNR measurement (excluding WFM mode) - it is recommended to use IF or BB/IF screens.

   SDR measures SNR in RX channel bandwidth.

   9. Significant changes in spectrum screens procedures and management.
