This release - when controlling a Flex Signature radio, displays callsigns on SmartSDR without having to first enable the Bandspread window (tnxt to Ronnie W4RJF, Kent N6WT, and David NX6D) - when controlling a Flex Signature radio, correctly displays callsigns on SmartSDR when running in a locale that doesn't use the period character as a decimal separator (tnx to Andy UA3AB) - when controlling a Flex Signature radio displays the correct radio number in the "Commander Flex Signature Selection" window (tnx to Richard, KC8RP) - when controlling a Flex Signature radio with the display of callsigns on the panadapter enabled, updates the age and "spotted from" information that appears in explanatory popups every minute (tnx to Andy UA3AB) - when controlling a Flex Signature radio with the display of callsigns on the panadapter enabled, responds to a click of a callsign on a panadaptor by setting the radio to the correct frequency and mode and, if the callsign is reported to be operating split, sets VFO B to the last reported QSX and enables split (tnx to Andy UA3AB) - when switching transceivers, closes the Flex Signature TCP and UDP ports - when controlling a Flex SDR-1000, SDR-1500, SDR-3000, or SDR-5000 and directed to change modes by another application, interprets DATA-L to be RTTY[DIGL], and interprets DATA-U to be RTTYR[DIGU] (tnx to Jamie W2QO) - when controlling a Flex SDR-1000, SDR-1500, SDR-3000, or SDR-5000 and directed to change modes by another application, interprets PKT to be RTTY[DIGL], and interprets PKT-R to be RTTYR[DIGU] (tnx to Geoff G4XMJ) - when controlling a Flex SDR-1000, SDR-1500, SDR-3000, or SDR-5000, replaces the RTTY and RTTY-R options in the Main window's Mode panel with DIGL and DIGU (tnx to Geoff G4XMJ) - when started with no Radio Model selected, hides irrelevant options in the Radio panel on the Configuration window's General tab, and informs the user - doesn't generate an errorlog.txt file entry on receiving an notice of an active DX station with no callsign  - when controlling an Icom transceiver with its "CI-V transceive" option enabled, does not consider unrequested frequency and mode reports received to be a response to a previously issued command (tnx to Björn SM7IUN) - when controlling an Icom transceiver with Spectrum capabilities and its "Verify CI-V command acceptance" option enabled, doesn't wait for an ACK/NAK response from the "update band edges" or "send edge #" commands, because the transceiver may not send them if "CI-V transceive" is enabled (tnx to Björn SM7IUN) - changes the "Secondary CAT Port" panel's "Update every second" option to "Update every 200 ms" (tnx to Miro SP5GNI) - updates the Configuration.htm documentation file Notes: 1. See the new article "Smoother Frequency Tracking with Icom Transceivers" in 2. The option to display callsigns on a Flex Signature radio's panadaptor is only provided if you are running SmartSDR version 2.3.7 or later 3. Update your firewall and anti-malware applications to consider this new version of Commander to be "safe" 4. If this upgrade doesn't work correctly, see the "After an Upgrade" section of 5.
