If you are using Window Defender Antivirus (Windows 10), update it to its latest malware definition in https://www.microsoft.com/en-us/wdsi/definitions before installing or upgrading to Commander 15.1.6 This release - only displays a warning message when controlling a Kenwood or Yeasu transceiver that requires RTS set to 'On' when directly connected and no data has been received from the transceiver after 5 seconds if the Primary CAT Port's RTS selector is set to 'Off' (tnx to Saad N5FF, Joe W4TV, and Bill G4WJS)) - correctly reports Network Service UDP address and port errors (tnx to Jon K6OJ) - when selecting an Icom transceiver that only supports a single data sub-mode, automatically selects that data mode (tnx to Steve NS4P) - interoperates with Steve N2IC's "Waterfall Bandmap" application; please see note 1 below (tnx to Steve N2IC and Dick K6PBF) - when an Elecraft K3, K3S, KX3, or KX2 is first selected, directs it to report its firmware versions and records them to the errorlog.txt file if error logging is enabled (tnx to Mike K6MKF) - supports the Icom IC-275, IC-475, and IC-575 (tnx to Larry W1SIM) - enables tracking of the Primary transceiver's frequency and mode on a TenTec Argonaut V, Argonaut VI, Eagle, Jupiter, or Omni VII connected to the Secondary CAT port (tnx to Howard K7JNX) - updates the Configuration.htm, NetworkService.htm, and TXMeter.htm documentation files Notes 1. Step-by-step instructions for enabling interoperation with the Waterfall Bandmap application are available via https://www.dxlabsuite.com/dxlabwiki/WaterfallBandmap - this is a work-in-progress, not a completed capability; tighter interoperation is planned - the Waterfall Bandmap application can only display the most recent active callsign on a frequency - known defect: the Waterfall Bandmap application sometimes erroneously displays two or more callsigns on top of each other, making the callsigns unreadable 2. In this version, the Secondary CAT Port's "CAT Protocol" selector can be set to "FlexRadio PGXL", but this is not yet working correctly with a FlexRadio PGXL amplifier. 3.
