UNITS NOW SHIP WITH 1.3 FIRMWARE INSTALLED TO SUPPORT ALLSTARLINK NODE<\/b><\/p>\n
The latest version (V2.2) of this multi-port \u2018universal\u2019 radio controller is a simple device that sits between your computer and transceiver.<\/p>\n
The unit provides the following functions:<\/p>\n
1) USB-C sound card to convert the receive\/transmit audio from the transceiver to USB, capable up to 48,000 samples per second.<\/p>\n
2) Full PTT control to allow automatic receive & transmit using either serial port settings (DTR & CTS) or the CM108 standard supported by popular software (including DireWolf). PTT switching is by a hardware relay for maximum versatility and reliability.<\/p>\n
3) CAT (Computer Aided Transceiver) control for connecting to transceivers to allow real-time management of band, frequency and PTT etc. CAT can be two way-so changes on the Radio are shown on the PC software and vice-versa. CAT uses the controller serial port so no special drivers are required.<\/p>\n
4) Dedicated connections tor connecting HT (Handie Talkies) that will also provide serial port programming of the HT with CHIRP or the manufacturers software. Makes such as Baofeng and Quansheng will work with this.<\/p>\n
