Logger and Logbook
The SBITX V2 has a logger and logbook with RDMS support. N1MM style logger with macros and automatic logging of contacts with the frequency, mode, time automatically filled in. Use macros on CW / RTTY / PSK to send out standard messages with the press of a button / key if needed.
Telnet
See the spots, DX clusters on the radio with in-built telnet to DX Clusters, Reverse Beacon, PSK Reporter, etc.
Hackable code, skinnable GUI
Write custom apps in JavaScript without learning SDR coding.
Open source, hackable SDR written in C.
Develop your own skins and UI in HTML/CSS/JavaScript.
More modes and functions planned.
Access and operate your SBITX V2 over the home Wifi
With your SBITX V2 connected to the home Wifi, just open http://sbitx.local on the browser of your phone/tab/pc and start operating your radio! With the bigger screen of your PC or tablet, you can have an expanded user interface of the SBITX V2.
Accessibility & Command line support
The SBITX V2 project is committed to providing eye-free usage for the SBITX V2. As a first step, this release features a command line interface that provides all the features of the GUI.
Brief Specifications
Well, it is a different approach to the GUI user interface, and the radio as same as the software itself is still under development and improvement. So, we expect some bumps on the road for early adopters. However, having a large 7 inches screen and RPi on board will make this a fine radio to use in the shack.
Anyway, it is an interesting project. Time will tell, how the radio works and if it proves itself in practical operation on the bands.
...ONE MORE THING
HF Signals was founded by Ashhar Farhan, VU2ESE. HF Signals Co. is based out of Illinois, located at 44W, Doral Drive Apt 202, Glendale Heights, IL 60139, USA.
HF Signals manufactures all radios in Hyderabad, India and they works with a collective of workers. Each of the toroids is hand wound in India. This provides these working women with a livelihood. The assembled boards are then DC checked. A final RF check and tune-up is performed to check the receiver’s sensitivity as well as transmitter’s output before being shipped. Each board is individually numbered and signed by a radio ham who tests them for performance before they are shipped.
There is an active and very informative forum for learning and getting help that is entirely driven by the builder community. Join the group on https://groups.io/g/bitx20
