Gary Spiers – M0TIG shows us how to install the Helitron DV$mini and tt’s software. He also shows us how to do a basic set up and how to get it working.
DV4mini is a tiny but powerful USB stick that can change any PC into a HOTSPOT for the modes D-Star and DMR+ (C4FM Fusion is being prepared). It contains a powerful 32-bit micro controller as well as a complete 70cm transceiver and modulator/demodulator for GMSK and 4FSK (including raised cosine) as well as a USB interface. It does not require its own power supply as it is powered through the USB interface. Thanks to a power saving voltage transformer even older USB interfaces will suffice. It will be shipped with a comprehensive but simple to use software package which allows for the linking with DCS reflectors for both D-Star and DMR reflectors.
For Digital Voice enthusiasts: Your handheld radio is no longer gathering dust. This hotspotbrings the D-Star or DMR reflector directly into your shack.
For DV Power Users: It is possible to plug several of these sticks into a PC, thus allowing simultaneous operation with several reflectors (even D-Star and DMR mixed). Well if you so desire you can fully use all your USB sockets with DV4minis and create a DV Center that way.
For home brewers: The DV4mini runs well on single board computers e.g. Raspberry, BananaPi, Odroid etc.The minimum requirement is a Dual-Core. Such a hotspot would only need a few Watts and be useable in continuous service.
For developers: The interface between the PC and the DV4mini is disclosed. With the DV4mini one can transmit and receive digital data in the 70cm band, without regard to the mode, as long as the mode is coded for GMSK or 4FSK. That means one cannot only transfer digital voice but also data. Your phantasy is the limit. The interface between the GUI and the DV4mini software is also documented and available.
For vacationers: Due to the tiny size it can be brought with you on your vacation and thus create a hotspot in your hotel.

A very generous subscriber donated an RTL-SDR DVB-T TV Tuner dongle to the channel (Thanks John N!). This video gives a very brief introduction to these very inexpensive software defined radios. These little receivers can be picked up for $20 (or less!), and the software to run them is available for free, such as SDRsharp (SDR#) and HDSDR. A couple of very good links to get you started, including a really great “getting started” page which walks you through, step-by-step, getting your first RTL-SDR up and running:

A few months ago I did a video on an SDR unit that www.radioddity.com sent me for demonstration. In that video I showed how the unit worked in VHF and UHF but failed to get it working in HF mode (my failure). I gave the unit to a buddy of mine and he got it working in the HF mode – this is his video.

An introductory overview of Software Defined Radio (SDR) is given by Schuyler St. Leger at Desert Code Camp at Chandler-Gilbert Community College. The hour-long talk covers what SDR is and how it differs from hardware radio, SDR hardware available today, software tools to use with SDR HW, and live demonstrations of how to use SDR.
