A $114 all-in-one D-Star, System Fusion, DMR, and P25 hot-spot digital modem dongle

All,  I just got a hold of a neat little gadget available on ebay for $114 shipped (from Hong Kong).  It is a fully integrated MMDVM (multi-mode digital voice modem) on a board that interfaces with a Raspberry Pi Nano single-board computer.   It comes in a tiny case with an OLED display screen, and a UHF ducky antenna.

This is commonly known as a Jumbo-spot and can be found in DIY format for around $45… (you add your own Pi Nano @ $15, an 8GB SD Card @ $9, and solder 2 headers and 1 antenna connector…and you can be on digital modes for $75 or so)

SO…what can you do with this dongle?   Well..many digital repeaters are networked together….and connected to various “chat rooms” and “reflectors”.   Thus, a virtual congregation of hams from all over the world meet up.   However, some places may lack a repeater (or like many students, you’re limited to a simple D-Star, Fusion, or DMR handheld without the ability to install outdoor antennas to reach the regular repeater).

No problem — all you need is this dongle, a  5V wallwart, and a WIFI connection… oh, and your regular dstar or fusion or dmr radio.   You configure the dongle to connect to the internet and connect you to those various reflectors/chat rooms of your choice using a user-interface known as Pi-Star.

The small hotspot dongle connects to your radio on your choice of VHF or UHF frequencies (simplex in most cases).  Thus, the ‘last mile’ connection is from your HT / Radio to the dongle and is done with RF.

What results is an HT that is truly global-capable as long as the internet connection is available.    Some guys are even using mobile WIFI/LTE hotspots to take their HT mobile while staying connected every step of the way through the D-Star, Fusion, or DMR network.

What’s more:  a College hamradio chat room has been created on the DMR network – node 9500 – to allow college club stations to communicate with each other, to network, and to have fun.

Boat Anchors….

A recent visit to Mike, WB0SND’s ham shack.  This is  half of the “boat anchors ” on this side of his ham shack.  Just a few toys, eh?  How about the AM transmitter – a bunch of  813 ‘s modulating some 4-400’s.   This thing loafs along at the legal limit of 375W AM carrier.    It will do double that (3KW effective DC output) without breaking a sweat.

I just want to know what brand of  desk he is using.  That’s some heavy metal !       Mike was a member of the University of Missouri, Rolla  (W0EEE) club back in the day.    He is active on most contests and uses the old gear often !

Do you AM ?     Give 7.290 Mhz a try !

A $109 HF all band SSB and CW Transceiver from India! Meet the UBitX (micro Bit X)

Wow.      For $109 you can get on the air with 10-15 watts of RF, covering all ham bands.  SSB?   CW?   Digital modes?   No problem !!   QRP?   QRO?   Also No Pproblem.

The opportunities are endless.

How about putting this in a box, along with a single board computer (pi, other) and a small LCD screen, antenna tuner, SWR meter, an LIFE4PO battery  and have an all in one, battery operated  fully digital HF station?   I just ordered one of these — I prevously built the BitX40 and it worked great.   Want to learn more?



Ready to buy one?  Go over to the HF Signals web site, check it out.
