more good ham stuffs arrived lately – seems I’m getting a few things looked after and getting more in the mix. Earlier this week – while I was away for a bit – a package arrived at the door and in it was a nice new 5v 6 line usb charger – each with 2.4amp! woo hoo – that will take care of my continuing saga of power adapters/splitters for all these raspberry pi and other types of wall-wart units. I might be able to plug in some other stuff!
this guy can power 6 raspberry pi’s and ancillary devices.
I’ve been following some of the digital interfacing modes recently – those that work with pi’s and the like. I do have a mini-dv unit – which has sketchy programming interfacing at times – but I’ve seen some other types being produced within Canada. Bruce VE2GZI has been producing a digital interface board and now a hotspot unit with a 10mw transceiver on it that fits onto a pi gpio interface. So, I decided to pick one of these units up and check it out. Seems I’m not the only one interested in it – he’s been hit with a deluge of orders and has to rework the process to ensure smooth operations. But, I was earlier on in the order process so I was lucky to get one of the units sooner than not. Arriving in the mailbox one day was the following:
a kit with a raspberry pi zero w (wireless) and a pre-populated sd-card with the pi-star software on it and the digital iterface rf unit with antenna. This unit is a 70cm unit with 10mW output – so, nice to use around a local setting. I will have to solder the gpio interface connector to the board – but wanted to at least get the unit up and running and check out the features – so I turn to a spare raspberry pi 3 and hook it all up. Getting it onto my 44.135 local network on 2.3GHz and it’s all working fine. I configure my settings, location, call, dmr id etc etc and hook it up to the local dstar repeater in town to check it out. Lo-and-behold – audio coming through – so that’s cool. Now I have to program my DMR radio as well .. as this thing supports not only DSTAR, but also DMR, Yaesu system fusion as well as P25! So, more programming and setup to do, but it’s a functional system and will certainly open things up by being able to connect directly to a system/repeater.
Those that have an interest in running a pi zero wireless as a remote operation node and/or mobile on cell data, can certainly do it as it’s very very low power consumption – you can even run it off a battery for a long time!
More to come on that – once I get more tested and checked out.
For those interested in taking existing analogue radios and making them perform digital miracles – check out their MMDVM board that attaches to a pi and provides this really really innovative function: MMDVM
What really makes all this “tick” is the great software produced to support all these new digital modes. The ‘pi-star’ software is very very cool and is the software that allows you to control the units and interface boards.
Now, this stuff is cool. Not only do you get an easy-to-use dashboard, but you can also log into the pi and reconfigure what you want and automate what you want – that’s the great part about these units is that it’s so configurable it makes your life more fun for being able to image all kinds of cool interfacing.
Ah well – get your unit(s) while you can – with all the hype these days, there’s bound to be more and more and more interesting developments with computers and RF.
