+This is hacker public radio episode 4,121 from Monday the 20th of May 2024.
+Today's show is entitled Road Wireless Microphones.
+It is hosted by Clinton Roy and is about nine minutes long.
+It carries a clean flag.
+The summary is, my first recording on newer microphone.
+All right, well, good evening hackers.
+My name is Clinton and this is a very off the cuff episode from me just to announce that
+I've got a new microphone.
+So I just wanted to run through a couple of details of that, make a show, say a little
+about the microphone, why I got it, what I had to do with it.
+So this is a roady wireless go to setup.
+It comes with three little boxes, roughly, roughly you could fit each one of the little boxes
+inside a matchbox.
+So there are three of these that come with the set that I bought, two of the microphones
+that you clip onto your lapel, the third is a transceiver.
+So at the moment I've got the transceiver on and I've got one of the microphones on.
+I bought this because I'm going to be going to a conference soon and one of the things
+that I do try to do at conferences is do interviews with people.
+And this is kind of nice in that I can switch these two microphones on, give one to myself,
+give one to the person I'm interviewing and I don't have to use a single microphone
+and shove it underneath their faces and I don't have to swap the microphone between
+the two of us.
+The other feature, like the particular reason I've got this model is that each of the two
+microphone units actually has built in RAM.
+So it will actually record, like if you've got it set up in the mode, which I do, you
+can get each microphone to do a backup recording of your presentation.
+The regular mode for this set of microphones is to actually treat the transceiver as
+a source and plug it into your computer or plug it into your camera as an external microphone.
+But it has this lovely mode, which I'm recording this particular episode too.
+We can just turn it on, the transceiver is not plugged into a computer, it's not plugged
+into anything and it'll record something like 40 hours of voice and later on I can hook
+it up to my computer and as a standard mass storage device and just download the waveform
+I believe.
+So it does have some Windows firmware or Mac firmware.
+I didn't have too much fun getting that to work under Linux.
+I tried under a couple of different VM products and wasn't having any luck, so I tried
+under wine, I tried under open box, eventually I did end up installing like a full Windows
+10 install onto a QMU image and that had enough stuff working, such that I could install
+the Rody firmware on it.
+That let me do an upgrade of the firmware on the two microphones and the transceiver because
+the first thing you do when you buy something these days is out of the box you have to upgrade
+the firmware because why would they do that at the factory before they send it out when
+they can just make the users do that?
+And there is a phone app but it does not let you update the firmware on these particular
+hardware models.
+If I remember the error message correctly, it does look like the Android app lets you
+update the firmware on other Rody microphone devices but not this particular model.
+So I had to go down the track of setting up a QMU.
+I did find a good blog post on how to set up a Windows box on QMU.
+It had a few things that seemed outdated so maybe it's a job for me to write an updated
+blog post on how to do this, if for nothing else instructions on how to do this in future
+when I need to rerun the firmware update.
+The other thing that I really needed to use the software for though is to switch on the
+recording option.
+So out of the box these things do not record to the memory that's built into the
+microphones.
+So I had to get, I had to update the firmware and then I had to run the software on both
+of the microphones to switch on the recording option.
+But now that that switched on I can just hook it up as a USB mass device as I've mentioned
+before and presumably I can just copy the files and delete the files and I won't actually
+have to run that software.
+So there's a number of options going forward so I can write that blog post with the updated
+details, there were a number of hoops that I found that I did not have to go through
+of the blog post I found so things are getting easier over time.
+Depending on how in depth I want to go I could potentially one day sit down and install
+like a USB listening device and see if I can work out how to work out if there are
+any magic packets getting sent to do the configuration on the device.
+Like do I need to break any sort of crypto stuff or is it just a straight command like
+plugging the device and send a command with a few funky options.
+So maybe in the very distant future when I've got no other things on I could try and
+work out a pure USB non-windows solution for setting some of these configuration options.
+I'm not sure I'd go down the track of updating the firmware I think that's probably a little
+bit too risky but you know maybe one day in the future but yeah basically this set of
+microphones assuming that it works out okay assuming that it sounds good I'll hopefully
+be using these for conferences coming up hopefully as well I'll be able to use it for
+camping and stuff like that so if I'm out and about I'll just be able to pull out these
+two things, transfer, microphone, a couple of clicks, turn them on, they talk to each
+other wirelessly and then start recording something.
+So it's much smaller than the current microphone that I'm using so it's much easier to travel
+with.
+There are two of them so that when I'm interviewing someone it's much easier and it's
+got recording memory so I don't actually have to plug them into a computer so all up
+it should be much easier to use I think it might even give better recording outputs
+and hopefully like increase the number of talks and presentations that I give on HBR.
+So that's been Clinton this has been a very off the cuff recording I very much amused
+to sitting down and writing out a full script for these things so I'm doing this because
+you know it's cool new hardware but you know also because HBR needs more episodes.
+So yeah maybe other people can do an episode on what particular funky wireless or what
+particular microphone setup that they've got that they enjoy using and what the advantages
+are and disadvantages are.
+That's it for now, ciao.
