OpenRepeater Project goes Beta!

This afternoon I received an email from the OpenRepeater project.


They have their first PUBLIC BETA ready for RaspberryPi B+, BeagleBone Black, and Odroid C-1.

I’ve yet to try anything out yet, but am VERY anxious, as I’ve been eyeing this project for a while, hoping it still had a pulse. As it turns out, it’s VERY MUCH alive!

Even the write-up and setup instructions are well-laid-out, thorough, and simple. You can see them as well as download an image of your flavor of choice at:

I’m super excited and as I’m typing this, I’m signing up for the forums section on the site.


More to come, I am very sure!



syncing mp3 files to the cloud!

So, one of the disappointments I have found with broadcastify / radioreference streaming is the lack of being able to listen to the archives of the stream.  (of course, by “disappointment” I mean “darn, I wish it was free.” I completely understand the need for the company to make money, and the need to offer “premium services” to achieve that. I digress.)

Since I’m generating mp3 dump files locally, and I’m trimming silence, why not pump these to the cloud into a shared folder?

Enter Copy by Barracuda to solve my issues. There’s a Linux version of the end-user client program.


Setting it up was trivial, I downloaded Copy.tgz and expanded it into a folder.

I made my synchronized folder “~/Copy” for simplicity.

For further simplicity, I moved the x86 binary folder to ~/.copy/ where config is kept (also a good thing to note)

Once it’s set up, invocation is simple. I’m running it live currently, under a screen session, and will probably daemonize it soon. For now, on a screen session, I invoke with:

~/.copy/CopyConsole -root=~/Copy


So, now after midnight, I changed the “dump path” of the finished file from the previous day to go to ~/Copy/Scans/2015/ where it is then detected, and synchronized to “the great big cloud in the sky.”


check it out here:

You’ll find a 2014 and a 2015 directory. There’s also a Misc directory (empty as of now) because I had some files I didn’t datestamp.


Sure, this isn’t as elegant as whatever time-stamped version of the “scanner wayback machine” that broadcastify uses, but it works and it didn’t cost me anything, and I own the archives. Always handy incentives. 🙂

MotoTrbo Traverse City repeater goes Beta-Online!

The N8OUZ/R DMR-MARC MotoTrbo repeater is on the air on 442.2875+ (input 447.2875).

you can find more info on DMR-MARC Here.

Currently on a temporary transmitter antenna and site, and with limited receive coverage, and limited transmit power.

But, it works, and you can test it.

Program your radios:
Time Slot #1 – Group Call 1 = World Wide
Time Slot #1 – Group Call 3 = U.S. / English Speaking Countries
Time Slot #2 – Group Call 2 =  Chicagoland Repeaters Only

The current transmit antenna is a J-pole at 40ft…. but…

Current Receive antenna, plugged
into the back of the repeater
in my basement..

The current receive antenna is a.. erm.. telescopic whip style scanner antenna standing… about seven inches tall.. plugged into the back of the repeater… in my basement…

Which might seem dumb…

But I can actually use the repeater reliably from work.
… how? I’m really not sure.. but.. I know TDMA has a lot better survivability than analog voice when it comes to getting through the noise floor in a usable way.

Check this out:

On the map, B is where I work, and A is the repeater’s home in my basement..

…I can use it!
With the HT on high power.
The HT on the right, in the picture!

Note the size of the antenna compared to the Yaesu. No vertical gain there at all..

Notice that the Yaesu HT sitting to the left of it is listening to an active signal, same frequency as the XPR 6550 HT on the right.. The signal is sometimes an S2. Usually S0 or S1, sometimes not even there.

Mind you, the length of the Yaesu HT’s antenna is more than three times as long as the Motorola’s!!!

If it were an analog signal, it would be unintelligible. But it is audible, clear, and readable.

I had the same experience on the drive in to work today. Notice on the map. Between “Best Buy” and the number 37 on the map above it, I was very shadowed due to the hills near where it says Grand Traverse Crossing and East/North of that. I had almost NO signal.. on my MOBILE radio with an external antenna in the car, I could barely hear the repeater’s signal. It was not present more than it was. if it was a voice, I would no way have been able to comprehend it. .. the Motorola HT, with just the stub duck, on the SEAT of my car, inside the car, just sitting there horizontally.. I could UNDERSTAND the audio coming out of it.

It’s been a good while since I’ve seen a digital mode so easily and obviously out-perform analog modes.  I’m very impressed.

I am anxious to finish getting the StationMaster antenna on the permanent tower, hardline up, and repeater moved to the final location…

tonight: duplexer fun! Perhaps even a better receive antenna. I still can’t believe it’s … usable! with no duplexer… from across town… from a whip in the basement!!



Repeaters in the Traverse City Area

** UPDATED 6/4/2012 **Here is a helpful spreadsheet that I started maintaining about a half year ago.
There is probably a lot of inaccurate information in this list, so mail me ( if you would like changes made.
This was compiled basically from dumping memories on my radio, cross referencing with web searches, etc. Nothing fancy.
What’s important is that right now (to my knowledge) the list of PL tone frequencies is accurate enough for use. Since things have been changing a bit in this regard in the region, I felt being a stenographer of sorts was necessary.
Hope you find it useful!
