Thanks Martin, David, and Howard. I really like the design and seamless integration. I built a TNC-Pi and love ouw it plugs onto the Pi header and becomes one with the Pi. I get a company like MFJ needs to make it worth their while- but for $100 I could buy 2 complete Pi3 and have money left over for a case and microSD cards.

:)

I hope to see an isolated design from N7SET that would be perfect. Fun to build- save some cash- sits right on the Pi.

Thanks guys!

Gosh, there is no question there are USB sound adapters for under $10.  I suspect the bill-of-materials for RigPi Audio board costs more than that, especially in a product designed for the amateur market.  I don't know anything about the details of MFJ pricing, but there are a number of factors that increase costs for any manufacturer.  Among them are materials, assembly and test, payroll, benefits, general and administrative costs, marketing and advertising, after sales support, plus any margins required for dealers and distribution.  Add a bit of profit in there too!.

 

Dealers are usually able to set their own prices, so I expect to see discounts for the RigPi Keyer and RigPi Audio boards.

 

If I were selling boards myself the price could be much lower.  I would rather spend my time making the best possible software experience.

 

The inexpensive USB sound interfaces I have tested seem to work well and will be fine for many users.

Sure will, Ronny!  In addition, feel free to send me a note through the RigPi web site, https://rigpi.net  Click the menu button on the right side of the top bar.  I'm compiling a mailing list for those interested.

You're you're getting pretty close.  I also know that know that N7SET has a version of the PCB that includes audio isolation as well but he hasn't released it yet.


Cliff Wareham's Easy Digi card will get you audio and PTT isolation for $9.95 (kit) or $15.95 (prebuilt).

Well if they are dumb enough to add a $100 sound device to a $40 computer fine.  Just my opinion.

The Raspberry Pi is supposed to be an experimenters thing for those who want to learn things.   Adding cheap isolation transformers and adding transistors to the GPIO for keying purposes isn't rocket science.

I'll continue to use the cheap USB sound fobs.

Thumbs down from me.  I'll be curious to explore the software when that is announced however.

Hi All,

 

This past weekend I was in Starkville, MS to introduce the new RigPi Server at MFJ.  RigPi is a Raspberry Pi-based server for hams.

 

RigPi controls all station functions, including rig and rotor control.  It has optional boards for keying (using the K1EL 'WinKey' chip) and an audio board especially designed for hams with transformer isolation and PTT circuitry.  These two boards will be available soon from MFJ.

 

In addition to station control, RigPi has logging, VoIP and US Callsign lookup.  The software will be free and open-source.

 

RigPi is compatible with CommCat Mobile and CommCat.  But here is the good  part:  all RigPi functions can be accessed through a web browser.  This means that you can use any computer including Windows and Macs, or any Apple or Android mobile device.

 

RigPi will be of interest for Go Box and emergency applications.  All functions in RigPi are available when power, Internet and Cell serviices are down.

 

The RigPi site is now live.  Take a look at https://rigpi.net.

Pulseaudio has seen a lot of changes since it was a hated animal when first introduced some years ago. Although generally (but not always) disabled by users of professional audio production suites, "modern" pulseaudio is capable of excellent results.

This article - https://wiki.archlinux.org/index.php/PulseAudio/Examples#Disabling_automatic_spawning_of_PulseAudio_server - contains a section towards the bottom on disabling/enabling pulseaudio on an as-needs basis, without actually uninstalling it. Perhaps this is a viable option for your requirements.

FWIW I've read of latency at least as low as 10mS when using pulseaudio. Google for "Linux professional audio" for loads of information.

Re: RPi3 Jessie - remove pulseaudio??

David Ranch <dranch@...>
 


The PulseAudio guidelines have been there since Raspbian Wheezy where there were many reports of audio latency issues, etc.  This also originates back in the day of the Raspberry Pi 2.  It's possible things are better in Jessie or Stretch so it's worth giving it a try (maybe even more so if you're using a Raspberry Pi v3).  Uless you're trying to do advanced audio settings like routing demodulated SDR audio to Fldigi, etc.. I think you'll be fine with either using PortAudio or native ALSA.

Re: Testing TNC-pi

John G8BPQ
 

Bob,

I’m not familiar with aprx, but generally you have to run i2ckiss to present
the TNC as a kiss interface to the application, either directly or via
kissattach if you are using the Kernel ax.25 software. I’d leave one TNC on
serial so you can leave that setting as it is, and tell the application to
use either the virtual kiss port or the ax.25 device created by i2ckiss.

73,
John

If I setup two TNC-pi's, how do I tell APRX to address each one with APRX?

Hi Bob,


If you only want to test the PTT LED, I would open a browser and put the IP number and port. 
(http://192.168.1.10:8008) Click on ports. Click on the beacon link to the port you want to test. Click test button. Watch the LED blink. 

You will also need the HTML directory and files present. The directory is all caps.

This can be done on the PI or thru ethernet on the same sub net.

If the test is good, you also know that BPQ is talking to the TNC.

I hope this helps. I haven't used it for a spell and memory is not as good as it was.

Take care,

Re: Testing TNC-pi

John G8BPQ
 

Bob,

Use ./pitnc_getparams 0 0 to access /dev/ttyAMA0. I suspect you are running
./pitnc_getparams 1 0.

The normal usage with the latest version is

./pitnc_getparams
usage for i2c: pitnc_getparams i2bus i2cdevice
usage for Serial /dev/ttyAMA0: pitnc_getparams 0 0
usage for Serial other device: pitnc_getparams device 0

Using 1-5 for device opens /dev/ttyO1 to /dev/ttyO5. This was added for the
BeagleBone Black version of the TNC.


The latest version can be found at

http://www.cantab.net/users/john.wiseman/Downloads/NewPITNCParams.zip()is

John G8BPQ

OS.  I am trying to reconfigure to use i2c.  When I run getparams I get:

Using Serial port /dev/ttyO1
Device /dev/ttyO1
Com Open Failed: No such file or directory

I can seem to get it to use port /dev/ttyAMA0.  Ive been through all the
