Video Pre-Viewing The 817Companion App Logging Features

Hi everyone,

Julian OH8GEJ is testing and reviewing the development I’m doing on the 817Companion App for Android.

The following video shows you part of the logging features:

The new way to enter data will probably also be ported to the KX3Companion app as well.

I’m actually very focused on finishing the development of the 817Companion app and I’ll probably be able to release it in one or two weeks from now.

I’ll keep you updated on the development and new features I’m developing. As said before part of the new features that I’m developing for the new 817Companion app will also be ported to the KX3Companion one.

Thanks again to Julian and the other beta testers that are helping me in to all the people contacting me interested and suggesting features for the app.

Stay tuned!

Use A Raspberry Pi2 and KX3 Companion App To Remotely Control The KX3 With Audio Streaming!

Hi Everyone,

thanks to Trung W6TN I’m able to show you detailed information on how to control remotely your KX3 using a Raspberry Pi and an Android device with KX3 Companion in it.

Here are the instructions by Trung W6TN:

These steps are only about the audio part of KX3Companion Remote. (the remote control part is here:

I used three devices: an Android phone (OnePlus One), a Raspberry Pi2, and a Macbook Pro. I bought a USB Audio card from (via Amazon)

  1. Go to this website to install both Mumble Server & Mumble Client on the Raspberry Pi2
    There is a link to where all Mumble Client for different OS are there.
    Note: There is a circular way to install Mumble Client for Raspberry Pi2, you can click on the “Download Linux Client Version 1.2.8”, which will lead to another link
    Essentially, the command is “apt-get install mumble” or “sudo apt-get install mumble
  2. Install a Mumble Client on Macbook (or Windows-based computer)
  3. Install Plumble (a Mumble Client) on an Android phone (or tablet)
  4. Force default sound module to be disabled and the new usb sound card is enabled by following instruction here:
  5. Adjust input and output level of the USB sound card by following instruction here:
    Use an iPod or sound source (like Pandora from a smartphone) to play continuously while recording a test as suggested on this link. Remember the card number of the USB sound card, more likely zero (not 1).
  6. Run Mumble client from multiple devices: Pi2, Macbook, or Android phone. Try testing connection at least from the Macbook and the Android phone.
  7. Run the recorded sound test from Pi2 and listen from either Macbook or Android phone. Adjust the volume as previously stated.
  8. Finally, start from fresh then either run KX3Companion first, Mumble second or vice versa

Thanks a lot again to Trung W6TN for spending so much time testing the solution.

It works great and simply needs a Raspberry Pi2 (maybe it also works on with a Raspberry Pi but haven’t tried it yet) and a USB Audio card for it.

Enjoy it and please report  your success and problems so we can try to help you setup your complete KX3 remote solution 😉

CW Stick Keyer

Hi everyone,

Today I got a new toy for my portable CW: a CW Stick Keyer. This is an absolutely cool and perfectly working touch paddle.

Works like a charm! I’m used to a Palm Single paddle so it’s perfect as I’m used to mono paddle keying (no squeeze). I personally love it and find it the perfect solution for portable operation.

It also very inexpensive: 12Euro + VAT (+shipment)!

I did attach it to the Yaesu 817 so that I can also rotate it when it’s time to pack everything up.

I just ordered another one for my YouKits HB1B 😉 Probably I’ll add a few magnet at the end of the CW Stick Keyer so that I can attach and detach it easily to the HB1B.

Details and all info

Size: 100 x 19 x 2mm
Weight: 6 gr + cable
Cable: 60 cm
Connector: 3.5mm stereo jack

You can find it here:

There you’ll also find 3 YouTube videos showing it working.

There’s also a PDF flyer here:

817 Companion App: First Video Preview

Hi everyone,

my friend Julian OH8GEJ is one of the very few people that help me in testing my apps during the development. I really need those friends testing them and suggesting changes/features and reporting bugs.

He just published a video with a very first preview of the app running.

Enjoy it and stay tuned for more videos and post detailing the new app.

817 Companion Android App In Development

Hi everyone,

finally I’ve found the time to work on finalizing the “817 Companion” app.

Here’s a list of the features:

  • control of the Yaesu 817 ( change band, frequency, mode)
  • memories (10 memories for each band)
  • audio spectrum/waterfall (4Hz wide) with touch QSY
  • DX Cluster with filters and touch QSY
  • parameters settings

I should be able to pst some screenshot in the coming days.

Control could be done via USB Serial or Bluetooth Serial.

If you have any idea or suggestions, I’ll be more than happy to hear them and integrate into the app.

One Year Of App Development

Hi everyone,

One year ago I published my first app for Android: the KX3 Companion app. After one year I can say that 1 out of 10 people owing a Elecraft KX3 in the world, use my app. That’s a great success for me.

Everything changed since then. I loved so much to develop apps for ham radio that in just one year I developed 5 more apps:

  • KX3 KeyApp – a virtual keypad for your Elecraft KX3
  • WSPR Beacon – the only WSPR signal transmitter for Android to check band propagation and antenna performances on the go
  • CW Beacon – automatically send CW beacon messages that can include various information
  • QRSS Beacon – send very slow CW messages that can be hears at very long distances using very low power
  • Morse Machine – the app that let’s you learn CW as if it’s a game. Very funny and most important… it works!

Those are my apps for ham radio but I also developed one for my “day job”: the Forex Dashboard to check currencies (and stock indexes and commodities) strength/weakness in real time over 6 time frames with alerts.

Feedback from all the users has been great and is keeping me updating the existing apps and thinking about developing more.

I’d like to thank you all for that and for keeping supporting their development.

I’m already working on new apps that will be out in this second year of app development. Most important I’ll start publishing the iOS ported version of some of my Android apps: the Morse Machine and the Forex Dashboard first.

Happy APPniversary!

Morse Machine App On #NoAgendaShow !!!

Hi everyone,

Listening to episode #700 of my preferred podcast NoAgendaShow, I found out that my Morse Machine app has been nominated by my friend Adam Curry (@adamcurry).

You can listen to it at 2:57, but I suggest you to listen to the whole show and follow the show every Thursday and Sunday, if you did not already, as it’s worth every single minute spent listening to Adam and John C. Dvorak.

I’m very honored about that.
