GPS data via BITX

Hello everyone, can we send gps data via bitx? thank you

Re: GPS data via BITX

Hello Resti,

It depends what you mean by "via bitx". If you mean without the addition of an external device, I don't know of such a solution, but it may have been done by someone. It is technically feasible with a serial gps connected to a beefed-up Arduino (Teensy for example), but I don't know of an existing software for the (u)bitx. The round the world balloon launching Hams have some simple solutions using RTTY and other modes.

If you mean with an additional device, and in that case via"any radio", this is what I use for sending positions over HF (now will be "via uBitx"..hihi): 

- On the transmission side  I use AndPskmail which is an Android app that uses the internal GPS of the phone. It uses a number of modes, some of which can easily be used in a phone's speaker to bitx microphone configuration to send position reports. A digital interface is better for regular position reports, but not essential for casual ones. I get good success with MFSK16, THOR11, THOR22 and MFSK32 for position reports depending on the conditions.

- On the receiving side I use jPskmail  which runs on Linux and Windows and I activates its iGate function so that received position reports are forwarded to the APRS network and can been seen in aprs.fi web pages for example.

For the receiving side you can use the more elaborate (and Linux only) Pskmail server (installation is more involved).

Hope that helps,

I would go with the rtl-SDR.com v3 dongle. I use it with my Yaesu FT-840. And I have about 4 others that make up my radio farm.  To me it’s the best design of the dongle type SDR’s no need to get the more expensive SDR’s like LimeSDR or SDRplay

Upgrade the software to Allard's version #radiuno #bitx40help #nano

SaMa photo SaMa photo
 

Good morning
I was advised to upgrade to the Allard's version
https://github.com/amunters/bitx40
that solves many problems!
I downloaded the zip and unzipped it then I installed the Arduino/Genuino software
 
Can anyone kindly explain to me step by step the procedure without losing the settings?
 
Please do not use abbreviations in the description because otherwise I can not translate the steps in Italian
THANK YOU

Update to the VK2ETA variation of Ian Lee's KD8CEC uBitx software #ubitx

John (vk2eta)
 

I have uploaded an update of both the Raduino and the ATU software in the folder  Variations on KD8CEC Software (by VK2ETA) + ATU sketch .

Is it targeted at portable and /PM operations. It is basically where I want it to be and I don't plan to add much further features unless they are of value to portable operations. 

If you want to use sections of code in your projects, follow the #ifdef/#endif segments that mostly enclose the sections of code of interest. I am happy to help with extraction of code if requested.

The software is organised in options that can be enabled/disabled (mostly) independently.

The key features added in this version are:
1. Reduction in libraries size by 1K byte (this allows for more features to be added in the limited memory of the Arduino).
2. Added a "Stock Standard" option for unmodified rigs wired as per hfsignals instructions.
3. Added a two adjustable levels supply voltage monitor with visual and audio indication. Level two will disable TX to protect the battery.
4. Added the WSPR beacon option from KD8CEC software version 1.061.
5. Changed logic for CW modes: frequency displayed is carrier frequency, with Rx frequency shifted up or down (CWL / CWU).
6. In split modes, the VFO A/B label and frequency change when going from Rx to Tx.
7. RIT display:  frequency is kept fixed, RIT is now shown as +/- frequency difference.
8. Added ALC levels for MAX level too. Used to be no attenuation.

All the best,

73, John (VK2ETA)

I am wondering if anyone know how to:
- enable FSK/RTTY interface to the radio?
- ptt out for amplifier??

Is there a schematic somewhere for this extra arduino / atu?
Would love to build it.

Hi SaMa,

First you must install the PinChangeInterrupt library in your IDE (the
Arduino/Genuino software).

The PinChangeInterrupt library is normally not installed by default. You
have to add it to your IDE by yourself. You only have to install the
library one time, once it is installed it will be kept on your pc.

In your IDE menu, go to 'sketch' => 'include library' => 'manage libraries'.
The Library Manager will be opened.
Wait for some time to collect all library information.
When it is ready: In the search box, enter "PinChangeInterrupt"
The Library Manager will show some libraries.
One of them is named "PinChangeInterrupt by Nico Hood".
Click on this library, and press the "install" button.
It takes only few seconds to install the library.
When installation is finished, press the "close" button.

Then setup the IDE correctly for the Raduino:
under 'tools' => board => Arduino Nano
under 'tools' => processor => ATmega328P
under 'tools' => programmer => AVRISP mkll

Connect a USB cable between the Raduino and the PC. Do not power on the
radio. Power to the Raduino is supplied from your PC via the USB cable.

Go to 'file' => 'open...' and browse to the folder with the raduino files
you downloaded. Find the file named "raduino_v1.27.7.ino" and open it.

The sketch code will be now be shown on your screen.
Go to 'sketch' => 'Upload'
The IDE will first compile the sketch (it will take a minute or two), and
then it will automatically start uploading it to your Raduino (this will
also take a minute or so).

When the compilation/uploading has completed succesfully, the Raduino will
restart and the new sketch version (Raduino v1.27.7) will be displayed
briefly on the LCD.

Finally, disconnect the USB cable, apply power to the radio as usual and
enjoy the improved firmware.

Happy BitX-ing!

Hello Ad,

Yes there is. It is in the older folder below. The file is called ATU Schematics and pictures.
 
It is a servo based ATU, not a relay based one. It works nicely, a little slower than a relay version, but with memory tune, stored in EEPROM, it is quite ok. Have a look at the description here: 
 
https://groups.io/g/BITX20/message/45705
 
Schematics are here:

All the best,

Hi Tim
I was getting 25 watts on my watt meter. om 80m.

Today hooked up a 10m dipole and got 2.5watts with keyer down. With a low swr.

Should be possible using Winlink Express.
Your position is input manually or via a GPS device.
This is then displayed on the Winlink clients Google map.

I had grabed a taperecorder mic with 3.5mm mono pin.
 replaced the cable with 2+shield.had a small pushed switchmounted and wired.

Hello John,

Checked the file ATU schematics and pictures.zip and find only one picture an no schematic.
Is this right.

No hurry lots of other stuf to build.

Many thanks :)
Done all, now I just have to connect the Raduino and load! :)
 
But doing so overwrite the already loaded software, if I wanted to save a copy of the original sotware in my PC is possible?
 
But the story that they say to save the calibrations and then upload them again because otherwise raduino starts from scratch?
 
Thank you very much :)

Thanks for the additional info.
I was only referring to the black wires which I tested for ground continuity.

The grounds for the arduino are located on several pins - marked gnd

The rig grounds are the black wires but i test them to be sure.

 

I keep my grounds short and tie them to the chassis. Either directly to chassis or using a small copper blank pcb as a bus or combination

But all my gnds go to a common ground.

 

Mr rule is I check all the black wires - to be sure they are common and go to ground as you say , the diagrams shows the audio to gnd and the black speaker wire shows continuity to common ground  --- so I always put them all to ground.

Hi,
Sorry if this has been addressed, but I have a question regarding the grounds on this board. Are the grounds for the Raduino (terminal 4) and the audio grounds considered common grounds? And can they all be tied together to a metal chassis? I believe I have read of people isolating the mike & speaker jacks from a metal chassis, but I'm not sure why this would be necessary The schematic shows the keyer jack grounded to chassis, but not the mike or speaker jacks. Is the lack of a ground symbol saying the mike & speaker shield terminals should be isolated? Thanks for the clarification!  Bill A.

Looks- Professional, but you are the "professional" Amateur.. I notice the volume control is pointing to "FUN"
Can you explain VRB ? T800 confirm - sidetone frequency?... Then what is S25? Keyer speed?  Red and Green are push buttons? VFO select and Function?
What is the filter for on standoff's at the BNC connector?
Great Job...
