Re: PicoAPRS, world's smallest APRS Transceiver with KISS TNC

Hi Stanley and thank you for the reply!

I'm NOT using the Dorji module, but handheld for now and the plan is to use mobile radio. Schematic I used is on post #87. Only part that not work is decoding packets. Is the audio level too low for the input of ADC (pin A0) of the arduino or i miss some part in the soft?

BR,
Ivan

Ivan,

How are you troubleshooting this issue ?

If you clip on A0 and you should hear the sound from the APRS Test CD ...

A few factors affect the packet decoding ... noise from power supply does affect it ...

I knew you followed the circuit diagram and coding word for word , parts by parts ...

A picture of your circuit would help us to troubleshoot the issue ...

Most of the time, it was just a small connection that screw up the whole thing, e.g instead of putting the 100k to both Vcc and Gnd, both were on Gnd or something ..

Was wondering if there is any love yet for the ATmega2560 smile

Re: PicoAPRS, world's smallest APRS Transceiver with KISS TNC

The 2560 has enough resources and features to run the firmware, but as of now, there is no mapping for the pins and specific ADC and timer settings. If you can figure this out yourself, you can definitely run it on the 2560 smile I'm going to add support for other boards at some point, but I just haven't gotten around to it yet wink

Yea no problem with working on that myself. If you give me a quick run down of what I might be needing to look at changing, I'll get on it.

Re: PicoAPRS, world's smallest APRS Transceiver with KISS TNC

Hallo
Zuerst vielen Dank für dieses tolle Projekt! Soweit funktioniert alles einwandfrei. Da ich nicht so gut im programieren bin, habe ich ein kleines Problem : Die longituge ist bei mir einstellig. Es wird also z.B. llo 07.00 gesendet. Sollte aber doch llo 007.00 sein. Wie kann ich das ändern, dass sowohl z.b. llo 010.00 als auch llo 007.00 gesendet wird ?
Vielen Dank !

Hello
First, thank you for this great project! So far everything is working properly. Since I am not so good in programieren, I have a little problem: The longituge is one digit with me. It is thus e.g. Sending LLO 07:00. But should it be llo 007.00. How can I change that, both as LLO is sent 010.00 and 007.00 llo?
Many thanks !

Re: PicoAPRS, world's smallest APRS Transceiver with KISS TNC

Update!

My project is nearly 100% finished.
Maybe the smallest APRS TRANSCEIVER (not just "tracker") on this planet?

Again: THANK YOU MARK for make this project possible!

I really hope this ends up being made for sale as a kit and a fully assembled option.

Re: PicoAPRS, world's smallest APRS Transceiver with KISS TNC

Taner and all who are helping in any way. Thank You for working on this.  I am excited to see a tracker this minicule!!!   I have some digging to do on this, but I want to learn and boy would I use these on several events here in the USA.  Small self-contained units for bicycle races, wheeled runners and marathon chase vehicles.  I can see many more uses for these units.
I am excited about this!!!  Ko4L Lloyd

Re: PicoAPRS, world's smallest APRS Transceiver with KISS TNC

Hi Lloyd,

thank you smile
I'm currently developing a more enhanced version of my APRS Transceiver! I will not publish to much at this moment. But what i can say is: it will the same size with a lot of more features and possibilities!
You will love it.

I received many many inquiries from all around the world about my project. So i think i will make it available for purchase. Maybe a kickstarter project also!

Give me some more weeks for developing. I can only work on evening after my job on this project.

Re: PicoAPRS, world's smallest APRS Transceiver with KISS TNC

Wow, i'm really impressed!
More than 70.000 klicks to this topic since my first post. THANK YOU :-)

Some news about my project:

- i have redesigned my PCB and made some more improved prototypes.
- i have made some nice changes which allows a lot of more really cool features (i will tell more about it later...)
Now its a more improved APRS Transceiver!

I currently examining the prerequisites for the sale of the product. I think it will be a KIT (SMT components pre soldered).
Unfortunately this is a very complicated matter in Europe :-(
If you can help me to sell this with observance of all laws, please contact me!

Please see my website for news about this (www.db1nto.de).

Hi,

is someone from here on Hamradio in Friedrichshafen from 24. June to 26. June 2016?

I'm there... So if you like to see the Transceiver live & in action, meet me ;-)
