@Kaushlesh Chandel - we are seeing a lot of projects that really get excitement from kids. High altitude balloons, ISS contacts, fox hunting, kit building, ... it just takes motivated mentors/elmers who will work with them and make it fun/interesting.

Kaushlesh Chandel12:41 PM
I've looked into the Bluetooth tnc ( couldn't buy any yet ) I am not suggesting one device or another... just thinking of how can it be easy and fun ( turn on, and it works ) for a Gen Z

Jan Weber12:42 PM
AATiS is a great concept, should be copied all over the world. That’s a German non-profit organization bringing ham radio to the schools by offering teaching material and low-priced kits with a ham radio and STEM orientation

John Hays12:42 PM
@Jan Weber -- Do you have contacts at AATiS?

K2LCT12:44 PM
LoRa APRS seems strong in EU but I have not seen much of it in the USA!

Jan Weber12:44 PM
@John Hays : No. but have a look here: https://www.aatis.de/content/

John Hays12:44 PM
@Jan Weber - Thanks

Mark J Hughes12:44 PM
KE6WOB -- Sorry I'm late!

Steve Stroh N8GNJ12:45 PM
@fid There is this, which is essentially a portable radio's internals controlled by Arduino and serial port ATDT commands - https://www.hobbypcb.com/index.php/products/uhf-vhf-radio/rs-uv3a

KC1AWV12:45 PM
@K2LCT - I actually worked a lot of LoRa APRS last year using an STA call I applied for. The ability is there, but the power limits are pretty restricting. You'll need high andtennas and a clear freq. bandwidth of at least 125 kHz to be effective.

John Hays12:45 PM
BTW - this project has been very successful and the leader would be happy to share experiences https://www.ampr.org/grants/2021-grants/grant-m17-open-protocol/

Dan Maloney12:46 PM
No worries @Mark J Hughes. And welcome!

John Hays12:46 PM
Sorry (wrong paste). This one https://www.ampr.org/grants/2021-grants/grant-engaging-and-educating-youth-in-amateur-radio-through-hands-on-space-science-activities/

Dan Maloney12:46 PM
And FYI all -- I'll post a transcript after the chat in case you want to refer back to any of these links

If anyone has any questions on M17 please head to our website m17project.org and link to our discord

KC1AWV12:47 PM
Hi @John Hays :)

Mark J Hughes12:47 PM
How do we get in touch with you outside of hackaday?

Mark J Hughes12:48 PM
I have a project that I'd like to see accomplished -- but no time for it myself. Perhaps you know some people who can help?

John Hays12:48 PM
@Steve Miller and I have a german ham that wants to build FIDOnet on top of LORAwan but needs developers (he is primarily a tech writer).

fid12:48 PM
Thanks @Dan Maloney . A transcript would be great.

Rosy Schechter12:50 PM
@Mark J Hughes contact@ardc.net, and our website is ampr.org

KJ7CLT12:50 PM
That uv3a board looks like a fun prototyping to build with GnuRadio.

Mark J Hughes12:50 PM
Thanks!

Rosy Schechter12:50 PM
:thumbsup:

John Hays12:50 PM
I have a hard stop at the top of the hour. If there are any specifics for me. You can also reach out for grants at giving@ardc.net or me personally at john.hays@ardc.net

KC1AWV12:50 PM
@John Hays LoRaWAN, or LoRa the modulation? I'm going to be honest here, I'm against using closed protocols (LoRa is owned by Semtech, and was only exposed through reverse engineering) - but something like FIDO on LoRa is possible. I mean, we're only talking the PHY layer with LoRa. I'd suggest taking a look at Reticulum Network Stack, I've been in contact with Mark Qvist off and on about it and is very, very interesting.

Kaushlesh Chandel12:51 PM
I am a long-time programmer... I did a lot of work on Arduino's, Raspberry pi's Lora, BT, Zigbee, SDR's, et al. Ill be happy to work on interesting projects.

William Stearns12:53 PM
@Steve Miller I believe that's all under the non-profit now as a standard.

Mark J Hughes12:54 PM
@Kaushlesh Chandel Please email me markjarrodhughes@gmail.com

John Hays12:54 PM
@Steve Miller - we are all about open source, and any development of software / hardware that we fund will need to fall under that umbrella. However, most radios are full of proprietary components so existing technology will sometimes be intellectual property encumbered -- we would have a hard time funding something like a repeater if it had to have no IP in it, from a pragmatic point of view.

KC1AWV12:54 PM
@William Stearns Oh, interesting. If it's a well documented modulation type, it's possible it could be used on amateur bands.

Jan Weber12:55 PM
@KC1AWV : What’s the use of a crypto networking stack with respect to ham radio? I thought ham radio communication is ought to be in clear text?

Kaushlesh Chandel12:55 PM
@Mark J Hughes I just emailed you.

KC1AWV12:56 PM
@Jan Weber The encryption is not intended to hide the message, rather allow the network to work. Anyone on the stack can see and monitor messages, AFAIK. There's a discussion about it in the RNS github.

John Hays12:56 PM
@Jan Weber in the US at least, encryption to obscure the meaning of the content is prohibited. Command and control can be obscured to my understanding.

Kaushlesh Chandel12:56 PM
I second @John Hays . Was about to say that Ham communication cannot be encrypted

Thomas Shaddack12:57 PM
What about steganography? Encoding a hidden (possibly encrypted) signal on top of a cleartext message, in eg. a phase jitter?

Kaushlesh Chandel12:58 PM
Steganography is good... It would need a much larger image payload. And again... its encrypted and not legal

KJ7CLT12:59 PM
Thank you

Rosy Schechter1:00 PM
Hey folks, I have to hop off. Thank you so much @Dan Maloney for having me and @John Hays on the hack chat! It's been great chatting with everyone.

fid1:00 PM
I thought I should share my call sign. K6FID. I might see you on the radio. :-)

Thomas Shaddack1:00 PM
The point of stego is to not get caught.

Dan Maloney1:00 PM
You bet, I was just about to call time. Thanks Rosy!

fid1:01 PM
Thank you @Rosy Schechter . It was an interesting topic.

Kaushlesh Chandel1:01 PM

Rosy Schechter1:01 PM
thanks @Dan Maloney and @fid

Rosy Schechter1:01 PM
bug us with grant proposals ;)

73 , thanks for the chat

Dan Maloney1:01 PM
And thanks to John too! I really appreciate your time today, as well as all the great questions from the crowd. Thanks!

John Hays1:01 PM
Yes, I have another commitment now. Thanks everybody, I will leave the chat open, but not see a question due to multi-tasking -- 73 to all.

Mark J Hughes1:01 PM
73's

Dusan Petrovic1:02 PM

@Jan Weber - I found the discussion that I mentioned here: https://github.com/markqvist/Reticulum/issues/69#issuecomment-1167083780

Jan Weber1:03 PM
It’s getting late here. Good night!
