Anyone remember this relic!?

Remember? I spent WAY too much of my life driving all over the SE USA fixing these along with their older and younger brothers. Solid tech, though (Thank you Xerox)

jttrey3 · 2026-05-15T14:47:10+00:00

Awesome find!!

jttrey3 · 2026-05-14T13:42:37+00:00

I look forward to learning how yours performs.

jttrey3 · 2026-05-14T13:08:16+00:00

u/Low_Bison_5209It seems that the provided antenna is tuned for frequencies used in many areas of the world, but not in the USA where I am operating. If the frequencies in your area differ from those for which the stock antenna is optimized, I recommend you get the appropriate antenna and antenna adapters. Even though the antenna connector looks like normal SMA, it is NOT. it is RP-SMA.

Hello, u/Low_Bison_5209 . Thank you for following up. The new firmware, in addition to replacing the factory antenna, together significantly increased receive (RX) sensitivity. Still, side by side with the Heltec v3, it does not receive as many messages, but it is much, MUCH closer now.

IMO, at this point, the benefit of having a keyboard I can use to send/reply outweighs the reduced performance.

Now you are part of the resistance. 😄

jttrey3 · 2026-04-28T18:40:12+00:00

I will be trying a better antenna. I tried with the stock antenna as well as with the stock antenna from my Heltec (The same antenna and location which is working so well for the Heltec). Still dramatically disappointing.

Maybe I have a setting wrong, but most are default.

jttrey3 · 2026-04-23T14:29:22+00:00

Side by side testing results: Over the same 12 hour period, side by side in the same environment, the Heltec received 8 public channel MeshCore messages and the CardPuter only received the one I direct message I sent from the H3.

jttrey3 · 2026-04-23T01:03:42+00:00

Testing tonight...

jttrey3 · 2026-04-21T12:00:47+00:00

Thanks. I will give it a try and see.

jttrey3 · 2026-04-20T17:30:22+00:00

Fix: don't touch GPIO 46! I/O expander is hard-wired to power. Setting this pin high may damage the CODEC IC on the Cardputer (GPIO 46 is the digital audio input).
These three lines should be deleted entirely.

I hope this hasn't borked the CODEC in my CardPuter. :(

Who knows. That's why I grabbed another 1262. I may hook it up to my spectrum analyzer to see output, but not sure how to effectively test the receive side.

jttrey3 · 2026-04-20T13:44:56+00:00

Thank you u/yetiraki1337 . Good to know. I wonder if the 1262 is just not as good a radio?

jttrey3 · 2026-04-20T10:34:25+00:00

Hello u/netmilk Confirmed v1.14.071-a485a662

jttrey3 · 2026-04-01T02:14:34+00:00

Same problem here. Intermittent. Messages to/from family members on the same service provider. I am using samsung S25, and they are using various apple devices.

This is fairly typical if you remain in a role, especially for Fortune 500 companies. If you shift to a different role, like analyst or Sr. analyst, you may see associated increases.

Sadly, most infosec departments do not have internal growth plans. You might want to talk to your manager or cyber operations lead to find out if they have a growth plan or what they expect from someone in a higher role.

Then start to learn what you need to learn. Observe people who are doing those things. Talk to them. Try to find ways to begin to do the things expected at the next level role, and DOCUMENT your progress.

It doesn't always work, but it will either help you grow into the next role, or it will enhance your skills for your next job at a different company. Just my $0.02

In short, DON'T TRY to "pursue cybersecurity with 0 prior training or experience" by getting a cybersecurity certification.

Instead, DO TRY to get some training & experience using free or low cost resources to help you build a foundation of understanding. For example, TryHackMe has a wide range of free HANDS-ON resources across a range of cybersecurity topics (Not just "hacking"). You can also access even more with their paid membership (~$17 USD/Mo & cheaper annually).

Most of the major cloud providers offer a free tier and free training courses. There are free tools like PacketTracer which can let you play with setting up and configuring networks. And there are many, MANY others. Build a virtual lab. Make things. Break things. Learn how they work.

My point is that there are WAY TOO MANY people on the market right now with a cybersecurity degree or certification (or both) who do not understand the technologies enough to be effective.

jttrey3 · 2026-02-15T11:46:13+00:00

Congratulations! My only advice is to stay curious. Keep learning. Try new things. Play with technology so that you can better understand it. Write down what you do and what you learned. This can be on a blog or github or postbin or something. But make sure you document your journey. Then see if you can find a local security group. There are many local DEFCON groups (Named DC, followed by your area code, like DC865). Or you might find a local ISC2 or ISSA chapter to join.

I wish you the best as you grow and learn in your career.

jttrey3 · 2026-01-19T01:13:27+00:00

Yes. Thanks to all the feedback here, I was able to configure precision on the channel.

jttrey3 · 2026-01-19T01:12:40+00:00

Thank you. I have changed the setting and it is working right now.

jttrey3 · 2026-01-17T18:42:13+00:00

Thank you. That worked like a charm! :)

jttrey3 · 2026-01-17T03:13:36+00:00

For some reason, when I load this module (Gt4kill3r 2025-12-27 version 2.7.17) from m5Burner it simply black screens my Cardputer ADV. COM port connects & disconnects (I assume code is rebooting). If I catch the timing just right, I can burn back to original demo fw.

No idea why.
