🔴 Cobra 29 Ltd AM/FM CB Channel Modification - Hardware Hacking - No.1227

[@robertpittman5040]

Really dude no one else has done it. You say that whatever other Radio you mess with I watched a few of your videos today you would be surprised. Nice hack job.

[@TheDefpom]

Do you know of anyone else that has modified the AM/FM version… I don’t. And as I explain in the video, it was a prototype, if I were to do more of these I would be getting a PCB made to tidy it all up. And the reason you have seen me claim to be the first more than once, is because I was! Like it or not I have been a leader in CB modifications for decades.

[@Alan-bn6ii]

it would be a nice rig if it had ssb as well

[@Tricktrucker]

Thanks again Scott for your awesome talent and efforts. The radio looks and works great in the truck and certainly was the topic of some conversation at the recent Kenworth 100 year anniversary truck show. I cannot overstate how grateful I am for your work on this and can assure you this radio will be treasured. Cheers mate

[@TheDefpom]

It was great to be able to do this modification to your radio, yes it was a lot of work and time involved, but it was worth it ! I really enjoyed getting this done, I love getting my teeth stuck into a tricky task such as this from time to time.

Excellent work, Scott. There is a real sense of satisfaction when a project like this comes together and works. Well done! The interrupt issue makes sense, I used an interrupt scheme in my GPIB printer emulator but didn't have problems with debug output to the terminal, but this was a much slower chip I was dealing with. Something to file away and try to remember. Regards, David

[@TheDefpom]

I was tempted to drop the interrupt implementation and rely on the main loop to handle everything in a more linear fashion to prevent timing issues, but it was basically working by that point and the guy needed the radio back urgently so I didn’t have time to improve it to where I wanted, I’m still pretty happy with it though, it’s about 95% to where I wanted it to be, just a couple of bits I wanted to improve on.

Well done Scott top job, as we both know Mark Rutherford will be interested in this and may very well have a go at it. He definitely has the knowledge as we both know. Cheers from Pete in QUEENSLAND.

[@TheDefpom]

I might design a PCB for doing this if I get time, rather than the patched in module I did to get this done quickly for the owner, I certainly would have tidied it up a lot more if I had more time but they needed the radio back urgently.

[@guidozambonin5949]

Hi Scott, has the channel editing been finalized? Is it possible for you to send the modification

[@mostlypostie1]

Very impressive work! You could always just buy a ARES2 or QT40, but hey, this is great hacking. Well done.

[@TheDefpom]

Thanks

[@MicroChipz]

Nice work there :)

[@TheDefpom]

Cheers

Hi Scott have you ever read the data from the uniden 980 and put the esp32 in it. Thanks for your videos

[@TheDefpom]

No I haven’t done that, I know Mark was doing replacement front boards to hack them.

[@CbRadio-w6v]

Ok yes I seen marks but. I thought it would be cheaper with that esp32 if I remember he used a bus pirate

[@Edisson.]

😲WoW you're good, I don't do RF technology at all, firstly I don't understand it and secondly I don't have the equipment, but I was swallowing every word. I'm old school analog and Arduino is a dirty word for me 🤔 maybe it's time to get familiar with it. Congratulations on your success and thank you for showing absolutely perfect work. Nice day 🙂Tom

[@TheDefpom]

Thank you.

[@craigshagey9999]

Nice work 👏 👌 👍

[@TheDefpom]

Thanks

[@tommyboy9998]

Bets on how long it will take for the USA screwdriver Experts to start attempting this without crediting the Defpom?

[@TheDefpom]

If I can do it so can someone else, it really just required a decent knowledge of RF and serial communications, and a bit of programming.

[@zdzisiek1979]

Ładne CB radio :)

[@apollorobb]

Reminds me of back in the day when we were Hacking the president Lincoln/2510 and the RCI 2950 . Hey is that a prototype or is that as tidy as you would like it lol

[@TheDefpom]

I actually have a bunch of MPU from those radios, got them off a guy doing chipswitch mods years ago.

[@wireless80211x]

Why does my CB have a yellow dot sticker ? 🤣

[@JamesEverett-o3n]

The channel nob is trash

[@TheDefpom]

@@JamesEverett-o3n it’s a rotary encoder, just like a lot of other modern radios.
