Thanks for the video! The problem why is your radio not receives on the end is that, an external antenna have to be connected to the pad of removed tiny capacitor. If you not remove this capacitor you should be able receive HF signals trough the original SMA connector but signals will be not so loud as from external connection. 😉👍
Well done on the mod Andreas, I can appreciate how tricky it is! I think your not getting any signal due to removing that capacitors you mentioned at the start. Also, I have the same soldering iron as you and I found with the small tip it just doesn't get hot enough for the job. Did you see my latest video of me doing that mod? Although not ideal, I used a slightly larger, blade shaped tip.
@M0FXB ... The (de) soldering ai ai ai ... Tip: a quick and much cleaner way is to use "desoldering wire" (fine grade) , Put it over 4 pins on one side of the IC ... press your solder-iron on the desolderwire, it will then suck up the solder from all 4 pins ... then do the other side 4 pins ... use the length of the iron to equally touch the whole wire above the 4 pins ... this is in general how its done with SMD formats .. (all Multipin IC's , all SMD-Resistors, SMD-capacitors, and pcb SMA RF-connectors) ... First try this desolderwire technique on some broken pcb, maybe 30 mins to get the feel of it ... this is the (prof) clean way ... no risk of damaging the pcb-tracks ... and the components come off clean and re-usable 😏

Hi thank you which pad should I use ?

Thanks was fun I may add antenna rather than replace the chip .

May thanks I will try that .
Use Kapton tape to mask off areas before using a heat gun, that way you don't lose components.
Ok
Whens part 2 ? I have a version 2 board arriving in a few says.
Lol yes antenna next .
Is it possible to use an external HF antenna with the original antenna connector without installing an additional connector in place of the LED light?
Yes but there is a diode you do not remove .
@@HamTechRadioScannerDrones Which please?
Interesting.
These sets are so cheap it's good learning .
Will you do the 2.5 Chip Mod? 73
Maybe
Send me one of these wow
Fun
You need a camera man

Great video, Andreas, Thanks!
Thanks was tricky lol.
