FYI - GPS
GPS modification RT3s - final hardware, final instructions
hello,
I have two Retevis RT3s. One with and one without GPS.
Can you use it to convert both devices (with/without GPS)?
Is this the best final hardware for the GPS modification:

And is this the correct instruction ?

Hi Alfred
"And is this the correct instruction ?"

For the mod I made, yes, these are the correct instructions.
I just made one change, I replaced the backup battery with a slightly larger one with more autonomy.
With this mod, I am 100% satisfied.
However, there are other mods, also interesting, posted by some colleagues
Nice View!

Re: FYI - GPS
Is there a difference in the circuit board layout of the RTS3 with/without GPS or does the GPS modification work the same way on both radios?EU1AEQ wrote: ↑Sun Nov 19, 2023 7:51 amI have 2 radio stations: RT3S with GPS and 380UV without GPS. In RT3S I replaced the antenna, the amplifier, replaced the module with ATGM336H-5N-71. There are no special changes in the speed of satellite detection. It works very slowly. Finds up to about 9 satellites. In 380UV I put an external module with an active antenna. Satellites are detected in a minute. Shows more than 20 satellites. In both cases, the antenna is on the side. Something is wrong in the circuit diagram of models with GPS.
Many thanks to all contributors who made this modification possible!

Yes
As I explain in the tutorial, it is important to remove as much plastic as possible. Before a hole is left open. The antenna and module must be as low as possible.
Good Luck!

Comprehensive and clear manual
New manual
Hi everyone, EA5JOP and me (EA5JOQ) have written a comprehensive manual in both English and Spanish, step by step, covering the entire process for performing the GPS mod. Based on ''CU7AAZ GPS mod 2''.

https://ea5jop.es/files/rt3s_gps_mod.pdf
If there's anything wrong, you can point it out, and I'll change it. Moreover, the PDF will be updated if anyone encounters any other issues.
