This helped even though mine looked very different. The board had very very small components and was hard to distinguish what was what. However I did find the antenna. So I just traced the metal on board from antenna to the first component I saw. I just gently broke off the component hoping it was the resistor, and put a tiny drop of solder between the connection. It worked like a charm. Crazy range and super clear.
you did not bypass it you just added antenna .the resister takes the much of the signal to ground . remove resister ,attach 31.5 in of wire to ANT and 31.5in wire at GND. cut a pvc pipe to at least 63 in . mount transmitter to center and wires to ends . mount pipe so Ant wire points up. Huge range!
@user-ji6lz1vh8g For a antenna to work efficiently it must be resonant to the frequency transmitted or receiving. Typically a ham would have an antenna remotely mounted using a coax cable and some form of support . In other words, for more range (better signal at receiver.) Those wires added will allow more signal out of the transmitter . GND is the final negative terminal for the battery. The battery's are connected in series . Does this help ?
Planning on using the same transmitter on my upcoming project this holiday season, do you think the signal would be strong enough to be good at around 30-50m? I'm planning on connecting the transmitter on my computer and using a cheapo FM radio as a receiver outside. PS. I live in the city. I've checked the list of the current FM radio stations here and 107.9 is not yet taken. So, I wouldn't be bothering anyone. Thanks!
I did this to an old radio shack FM transmitter which had that exact same resistor. It's missing now and I have awesome reception. Frequency select switches are a little iffy though.
I have The same fm transmiter That you, but i want to know how voltagem That this device work on dc input because i lost my Plug dc, and how i improve rage? Just put one antena? Or i need to modify something, thanks i from Brazil.
By soldering the new line in front, he's bybassing the resistor. Alternativly, you could solder a jumper wire on both ends of the resistor to essentially remove it and use the original antena.
Sacas el resistor y en su lugar sueldas un pedacito de cable o simplemente soldarle un cablecito y voilá amplio tu distancia de transmision ( en los ee.uu. son estrictas las regulaciones sobre emisiones radioelectricas y establecen mediante la FCC un maximo y por eso muchos circuitos comerciales deben limitar esa distancia ) Lima Peru.

Im going to have to try that. Thanks for the advice
How long range?

That really is an impressive range.
i wonder how far it could reach hooking up to a roof antenna

put the wire vertical and it will act as a omni directional antenna .
I had this growing up

Looks like you added the wire to the GND pin..
Can see how that can make an improvement of the range...
Hi Mikael...So the best way to add an antenna would be to remove and bridge the resisitor...?
@@mikegrant5585 NO
Nobody can tell how far. FYI. Please just say a number for max distance. Lol
Am gonna start my fm channel now😂
Can u do a range test with that with a car I will subscribe
So did you remove the resistor or not? From what I can see it's still in there, mate.
