Homebuilt ROVs Forum

so this PS2 controller system is working so i thought but after fully testing the RF signal is not going down the tether. Any advice i soldered the tether to what i thought was the antenna but not I'm not sure.

please help the board is a MAR105 C -1

i have a send to the rov after c124, i wonder what X1 is and under the wording "L122" i looks like that may be antenna?



What would you do?

x1 is a crystal (the silver can on the right).

soldering a wire to the antenna isn't going to work. antennas are tuned components. it may just look like a piece of wire, but it has very specific dimensions.

How's the rest of you control system set up?

Ive heard of guys soldering from antenna to antenna via tether.

that may work with a coax cable if the attenuation isn't too great, but a regular piece of wire won't work.
