    I am needing to know what this white tube's actual name is. I believe it is a frequency adjuster.

    hi there
    welcome to the forums

    The white tube is just a bit of plastic tube that supports the coilv (inductor)

    Excellent, Thank you for letting me know what this is so I can use a crystal for the 390 MHz mine took a dump, and I am too tight to buy one so I was going to make my own.

    I dont see a crystal on that board
    are there any other components on the under side ?

    if not ... it may just be a free running oscillator

    There is nothing on the bottom of the board just solder connections.

    The chip is a early solid state rolling code remote Tx module, the coil is there to fine tune the frequency...

    What are you trying to do?

    My other one broke and I was wanting to make my own, they cost 30.00, cheaper to make. Unless you know of a good website to make my own garage door opener.

    yeah ok

    the coil is slug tuned

    the problem is .... you have no idea if this remote TX is on the same freq as your existing one. There's every chance that they are very different

    That remote is a rolling code, it's paired to the receiver unless you system is using the same chips it's not going to work, and if it is using the same chips you would not need to modify it...

    As for remote cost, I have no idea of your brand or model number of your garage door system (FYI they are NOT all the same) but you can get universal remotes for pretty cheap just match it up to your system, they are well bellow $30 all over Ebay or even Amazon.com

    It's an old school remote, try contacting some garage door installers in your area they might have a drawer full of used ones that were reclaimed from swap outs...
