if I buy the 315 MHz Wireless Data Modem Transmitter and Receiver Kit for Arduino
how do I program it so that when I turn it on it acts as a permanent booster/signal extender
so essentially works just like wifi booster
when turned on finds RF signal and sends it to transceiver which sends out signal to nearby RF unit

Did you mean "sends it to transmitter"?
The key problem here, is where the transmissions originate. Because, you have to decode a packet before you can retransmit it. Do you know the protocol? That would be the case if the source is another Arduino sending packets in a format dictated by your software. However, if it's from a consumer device, you don't know the protocol, and then can't decode packets.
So, you need to tell us more about what you need this for.

Wifi operates on descrete frequency channels. A booster/extender may receive on one channel and send on a different channel. No decoding necessary. Can your device do that? Nearly impossible to do that at 315 Mhz.

here is some more info
so my project is RF transmissions. basically my goal is to receive 130khz signal . transfer it wirelessly to a device and transmit that signal
from there receive a 315mhz signal and transmit that wirelessly to another device
pretty sure I have the components for the later part figured out
just have to figure out code
https://www.amazon.ca/dp/B00LNADJS6/ref=cm_sw_r_cp_apa_i_Y6575JWHZX151PWWKYJT
but I can't find anything to transmit / receive the 130khz signal
Your description is quite confusing. The more I read it, the less I understand- and then you throw in 130kHz?
What is the source of the 130kHz signal? What country are you in? (315MHz is not legal in the U.S.). What protocols are involved?
A block diagram might answer a lot of questions.

You write about a 130kHz signal gives the impression there is some kind of encoded, digital, information in that signal. Is this correct? Then you write of not being able to find transmitters/receivers for 130kHz. Of course not, since transmission on that frequency is limited by international law to specific uses. General population uses is not one of them.
Why not disclose what your REAL project is, so someone can give reasonable answer

What is missing? Why doesn't it work for all your project? Please explain better than you have, so far.

that is the 130ish ( 125-135khz) signal captured and transmitted
next I need a 315mhz signal captured and transmitted
I see lots of devices that can do the 315 here in Europe but I don't see anything that I can buy to do the low frequency

And with good reason. They would be illegal to use. Just a few milliwatts and a reasonable antenna will allow such a signal to be heard half the world away.

At no point do you seem concerned that your 130Khz 'repeater' could interfere with other essential transmissions or is legal.
Why is this ?

Just because you can buy them does not mean they are legal to use.
no i dont care about legality. I'm not mass producing a product to sell, its a proof of concept done in controlled environment
how exactly is 125khz illegal anyways
pretty sure use of rf id keycards/key tags is legal
i dont really care about second frequency as long as its a common one so I can test with different devices
315 . 433
You still haven't said what your mystery project is, so we can only guess. And we're likely going to be wrong.
I am just tired of following this in circles.
Good luck.

Thank you for clarifying your approach to your project.
