Issue description:

It is currently not possible to use the Portable Teleporter on private frequencies, because the Teleport button is always shown dark grey, with the reason "No Link" at the top left.
This seems to be caused by either c086ae1 or fd225f0.
I verified this by testing the same thing with the 218e3f6 branch i had from yesterday, and then testing it with the updated fd225f0 branch, and the first time it worked, the second time it didn't.

Steps to reproduce:

1. Setup a Teleporter
2. Get a Portable Teleporter
3. Set it to the frequency of the Teleporter
4. See a dark Teleport button

Version (make sure you are on the latest version before reporting):

I just tested this again, and it doesn't seem fixed with your new commit.
