For the tx you have to use the correct hex code, see here
and be aware the battery symbol for the 7805 in the rx is wrong polarity.

Hi
well I have not built the whole project, so I cannot tell you about the depth of this project
Jon has added an opamp in the RX and said it worked better, there are coil details on the website
also be aware there are 3 schematics, and put the damping resister across the coil, not shown in all
schematics, try it on 12v first, if i get a bit of free time i will try and complete the project.
I used the baycom programmer for the attiny

You can read a bit more about it here
