Made to Order
As there was so much effort involved in creating the tester I would like to let others benefit from it as well.
I'm open to providing identical or modified copies (e.g. different frequencies, deletion of mini-gauge support, larger case, kmph vs. mph, etc.) to those interested.
Note that it's just a hobby project but I'm nevertheless looking forward to any requests or ideas
