They have excellent training. I learned everything I could about cabelling. When the cable installer tried talking down to me when my cable modem wasn't working, I ran rings around him and got straight answers.
This is my latest experience. I am on a Fire Dept (Vol). When my county went to 800 MHZ trunked radio I investigated and bought a scanner that was PC programmable. I sent 10 other people to RS with the proper part number and model number so I could simply clone my scanner to theirs using a cable. 2 out of the 10 were sold a different scanner that could not be PC programmable. They were incorrectly assured that the scanner they bought was compatable when it was not.
