I may have been in that class with you because I remember taking it, too. I was so excited that there was a component of R-56 in the class... and then it was like very minimal.
I only got called out once. It was a Saturday in winter and the HVAC unit was stuck in air conditioning mode instead of heat. And, that was that! I always seemed to luck out being on call. I always used to hear Lenny and Kevin complaining about being up all night at XYZ site with Motorola central dispatch.
And, admit it, that 60 second TOT on the shop 800 MOSTARs must've killed you, LOL! I liked the 900 SMRs better - and we could change the TOT value!
