I've had a GROL license since 1994, and got it because I was told how useful it would be. In the years that I worked as an electronics tech., I was hopeful that it would advance my career, and increase my income. It made no difference. Even though it was one of the credentials listed on my resume, employers never asked about it. The folks in HR who interviewed me, didn't even know what it was. When they saw that I also had an amateur radio license, they thought that I was a member of a group that performed entertainment services. Anyway, the achievement of both licenses, has always provided me with personal satisfaction, if nothing more.
