Since the technical part of the Technician and General class license exams were identical (when I passed the Tech exam), the FCC offered me an easy upgrade to General without having to retake the exam. So, I arrived at the designated place ready to fill out a form, pay a few dollars, and receive and instant upgrade. Instead, one of the volunteer examiners suggested I take the Extra Class exam instead. Same low price. If I failed the exam, I would still get the General class upgrade as a consolation prize. Great. However, there was a small problem. Since I didn't expect to take an exam, I hadn't studied. I was fairly certain that I could pass the theory sections, but there were some questions dealing with rules, operations, and on the air protocols, where I wasn't so certain. I borrowed a calculator and began guessing answers. After checking my answers at least 3 times, and probably changing some correct guesses to incorrect answers, I decided that it was time to give up. Much to my surprise, I passed the exam. I was now an Extra Class license holder. I was then informed that this entitled me to change my call sign. However, I couldn't just pick my personalized preference but had to take the next available call sign in the pool. It wasn't great, but was an improvement over my previous call sign: <https://wireless2.fcc.gov/UlsApp/UlsSearch/license.jsp?licKey=2482894> So, if you know anything about electronics and RF, and can memorize some arcane FCC rules and regulations, you can certainly pass the General class exam, and probably also pass the Extra class exam.

Great.Yeah, they were OK with me taking further tests that night to move on up but I hadn't studied for 'em and it feels bad to just make guesses. Plus it was relatively crowded at the testing location that night; about a dozen test-takers and maybe a half-dozen guys proctoring (seemed like more than necessary), a number of both weren't bothering with masking, and the room at the local fish & game was small enough that I didn't much feel like spending more than a half hour there, it was during the winter 2020 case surge.> However, there was a small problem.

I received a nice welcome Radiogram in the mail soon after from "Kate" K6HTN in Pasadena CA, my girlfriend though that was very cool and old-timey.

But, then I thought: "And what am I going to actually *do* with this, given that my waking hours are already spoken for... I'd much rather listen to some good music than hunt for idle chatter!"

Why not go for it?Frustratingly they weren't doing remote tests during the winter surge and I didn't feel like hanging around too long. Next scheduled one is mid July and I think I'll go back for the general at that point
