New ham here, only been on the air for about a month. I am having a ball making contacts all over the place. Seems to be a pipeline from my antenna to Italy. Even had a couple contacts in Hungary. Well, about 7:30 p.m. today I was minding my business and just trolling 20 and 40 meters and decided to check out the 17 meter band. Heard a couple weak fading signals earlier this afternoon. There was one signal fading in and out calling CQ. I listened for a few minutes and he finally hit a decent 3/4 by 7ish signal and I answered. We connected and exchanged signal reports and he said 73 and was gone. I ran his call sign on QRZ and, unless I totally screwed up his call sign, the guy was/is in Cuba--even has his picture. I don't know what to make of it. Apparently, Cuban citizens can have ham radios with a lot of restrictions which would explain his not engaging in any chit chat. Going by his call sign, he holds a first-class license equivelent to our extra license. Is this something kinda special? A friend said I should log it on QRZ but I don't know how/where to do that. I'm sure it is a coincidence, but there has been a black van with dark tented windows parked in front of my house since about two hours after the contact... Should I be worried???
