Ham radio in Films & TV ?
by Paul Reilly 31 Jan '07

31 Jan '07

Hello again, I am looking for any references where ham radio is featured in popular culture, particularly movies, and TV. For example there was a bit of it in the movie "Contact" based on Carl Sagan's book of the same name. Has anyone got an other references like this? Thank you. Paul

I will be on the 349z and 524z passes tonight. I will attempt to bring up the PSK31 transponder and then call/copy my PSK31 CQ's , any RX reports(send to WB4APR), or TX (someone to talk to) welcome...

Re: Last AO51 pass 0110 z Unbelievable Ignorance
by Dave Johnson 31 Jan '07

31 Jan '07

Some people have the "me, me, me" attitude, so they feel they're entitled. I don't mind hearing a SHORT QSO between ops. I've kept this in mind when I've worked the same station a few times, and have limited my comments to them to a sentence or two, so that others get a chance to get in. Worse yet, on many of the passes that I can hear/work, there is someone in the footprint who just whistles, causing QRM on the already-crowded satellite. And then there's the op who does nothing more than say "hello...hello...hello". Lastly there are also the ops who apparently aren't hearing the satellite and keep calling CQ, with stations answering them to no avail.

AMSAT-NA QSL Beuro - Some Ideas and thoughts
by sraas＠optonline.net 31 Jan '07

31 Jan '07

I now have 2 people and myself willing to do some beuro work. Still looking for volenteers for call areas 1,3,4,5,6,8,& 9. Keep in mind this wouldent be anything like sorting 1000's of DX cards...but a great service for sat ops ! Thank you all for your input! -Steve Raas N2JDQ FN20vg AMSAT 36396
