Re: Sputnik 1
Coincidentally, I popped into the Media Museum the other day whilst in town. Tim Peake's taxi is in temporary residence. The parachute requires three floors to display, although only partially deployed.

Re: Sputnik 1
Regarding the anniversary, this is the eQSL card from R60SAT which was on the air on the amateur bands last week to celebrate the occasion. I was a bit disappointed that they used one of the stock eQSL photos rather than something a bit more appropriate. I don't think there are any lakes like that in Asiatic Russia...

Re: Sputnik 1
In the realms of transmitters on spacecraft, I wonder how many people on the forum might know that back in 1972 one Apollo spacecraft flew around the Moon for a few days dangling what looked like a 2m Yagi and a 40m dipole around its back end?
I was totally oblivious of this until quite recently, but this was an early ground penetration radar experiment flown on Apollo 17. It transmitted on 1.5, 15 and 150MHz. I subsequently found one photo where part of the Yagi can be seen, but I've never found anything where the dipole was visible. I believe the latter was unfurled rather like a steel tape measure. I think it ran about 100W out, so even if they could have attached a microphone and put out a "CQ", I'm not too sure that many of us would have heard it, even in the pre-wallwart era!. B
