content: Hope it all goes to planEngine is built in the UK by Moog-ISP. Jupiter is quite active in the 10MHz to 25MHz region and all you need is a 20MHz folded dipole to pick it up, and probably a fair bit of back end processing to filter out all the man made interference.http://www.spaceacademy.net.au/spacelab/projects/jovrad/jovrad.htm

content: Juno has reached Jupiter and is currently sending back data at 100 bytes/sec at a received power level of -157.77 dBm. Simply amazing!Although I guess what is more amazing is that Madrid is currently receiving data from Voyager 1 at 159 bytes/sec over a distance of 20.15 billion kilometers.

Simply amazing!"On HF my minimum discernable signal is about -126 dBm so I would need a minimum of 32 dB antenna gain. VHF is a couple of dB better but with lower noise. -158 dBm is a signal of about 2.8 nV

content: Quote from: EEVblog on July 06, 2016, 02:36:37 amGreat idea! It might be worth while speaking to a bloke by the name of Colin Mackellar (colin@honeysucklecreek.net).He can tell you a lot of interesting stories from Honeysuckle Creek Space Tracking Station and probably put you in contact with others. I think he lives in Merrylands (NSW) these days. This guy was also instrumental in restoring and producing DVDs of the Apollo 11 EVA footage. I have copies of all three discs; very interesting viewing. He is a very accommodating fellow.For anyone interested in a bit of history:http://www.honeysucklecreek.net/station/index.html
