Stereo recording incorporating 2 recordings made simultaneously on the Web SDR (software defined radio) in North East Pensylvania (FN21mh) at http://K3FEF.com:8901/and the one at RAF Hackgreen in Nantwich in Cheshire (IO83RA) http://hackgreensdr.org:8901/
I used the filename of one of the recordings for part of this new dual receivers recording mixed in Goldwave and time-synched by ear. Left channel is the Pensylvania receiver, right channel is the UK receiver. Heard are various stations working or trying to work W1UUU in Massachusetts including stations in the Dominican Republic, Argentina, the Ukraine, Trinidad and Tobago, Colombia and Florida. Some stations are heard better in PA, some better in the UK. Lots of static crashes heard from late spring lightning storms hundreds or thousands of kilometers away from both receivers.
You can find over 100 receivers at
http://websdr.org/
Most allow you to record, though some have a 15-minute timer.

Yep! Actually I've been doing them for about a month or so, but haven't got around to uploading yet, but when I heard Larry give his web site and mention SDR's, and he was playing back recordings of his contacts so they could hear how their signal was being received for him, I thought, hey I'll put this up and tell him about it on his contact form, I imagine he'll find it interesting. He did, I just got an email reply from him. This site websdr.org is a windfall of receivers, I even found one in China, but it's not listed as such. I had to poke around and calculate where roughly the listed grid square was. Then I switched my synth to ESpeak and it told me the site was all in Chinese. There are loads of receivers in Russia, including Siberia, one in South Africa, a couple in Australia, many in Brazil, one or 2 in Argentina, one in Israel, and lots in Europe and the US. You have to dig a little sometimes because their location isn't always explicitly listed.
I've even found some microwave receivers, and a radio telescope in the Netherlands that loops a tunable recording of hams at the Arecibo telescope in Puerto Rico working hams via moon bounce on 70CM band at 432mhz when the moon isn't visible from the Netherlands.

No problem. Yep you could do that, and use the other receiver's record feature if it doesn't have a timer, but then you may run into synch issues, there's always a bit of discrepancy in the record rates of different programs. I've even come across this with certain paired receivers, the recordings slowly slide out of synch.

Thanks for this..it is pretty useful, and the links too.
Guessing one can get around 15 min timers by recording straight to Audacity.

You did it!
I remember you wanted to do a combined stereo recording from 2 listening stationd for ages!
Funny: I just discovered the same website a few days ago and was considering doing the same thing, based on your earlier suggestions ;-)
