[amsat-bb] USB SDR DONGLE - Re: Exclusive New Product Launch at AMSAT-UK Colloquium

I have been working with some of the new low cost RTL2832U+E4000
dongles that are flooding the market. It appears that they are
designed for the digital TV market in some countries outside the US.
They cost about $20. They usually come with an antenna and a remote
control. The antenna and remote are useless but the dongle does work.
It has a PAL antenna connector which is not a problem since an adapter
are available at Radio Shack.

It takes a bit of digging around to find the drivers. There was some
sort of license fight between a couple of "open source" developers
which makes it a bit more difficult than it should be. I have one
'working' with HDSDR. It is still a little funky changing frequencies
with the 'FreqMgr' but it is early days. The performance is the same
as the FUNcube. There are quite a number of different chipsets in use
so buyer beware.

If you like hunting for working drivers and ExtIO programs and
tinkering these E4000 dongles are for you. IMHO the FUNcube Dongle is
still the best bet for the rest of us. My FUNcube has been sitting on
the shelf for quite a while as it does not perform as well as my
receiver even with the help of a SSB mast mounted pre-amp and cavity
front end filter. I was talking with someone on FO-29 and they
mentioned they use theirs as just a panadapter. I dug my FUNcube out
and it does work well as a panadapter (no connection to the receiver
required). Very handy on those rare occasions when there are more than
zero people on the linear sats.

SDR-Radio v1.5 works well with the FUNcube . Very nice work by Simon.
I do miss the picture of him and his dog when the SDR-Radio program
boots up.

Very interested in seeing  Howards "FUNcube Dongle PRO-PLUS". I hope
the PLUS is not a price increase. In an attempt to find out what it is
before the official release I searched the net and came up with this
gem from 2010 on the http://www.funcubedongle.com 'Ordering FAQ' page.
Be sure to check out the link.

I am working on a Pro Plus version http://www.proplus.co.uk/ to enable
us to work 24/7 on the Dongle.

Thanks to all the Europeans who manage to keep out hobby alive and up to date.
