I would like to get in on this, but from a blind persons perspective. I know the H1 line is far wider than what the human ear can hear, but my ears can probably pick up something in a sound scape that might not be noticed by someone watching a waterfall. It's a differing technique to sight. believe me, I find this field of study highly interesting.

btw, as a teen (and fully sighted back then), I had a Tasco Brand 1500mm Cassengrain telescope and I spent a lot of nights in the back yard looking at some of the more interesting objects in the night sky. I really do miss that and would certainly want to enjoy it again, if only by touch and sound. DE n7zzt Eric

I think I just mentioned some experience with this. Note that NOT chopping off the bitching, pissing, and moaning is the best way to keep the group going. It helps keep people more relaxed and more focused on the group than the (GISP) CENSORSHIP! We're all people. We're all anxious to one degree or another. Unlax, develop a sense of humor, and go with the flow. Life becomes more fun when you can do this. That is what makes mailing lists much nicer than forums. If things get nasty remove the nasty one from the group. Otherwise, let it flow. When it MUST get serious, it will. So sit back and have a nice coke, 4 degrees C. Whose the barkeep here?

It's a general dynamic for lists and forums. When something has been promised at an indefinite time in the future some people bitch at the delays, some people say "Second Tuesday next week" (some being me at least), some people say they want to wait to get it right, some people turn smartass (me at least), and some bail minutes before delivery. And I watched this for so many years trying to soothe ruffled feathers that I can't always resist contributing to the mess now that it's not my job. The consistent behavior of humans leads me to note that IPIO, Innate Perversity of Inanimate Objects, has a brother, IPAHS, Innate Perversity of Animate Homo Sapiens. {^_-} IPAHS!

It appears mine shipped, too. Now, who is going to bitch that it was shipped too soon?

Thank you, Robert for all the invaluable information! I belong to several technical google,io groups other than AirSpy. They have all migrated from the older yahoo groups which are going away, if they haven't already, to the google forums. Yes, we have SARA and a few other dispersed resources online and in books and publications, but possibly we might (suggestion) start a moderated google.io group specific to ARA. RadioJove really sticks to 20.1 MHz, although many spectra are published on that forum which cover above and below 20 MHz with nothing said (myself included). I have learned an awful lot from the other groups, non ARA, to which I belong. I'd propose just beginning to think of the possibility of starting a moderated ARA-only google,io group. There is SO MUCH to be discovered using an SDR re solar and Jupiter emissions than just a single-frequency receiver like the RJ receiver. I started with the Icom R-7000, but once I purchased my first 8-bit USB dongle, I was hooked on the SDR technology. I've so far been through two AirSpys one damaged by ESD (USB) and the other by a close-by lightning strike (front end). I have a third and love it! Example: We recently 'fine tuned' our H1 receiver system and dish feed at LTO in Berthoud, Colorado. We have a 14' off-center fed dish. I was amazed to actually SEE the H1 line painted down the waterfall of SDR# from one of the Galactic arms. A single-frequency receiver in no way can visualize the roughly 260 kHz bandwidth of the thermally spread line centered on 1420.405751 MHz! But, we really need more bandwidth for radially Doppler shifted deep space objects other than the Galactic arm. Again, thank you for the references. I need time to digest the list, but I really do believe we should pull everything together in an ARA-only group. Dave Eckhardt - WØLEV Volunteer: Little Thompson Observatory (LTO)

Secondly I would venture to guess that most people out there beginning experiments in ARA are using simple systems based on hacked Sat Finders or products like the RAL10KIT from Radio Astro Lab, to me these are totally clumsy and inferior solutions that belong back in the 20th century! There isn't a whole lot of people out there using SDR for ARA, although that is changing and SDR will ultimately be the main tool for ARA as more and more people get comfortable with the new paradigm shift in RF thinking. --

Anyone hear anything about shipping to USA addresses from airspy.us yet?

Re: My HF+ production unit just shipped

Orders #691 and #791 shipped for me too.
DHL has impressed me before; hopefully they are consistent... LOTS of packages flying around the world at this time.

Meduzi Jellyfish <iain@...>
That seems normal. They do indeed roast along. In fact I've thought about building one into a round base and selling them as the "Airspy Cup Warmer".

Us Hams waited 14 months for our Icom IC-7610 radios, now shipping… So these delays for this unit is not a big deal.. J

Amazing the amount of people who don't get or understand "pre order" and the lay of land. It's not built yet, there will likely be delay, it's a small run. I think they just want to be seen complaining. E-ragers. :)

Airspy mini very hot?
Andrew Sutcliffe
I have had my unit running for longer periods lately and it gets really hot - almost too hot to touch.
Firstly is this normal? Secondly, if yes above, what is causing this heat? An overclocked chip? Linear regulator? If that latter, could I swap for a 662k 3.3v 500mA switching regulator? I have used these on a lot of things lately and they run nice and cool and stable. Any other thoughts or ideas I might need to know or could try? Thanks. :)

Pre-order sales. Notices of shipping are going out. And still some people won't be happy unless they get a hand
delivered unit in a personalized engraved presentation case.

So far very few seemed to have shipped. Order 100129663 is still processing...
Ho Hum... Enough words have already been said. My opinion will only feed the numerous trolls on here.
