Web-888 Network SDR Now Available

[Robot Matrix]

I think I'm going to pull the trigger on buying one of these from AliExpress, along with the GPS antenna. My Ham-it-up upcoverter is way too sensitive to temperature fluctuations and causes too much drift. I'll just use the NESDR SMART for VHF/UHF, which seems fine,  and maybe sell the upcoverter on ebay or something.  Perhaps the upcoverter would function better in a box, but I can't imagine it would make it that much more stable. You can literally hear the drift when tuned to WWV when the heater kicks on. Not good! I'll let you all know when I get the new SDR and I'll put it online.

I did order the WEB-888 from AliExpress. Says it shipped out on the 18th. It was cheaper than on eBay.... and all coming from China either way, as none of these units ship from the USA.

In preparation for this I bought an SD card and an active GPS antenna.

EDIT: Came in TODAY! I wasn't expecting this till Feb, but it arrived in 5 days. I wasn't ready for it as I haven't got all my parts in to assemble the new antenna I'm going to build for it. My ears don't hear well below 3-5 MHz as I'm using a TV 4:1 balun for my temporary dipole. I'll day this.. it's ACURATE!

So, I've tried a mobius loop antenna, which was way too quiet without a preamp. I settled on an inverted L, though I'm not sure a 9:1 unun is correct, given it's not a pure end fed antenna. I'm not sure you can make an L a broadband antenna. It is disturbing how much noise is present in the lower bands, like from 160-40m. But when it's clear,  it's CLEAR. I'm going to keep refining this as per numerous articles on this topic. I have HORRIBLE noise below 500kHz, which I suspect is from the dirty power supply and from the HVAC motors from my house and the neighbors'.

Aa far as the VHF tuning, I built a 1/4 wave groundplane centered on the phone portion of the aviation band, and it performed perfectly!

I'm VERY impressed with this SDR. I don't like how it's missing some features that the Kiwi has.  I'll leave that for another topic. But,  so far,  I'm pretty happy with this purchase.

Listen in sometime at http://75.134.33.242:8073/ . No guarantees that this IP address will always be valid,  but feel free to give me some feedback on the reception. Currently, I have it set up to do 0 to 30 MHz.
