I could struggle through this but it appears the most painless solution is to upgrade Mint. Those are striaght forward but time consuming. I will do that on the weekend. Thanks

got this far.... will investigate more later.... I think Boost needs to be upgraded Desktop build # cmake ../ -- Build type not specified: defaulting to release. -- Could NOT find Boost CMake Error at CMakeLists.txt:94 (message): Boost required …

tried to build the gnuradio stuff on a Linux Mint (Ubuntu) X86 box.... got this: Desktop gr-kiwisdr # cmake ../ CMake Error: The source directory "/home/jim/Apps" does not appear to contain CMakeLists.txt. Specify --help for usage, or …

can you describe linear supply or upload a picture of it?

last year, I used a tool to convert json to csv, brought it into a spreadsheet, worked on it, then reversed the process. Can't recall tool name though

AI6VN's wsprdaemon.sh code really works well. The #1 wspr reporter in North America as of late, KD2OM, runs 2 8-channel kiwis and cover all 14 bands
-
20 KHz is available now if the Kiwi owner sets it up for that. I have my public one that way
-
further news.... the BBG supports Grove UART and I2C only, not analog and digital. That limits what Grove Module will work with a basic BBG.
-
I am pretty sure that AI6VN does that with success, I alerted him to your post
-
I have the Grove stuff working.... I just installed the latest debian stretch release. Obviously, as it needs stretch, my work so far has been on a bare BBG, not a kiwi

The problem with scanning and analysis is what metric do you look at: RSSI, SNR, BER? RSSI suffers from being a measure of the composite energy, noise+signal. More meaningful metrics are mode specific. WSPR was conceived for looking at propagatio…

NooElec has a MW band reject filter for $8.95

as this is just RX, the coax can be small making the winding around the ferrite core easy. US people, see: https://www.ebay.com/itm/20-RG316-SMA-Male-to-SMA-Male-plug-RF-Pigtail-Coax-Jumper-Cable-US-Stock/111711582126?hash=item1a028777ae:g:n8cAAOSw…

W-O-W..... very nice. Thanks so much for your continued efforts!

Looks like it works on normal Stretch using the mraa stuff. I have a BBG with jessie on it, I'll change it to stretch and advise

http://wiki.seeedstudio.com/BeagleBone_Green_Wireless/ has detail I need to explorehttp://wiki.seeedstudio.com/BeagleBone_Green_Wireless/

I believe it is off the shelf code, but let me confirm that
-
It is well past prototype now and the system has been fielded in PRC-160 radios now
-
The initial call is done on a 3 KHz 3G channel and then a WB BW is negotiated depending on regulatory restrictions on either station or the BW occupancy by other energy. It can result in a BW or 3-24 KHz with a data rate from 75-115,000 bps.

The Thales scheme is quite different from the MIL-STD, Harris and Rockwell schemes.

those signals eminate from just down the street from me, at Harris..... where I work! :-)

a screenshot of this might help us understand (Image)

who is the provider? Verizon, AT&T ?

WRT the popularity of 2G ALE... 1) US DOD no longer uses much of it 2) even when used it consists of a short period of signalling to set up a link and to terminate one. The actual communications can be plain SSB or many forms of data other than th…

Chris, I am on kiwi chat right now

There's this mess too that sounds like a mix (Image)

I bet WHVR is part of your problem. I built notches for those strong AMBC stations here. rx.jimlill.com:8073

The nice GPIO spreadsheet John had done seems to be lost in the archive here (?) http://forum.kiwisdr.com/discussion/discussion/590/kiwisdr-antenna-switch-extension-and-beaglebone-black-green-gpios/p1 < can't access

FWICT, the BBG will work with Grove but the kiwi OS version will not... or at least not with the Grove Cookbook stuff
