PPB is parts per BILLION, so you'll need to multiple the PPM by 1000.
Many thanks !
Last year i had problems with this settings, and try a lot.
So frustrated that i stopped working with spyserver.
Now running about 3 á 4 weeks spyserver with a good value.
I have to say this.

Troubleshooting Help • Re: Telnet and the Net Remote Plugin

Hi,
You can also try putty 32/64 on a windows/linux machine or even on the Raspberry Pi.
This is a list of commands that i tested years a go. I hope the commands are all te same as before...
Tested also with arduino and a dial knob to change frequency. It was too fast, SDR# gets frozen.
So I've stopped working with this plugin, and I'm not a programmer.

CODE:

Show me your diy LNA housing

Hi folks. I think my LNA is arriving today or tomorrow. I want to see how you made the housing for your LNA.

Best antenna type for broadcasting with a Rpi?

So, I want to try broadcasting a message to my friend who's a couple blocks away using FM with Rpitx (with a FM filter of course, and I made sure I'm not breaking any laws). I'm building a discone antenna now for receiving, but I'm not sure that's the type I want for broadcasting. A simple whip antenna would be the easiest, but if there's something better I'd like to know. Thanks!

NOAA Automation?

Is there anyway to automate the decoding of NOAA images and putting them on a local web server? Planning on using a RPI3 etc. Thanks

Comment on Leif Compares the Airspy HF+ with the Airspy+Spyverter Combo by Ken C

what i have set up is, an almost new Dell with AMD Ryzen 7, win 10 did a clean install from an ISO from microsoft because the OEM install was cluttered with third party software, and dual booting with Linux, i notice Linux with GQRX built from a the lastest github sources runs airspyhf better and cleaner than windows 10 with hdsdr, sdr# does better than hdsdr with an extio.dll, and sdrconsole_v3 does better than hdsdr too, but by far my favorite is GQRX on Linux, the only peeve with airspyhf is the antenna sma jack is soldiered directly to the board, they should have used a short jumper wire like the SDRPlay has done, then when somebody has to tighten the nut on the antenna jack it does not break the soldier on the board (i had top open my airspyhf and resolder it to the board after tightening it) other than that the airspyhf is a nice little sdr, i love the heavy steel case it comes in

so anyone reading this take extra care when tightening the nuts on the antenna jack otherwise you will break the solder connection and have to open it and resolder it,

Very poor reception with my new QFH, where do I start troubleshooting? MIC.
