You want to calibrate at the highest frequency possible as the calibration applies as a proportion to the frequency AND the front end has a step size that may or may not affect your ability to get a

If you are running in a spyverter environment you absolutely do not want to mess with AirSpy's LO. It will give you wrong results. Look for the "shift" setting. That will "sort of" correct for

Well, I think airspycalibrate.exe is the tool, but I don't have the instructions. As I have RF generators driven by a GPSDO I can do it and in fact I did it a long time ago. I'll appreciate

Many thanks for your replies. I found the error over a wide range of frequencies that were of centre especially when using decimation. I can live with it not being precise to 1Hz or so but it was a

I'm setting up my Nooelect Smartee dongle with a new Raspberry Pi 4 (2GB) after having used it on a windows machine with SDR#. Everything seemed to go smooth.. i can see the dongle and run everything

Here is a youtube video sone people may find interesting about the high voltage effects of falling snow on radio. https://youtu.be/-_MsOjQEC3k

Thank you for the instructions. I had calibrated it some time ago, my unit is from the first batch,  but I forgot the procedure. I'm well equipped with frequency standards (Rubidium and GPSDO) to do

I use David J Taylor's excellent FastWXTrack program with his DDR Tracker plugin for SDR#. FastWXTrack is especially suited to tracking LEO sats as it updates the frequency in SDR# around 20 times per

From: Airspy US via Groups.Io Is anyone using their Airspy to track non-geostationary satellites? If so, what SDR# plugin are you using to correct the Doppler

SDR# is not used for calibration of the Airspy R2. Use the stand-alone program AirspyCalibrate.exe (in the Windows SW package DL) to calibrate the R2 (or Mini). Make sure you understand how to use it

This ppm box is meant for calibrating the upconverter LO, hence it is grayed out when the Spyverter is not selected. I don't remember how to calibrate the AirSpy LO, I thought that I

At what frequency? At 1.75 GHz that would be damn good "you can't do better without a GPS lock." At 175 MHz it 2 ppm. You CAN fix it. Now, how are you figuring it is 350 Hz out? Are you presuming

My R2 is 350Hz out and I am trying to understand how i could re-calibrate it preferably with an off air signal as mentioned on here. 1.If i use sdr# and tune to a signal the ppm is greyed out unless
