I2C0 is used for SI5351C I2C1 is used for R820T2 (ref: https://github.com/airspy/airspyone_firmware/blob/master/airspy_m0/airspy_m0.c#L155 ) And guess what, on the LPC4370TFBGA100 used in the Airspy R

GPIO6[28] at symbol PD_14 does not on the TFBGA100 package used in the Airspy R2, it is only available on the LBGA256 package on pin R13 and that chip is not used. GPIO5[3] at symbol P2_3 is available

Hi folks, I've been looking at if it is possible to use an external signal (e.g. 1PPS) to trigger data capture on an airspy R2. This question has been asked before, but there isn't a definitive answer

#airspyr2

The experience will build up with experimentation and good readings. I'm glad this approach helped so far.

Thank you! I managed to modify the original firmware and get 3 syncronized 10 MHz outputs from the ports following your suggestions. It wasnt easy because im very unexperienced working with github. Im

I'm not sure where this request fits. The code is disclosed for the adventurous programmers who already know some programming but didn't necessarily participate in the design phases of the device. Eve

Hello! Can someone please help me creating a firmware for Airspy R2 that has CLK4-6 enabled with 10 MHz output? GPS 10 MHz reference in Regards Simon

#airspyr2 #firmware #request

That is one of the variables I mentioned. Known source with known measurement device is the way to do it. {o.o}

#sdrsharp #airspyr2

I would more trust a gain plot than a noise floor plot. The noise floor plot has too many variables contributing to it. If I could I'd figure out how to build a digital 1, 2, 4, 8, 16 five control bit

#sdrsharp #airspyr2

FYI, this the "noise floor" measured from SDR# manually with GAIN=14 and Linearity mode. The 390 MHz gap is the antenna combiner and the 87-118 MHz gap as the CCIR -20dB attenuator Regards, Ondrej EDI

#sdrsharp #airspyr2

Hello jdow, thank you for many useful comments. I was thinking the same way before asking about the plugin. Obviously, the best solution would be a "30-500MHz frequency dependent attenuator" which is

#sdrsharp #airspyr2

Are you allergic to or religiously opposed to an external switched resistor attenuator that is controllable via a GPIO port? Really, that is probably the cheapest and easiest thing you could implement

#sdrsharp #airspyr2

That brings up other potentials for your issue, presuming you are doing what is needed to make the dB display in SDRSharp mean anything other than how far a given signal is from overloading the A/D co

#sdrsharp #airspyr2

Ok, I hope prog will come with the API soon, I would appreciate any sollution. Regards, Ondrej

#sdrsharp #airspyr2

sorry should have read jdow. My android auto corrected it to the wrong thing.

#sdrsharp #airspyr2

Also, as JDownloader mentioned, as was correct as well, there is a problem if bands overlap and I let you set different gain settings. I am waiting to see what prog comes up with in the API before con

#sdrsharp #airspyr2

The problem is, that both AGC and noise reduction influence IF or AF signal, which might lead to noise reduction as you mention. However, this doesn't solve the receiver front end overload with strong

#sdrsharp #airspyr2

Instead of the more complicated gain settings that are specific to the radio hardware, would it work to just be able to specify different AGC threshold per band? I find that adjusting that value often

#sdrsharp #airspyr2

Hi, regarding my antenna setup - for HF, I use active Wellbrook ALA-1530LN, for VHF the AOR DA-3200 with low noise preamp (23dB,for F=0.7) and for UHF the SIRIO LBN-430GP/N with the same low noise pre

#sdrsharp #airspyr2

prog, jdow, - I will wait for your API before progressing further. Keep me updated please.
