Re: Proposed upgrades to RSP1 no cancelled ??

Hm, I would say most of the wishes for the RSP 1 have been recognized and the result is the RSP2. Only thing I don't like with the RSP2 is the high impedance antenna input for VLF and LF. I am using an active antenna there which has a 50 Ohms output. So the recent buyers of the RSP1 have funded the...

Re: Learning to use SDRplay for Inmarsat

That's good, so you have a big margin in your link budget, i wonder which signal level would catch your L-Band antenna without obstacles.

Could you post a photo ?

Have you conducted any Aero channels decoding with Jaero ?

If positive, what ENOB's values you saw ?

Wide band spectrum analyzer / scanner

I'm used to tune my RF filters with the help of SDRRTL scanner stand alone program (windows version), a generic RT820T USB dongle and a RF wide band noise generator, so i was wondering if exist, or is under development, an equivalent application for SDRplay. The 12bit ADC sampling system would give ...

Re: Learning to use SDRplay for Inmarsat

but I noticed that the signals were always several dB stronger if I beamed through the brick wall instead of the window. For sure your is not a reinforced concrete house, otherwise you should get ZERO signal. Are the walls made by brick & mortar or is wooden construction ? How may dB you gain p...

Re: Dimensions of new case

I conducted some rough RF "leakage-in" test closing the SDRplay input with a 50ohm tap, in this condition on my bench i receive residual FM brodacast and 900Mhz GSM signals, the latter with quite strong amplitude. Of course things change a lot moving the device. Shielding externally the SD...

Re: Frequency Error?

"@IW2NYX: WWVH should be at 10.000 MHz, not 9.996 MHz. You'd better adjust your Frequency Trim :-)" Dear jschall, that screenshot is about the time signal of Moscow Institute of Metrology for Time and Space, that transmits on following freqs : 4996 Khz 9996 Khz 14996 Khz http://www.vniift...

Re: FM "ghost" signals on UHF

@mbott : you need a more performant notch filter, the one you pointed out has a min notch depth of "only" 25dB, mine has a min depth of 40dB / max depth of 60dB (tested on rf network) and does not fully solve the problem, see my "review" on this section of community forum. In add...

Re: Frequency Error?

1500Hz seems a lot, i suggest to switch on the carrier of another station, ie wwvh NIST (http://www.nist.gov/pml/div688/grp40/wwvh.cfm)

With -0.7ppm LO trim my SDRplay is frequency "spot on" on most reference stations.

A mixed bag, something good, something bad !

Hi to all, i'm a fresh new SDRplay's owner, two days ago i got this toy with a lighting fast shipping service (thanks for that) and i put it "under load" to check its performance. I have to say in advance that i'm quite experienced SDRs user, i started to play with them lot of years ago (w...
