Re: SDRunoExtIO no longer starts

Please, can you tell me where to find the old dll or the 1.11 version of SDRUNO Hello Gerard, I re-installed version 1.11, made a copy of all the files in the installation directory and the installed 1.12 again. Then I copied the WRPnfdc.dll from the old installation. But I have no clue if the new ...

Re: SAQ Christmas Transmission with RSP1

You also have these strange signals around 16 kHz and 18 kHz, Wolfgang. I have already suspected toys from my neighbours. But they seem to be "real" as you have them, too. That on 18 kHz seems to be weaker at your location. Maybe there are similar electronics in households near you. Don't ...

Re: High noise floor on RSP2??

If I understood it right the noise level rises when any kind of antenna is connected: Bonito MiniWhip or simple random wire. Then I should say the noise level in and around your house is high. a) Are the antennas far away enough from PCs and monitors? b) Does the receiver have a good ground connecti...

Re: SDRunoExtIO no longer starts

After several trials and errors I found out the follwowing: SDRuno 1.12 copies a WRPnfdc.dll dated 02/12/2016 13:46. SDRunoExtIO does NOT start with this dll. SDRuno uses a WRPnfdc.dll dated 24/10/2016 18:33. SDRunoExtIO starts OK with this dll. When I copy this old dll to the new 1.12 installation ...

SDRunoExtIO no longer starts

After installing SDRuno 1.12 I cannot start SDRunoExtIO any more. The programme terminates before anything is shown.
No problem when I go back to 1.11.
Has anyone got a similar problem? What could I have messed up?

Re: Antenna Referred Power Measurement.

To David, to avoid being off topic too much I try a short answer: In Europe the powerline modems (PLT, PLC, dLAN, powerLAN etc.) have been generously allowed at high noise levels due to intensive "work" of the industry lobbyists at the European Parliament, using up to 105 dBµV broadband po...

Re: Continuing Difficulties trying to run SDRUno with HRD

HDSDR and HRD communicate with each other: HDSDR has a built in customized DDE data exchange interface which is understood by HRD and vice versa. You do not need Omnirig for this at all. HRD controls the FT-857 through COM port 5 and HRD controls HDSDR by DDE (and vice versa). SDRuno does not have t...

Re: Antenna Referred Power Measurement.

Well David, there are certainly "better" SDRs with higher direct sampling rates and so on, but I have given up to look for new SDR receivers. The ones I own (Perseus, G33DDC, Anan Angelia, apart from the toys like Funcube, RSP1 or RTL dongles) were expensive enough and it makes no sense fo...

Re: Antenna Referred Power Measurement.

dBm is a power measurement unit (power in relation to 1 milliwatt). In radios the power normally is calculated from the voltage on the 50 Ohms antenna input. Maybe the "creator" of this expression wanted to express all this in one term. But I also think the expression is not very meaningfu...
