Re: sdr-radio website layout

Andrew, It is up to Simon but may I just say that many web sites are like this nowadays. You have to look very carefully to get the information and especially the correct links. I guess the site is offered free but at a price of frustration for the users. I hate to say it but unless Simon charges fo...

Re: Addition of TX capability for Hard-rock (softrock with Tx), Multus SDR, QRP2000, Genesis, etc.

Simon, All these are basically the same as the original tuneable Softrock with Si570 frequency generator. Tuning is the same, the QRP2000 LO interfacing is the same. To my simple mind all that is needed is TX audio and the TX enable (PTT). The PTT is included in the original DLL that functions in ot...

Re: IQ recording of entire MW band

Lin,

"Airspy HF Discovery, bandwidth set at 912kHz." says it all.
The Discovery is a low cost high performance SDR - the trade-off is bandwidth.
It is impossible to record more than the sample rate, in fact it is best to use somewhat less than the maximum.

Re: SDR Console v.3.2 32-bit installed, Media-Tech usb RTL dongle installed, recognized, no signal at all

Forget remote controls, no genuine RTL dongle uses one. Even if they did they would not work as the dongle is repurposed with a different driver and software. It seems you do not have a genuine RTL dongle. Avoid fakes. Look here https://www.rtl-sdr.com/rtl-sdr-quick-start-guide/ get a genuine RTL do...

Re: QRPLabs QDX and SDRConsole issues?

I have done further checks and here are my conclusions. I was mistaken, I have not found any tuning faults with the QDX firmware. The QDX has no definition in the Console but a work-round enables it to be used but with certain limits. Select Softrock XTALL, frequency is not relevant. In External Rad...

Re: QRPLabs QDX and SDRConsole issues?

You may try making the IF output 2500 in the panel shown by Joanne. I suspect that will not immediately solve the problem but I found it worked for me and is retained in my final setup. This seems a very strange setting, why does it work? NOTE:- First I had reverted to firmware 1.04.005. It now tune...

Re: QRPLabs QDX and SDRConsole issues?

Could the explanation be that the radio is not actually on the frequency that Console has commanded?

Re: QRPLabs QDX and SDRConsole issues?

I'm no expert on SDR Console, there are different ways to setup SDR programs and sometimes the expected setting is missing. The important thing that should not change is true tuning. If you set tuning to, say, CW then WWV should always be tuned in the centre of the tuning marker at 10MHz. If it is n...

Re: QRPLabs QDX and SDRConsole issues?

OK, I did not realise that Omnirig could be used with the soundcard selected. You have tried reversing the spectrum, I forget what Simon calls it? My QDX now does not tune properly in HDSDR. It certainly has done. I think there may be something changing in the many firmware updates but have not yet ...

Re: QRPLabs QDX and SDRConsole issues?

I've not waded through all the posts, just tried a QDX with Console. I see no way to use it except as a soundcard Softrock, Xtal, fixed frequency. Set it to IQ mode, might as well keep the QDX terminal open to tune it. Select it in Definitions, set the LO (tuning centre) with the terminal. Set the c...
