Re: Newbie : listening 3Khz to 148 Khz with upconverter ?

Thank you all. @radiolistener "And connect antenna into "line-in" jack of your sound card." As simple as that ? I think you probably want to use "mic in" if available since line level is around 1V, and I don't think you'll get your LW signal high enough for good quality with "line-in" without an ad...

Re: KerberosSDR Developments in 2020

I know that very well; however, between the Kerberos' hub and the host, 4 devices have to share the same USB 2.0 bandwidth, and I think speed and latency could be improved with USB 3.0 link in there. It may not apply to RTL-SDRs, but when I tested the speed of several USB 2.0 storage devices with US...

Re: More fake units sold on Ebay

Good luck with your dispute, though I would look into the cost of return shipping first. There are a few things that you may not want to buy from China such as SD cards, USB flash drives, and rtl-sdr blog v3 software defined radios. Here are a few fakes I could find -- some not even try to look like...

Re: KerberosSDR Developments in 2020

Would it be possible to replace the built in USB 2.0 hub with a USB 3.0 or better hub? And preferably with a full size USB connector, not one of those micro thingies.

Re: Airspy HF+ Discovery

As per support, they were apparently out of stock, but I just got an email with a tracking number a short time ago.
So it's probably 10 - 20 days until I receive it.

I will order one.
I ordered one Thursday night from itead.cc, but no order confirmation or any kind of feedback until I sent them an email a few minutes ago, asking about my order. Hopefully this gets my order moving.

Re: time stamp signal appearing possible?

Thank you so much aurgathor for replying! I guess I can program enough when I find a hello world example. Because in this case we don;t have any demodulation (only power in a channel) it must be feasible. I looked around a lot to see if there are any any up-to-date examples for Win10 and RTL but I ...

Re: Airspy HF+ Discovery

I may have been wrong in the above post -- I'm currently reading the Discovery's specs, and under both HF tuner and VHF tuner they prominently mention "high linearity LNA" -- however, without looking at the PCB or schematics (and the latter is most certainly not public) it's hard to tell what those ...

Re: Airspy HF+ Discovery

I guessed that. Does the Airspy HF+ Discovery have an internal Amp? The RF chip should have an RF amplifier portion inside, (an equivalent of a dual-gate MOSFET commonly found in some analog tuners) but if you are thinking of a separate LNA on the input -- I do not know. My guess is no -- the RF fr...

Re: FM antenna

In the past such Yagi Antenna was used in Europe: Most Yagis (retail) are highly directional and I specifically want an omnidirectional antenna since there are FM towers in all 4 quadrants. An antenna for (US) Ch6 should work fine on FM, but TV antennas in general are directional or highly directio...
