Thanks Phil, I have made some other small/simple improvements to other antennas. One was adding an extra square plate Reflector to a 15 Element yagi for L-Band Aero signals. Which in turn gave an extra 6dbi (One S point) increase in signal strength. Hi Most Yagi design have only a single reflector....

Hi I too think that it totally depends of what you want to do with the RSP and the software you intend to run. Receiving NDB and DVBT2 HEVC signals have very little in common. Neglected important features of the computer used are: It's power consumption. It's EMC performance. Performance of it's USB...

Those multi turn loops have a drawback: parasitic capacitance.
It is very hard to get a decent tuning range with current variable capacitors.

Only gigabit Ethernet is better than USB2 and the difference is not very big.
And if you have to use POE it gets complicated.

I had this problem with windows 7 and many audio/video related software's. It is not related to SDRuno I tried a lot of tips from various sources with no effect. It seems that the problem mysteriously vanished and I don't know if it was due to an update from Microsoft or the installation of a softwa...

PC monitors or their cables can also produce interference A trick is to start a recording then switch off and disconnect everything from your PC : keyboard, mouse, monitor,speakers , etc Then play back the recording. Of course for a laptop you are limited :) I also found that sometimes interference ...

This is a complex question there is no simple answer. It depends : On the transmitting power used On the directional properties of both antennas On the polarisation of the antennas On the presence of filters in front of the receiver to reduce the signal of the transmitter If you want to use both at ...

On many DVBT dongles the diodes are directly connected to the RF input
So any DC on the coaxial kills them.
Bad design a small capacitor is needed.

Hi 10MHz span is useful to search visually a wide band for activity but ,except for DVBT and DAB, it is always better to limit the span as much as possible when actually demodulating a particular signal. I have found that 1.5Mhz has 2 side notches that can be very useful to prevent overload by local...

I have it working with the help of a test file. But so far, no live reception.
Thanks!

Hi
As far as i know there are very few.
The best way is to look/ask here:
