Re: SDRuno MW/FM Broadcast Notch

The RSP2 does not have a HiZ hardware MW rejection filter and the software cannot enable something which does not exist. However there is one in the AntA/B hardware circuit if you need to use this feature. The RSPduo has better Hi-Z front end RF filters, which reduces spurious signals, and a hardwar...

Re: Remote RSP via USB/CAT5

It says in the marketing literature that this cable acts like a hub. SDRplay tech support has posted several times that the RSP needs to plug directly into a USB port in order to work properly. The RSP also works best with isochronous transfer as opposed to the bulk transfer USB mode. This cable mig...

Re: RSPduo and bias-T

Just checked my RSPduo with SDRuno and SDR-Console V3.02. With open circuit to my voltmeter I get 4.7V when I turn on bias-T.

Re: Remote RSP via USB/CAT5

Unfortunately full-speed USB2 compliant adapters will not work because they only run at 12 Mbps.. The RSP devices send data at very high data rates and this requires the USB 2.0 to operate in isochronous high-speed (480 Mbps) mode.

Re: Mac or Windows?

Running the SDR in a virtualised Windoze on the Mac puts enormous strain on the CPU. Feel the case get hot and hear the CPU fan spin and you'll quickly decide you don't want to fry your expensive Mac just for some fun with a radio. Ralf DL9KCG I am surprise you found the VM was putting so much stra...

Re: New, happy user

Tony, The great thing about the RSP is there are several software packages to choose from and you can pick the one you feel comfortable with and does the job you want. A few comments... - SDruno is the only software that accurately measure the signal level at the antenna input. It is accurate to +/-...

Re: Which SDRplay do I buy?

I would suggest that you purchase an RSP1A if you intend to use it mainly as a panadapter with your 991A. You will need an external SDR switch if you want to do this because the 991A does not have an IF output port. There are several manufacturers of SDR switches and if you search on this forum you ...

Re: Mac or Windows?

I would use Windows software because you have a lot of choices: SDRuno, HDSDR and SDR-Console V3. All three are free and very good. You can use the one that has the user interface and features that work for you. I find that I use all three depending on what I want to listen to or record. If you want...

Re: Near field to transmission antenna

You can easily exceed the safe level (+10 dBm) for the front end of your RSP when your transmit and receive antenna are both located on a small residential lot. What you need is an RF limiter or SDR switch. If you search this forum you will find lots of discussions on both of these devices. There ar...
