USB cable recommendation?

Hi; Can anyone tell me which brands of USB cables work best with the RSP1? I have several that were not suitable, because they caused RFI into the RSP through the antenna, which is an outdoor wire with un-un transformer. The one I am currently using is too long, so I need a shorter one. I suspect th...

RSP1 Max input signal?

Hi; I have the SDRPlay RSP1. I have been seeing some EMI on the HF bands, and would like to know whether some of the problem could be the RSP's inability to reject the unwanted signals. The only tunable signal source I have is my RigExpert AA-170 antenna analyzer. It can perform as a rudimentary sig...

Re: Record file size

Thanks. I should have figured that out. Not really paying attention. Too much going on the radio :oops:

Record file size

Hi; I have tried the record feature in SDRUno, and am interested in knowing whether there is a way to reduce the file size. After about 30 mins of recording baseband, I have a total of about 5Gib in several files (each file is a max of about 2Gib). Also, is there a way to change the default folder i...

Re: Centering panadapter display

Strangely, or not, you meed to be zoomed to at least one level before the "vfo" button will work to center your display.

SDRUno RSP1 NB doesn't do much

Hi; I'm running SDRUno 1.1 with SDRPlay RSP1. I am listening on 20m amateur band, mode is USB. Trying to pick out weak signals from the noise, I found that the NB (noise blanker) does very little to nothing. If I set threshold too low, then it cuts out the noise, and the signal, leaving a popping an...

Re: What is "LO Plan Frequency"

Thanks for explaining that. I wish I could shift the LO in my Yaesu FT60 and VX150 when listening to "out of band" services like police/fire, and railroads. Sometimes I get really bad overload from my local police transmitter, which causes their signal to desense the receiver, making it ve...

Re: Zero vs Low IF

Thanks guys; I guess the SDRPlay defaults to Zero IF so that you can get the full 10Mhz bw, which seems to be a big selling point. I am finding that I use 2Mhz most of the time. After all, there isn't one HF Amateur band that spans even 2Mhz! Interesting about the LO vs tuned frequency. When I first...

Why so much delay?

Hi; I was listening to a repeater on my Yaesu FT60R, and at the same time listening to the same repeater and its input on SDRPlay RSP1 with SDRUno 1.1. There was about 1/2 seconds delay on the SDR compared to the repeater direct on the Yaesu HT. I tried switching to ASIO drivers, but that didn't cha...

Zero vs Low IF

I had to learn the hard way when to use Zero-IF and when to use Low-IF, during which time I was baffled. I had been listening to the 40m band using the default Zero-IF. At some point I switched to the AM broadcast band, and found that when I tuned to one of my local stations (880Khz), set the filter...
