Re: External LPF / Attenuation
I've never had to put attenuation on the Hi-z port as I find the range of the RF gain slider is plenty enough. A set of filters is a good idea. I use a LPF to roll off everything above 500KHz when I'm looking for NDB's (200 to 500 KHz) and another LPF which rolls off at 100 KHz when I'm looking for ...

Re: Corruption of SAM SB audio
What's actually happening - ie what does it sound like? I notice from your screenshot that your noise level is high and I can't see the level of the incoming signal as it is hidden behind the SAM box. However I think the SNR is very poor, possibly 3dB? I think under those conditions it would be diff...

Re: SDRuno Software Issue
This sounds like the bug that has the default step for AM set at 100kHz. It's due to be corrected soon, I think. You can select a step of your choice by right clicking in the main frequency display area and selecting from the menu.

Re: RSP1A sample rate
I don't think you can, you have to choose from the values in the menu.

Re: New Member/User from Scotland.
Steven - my HP laptop is an i5 clocked at 2.4 GHz with 4 Gigs of memory. Running my RSP2 with one RX enabled at 2MHz b/w, it hovers around SYS17% and SDR 12% CPU load. I can leave Uno running while I surf the net without problem. Even at 8 MHz bw it seems fine. It sure sounds like something is a bit...

Re: RSP1a and BIAS-T
I think there is an over-current trip which turns off the bias-T if more than 100mA is drawn. From the datasheet: 4.7V /100mA Guaranteed. Note : Bias T has an over current protection circuit. Current in excess of 100mA will cause the bias T voltage to disable. Removal of the overcurrent condition an...

Yes, I believe there is a button in the 'main' window.

Re: New Member/User from Scotland.
Hi again Steven. If it's anything like our recently-bought HP laptop, it will be loaded with all manner of 'helpful' (NOT) applications, some of which will run from start-up. Stuff like performance monitors, virus sweepers and update checkers. A pain in the neck. It's worth disabling these and dragg...

Re: New Member/User from Scotland.
Welcome! Audio hiccups and pausing are normally down to a lack of power in the PC. My old P6200 laptop would get its pants in a knot if I went above about 6 MHz sample rate, but my newer i5 is happy all the way up. Or it could be that there are several background processes running (things like virus...

Re: RSP2PRO vs RSP1a
The most obvious difference is the three selectable antenna inputs on the RSP2. Two SMA types which are best for VHF and the high-z terminal block which is optimised for 0 - 30 MHz. The RSP1a has only one input but the input filters and signal routing has been changed to make it suitable for all fre...
