Re: Newbie With A Question

Hello Henry and welcome to the forum. You'll need a standard USB-A to USB-B lead for the connection from the RSP to your PC and some kind of adapter or adapter lead with an SMA male plug on one end to a female connector which matches your own antenna connector.

Re: In the interest of extending my paltry knowledge base

Although I can't really answer your question, I suspect some of these 'odd effects' that people see are down to perception. Bursts of noise, a strong signal appearing or disappearing etc will affect the AGC and cause the visible spectrum to jump up & down. In Ye Olde Days, we did not have any wa...

Re: RF "surges"

This is probably due to a strong signal (not necessarily showing in the displayed b/w) coming on and off and causing the AGC to act. It may help to read the following document:

Re: Sdrplay rsp1a help

Re: Sdrplay rsp1a signal meter calibration sdruno

Re: Sdrplay rsp1a frequency calibration in uk

Re: SP1 Waterfall flowing up

I think you must have ticked the 'WF reverse' box. To correct it, click the SETT button which is top left on the MAIN SP frame. In the box that appears, you'll find the check-box at the bottom right.
