Metal Case Upgrade for SDRplay RSP1A with Bonus Antenna Set and Carry Case
15 Feb, 2019
Good value for money. Here's how to make it even better.
This is a good product and will help keep out stray RF but there are a couple of things that you can do to make it much better. The whole case is painted and as such the 4 pieces that it comprises of do not make good electrical contact. I suggest that if you buy one of these to do the following.
Firstly remove the paint from both ends of the case using sandpaper so that there is a good electrical contact between all parts of the case.
Secondly solder a piece of braid between the top of the USB socket and the nut that holds the earth post in place. This made a terrific difference. Before doing these modifications FM broadcast stations could be clearly heard with no antenna connected. After the modifications there were no detectable signals anywhere in the FM broadcast band so I would call that a good result!
