hi,
can you provide us the operating temperature range of your device SparkFun WRL-22957 ?
Thanks
Here is the datasheet. https://www.rtl-sdr.com/wp-content/uploads/2018/02/RTL-SDR-Blog-V3-Datasheet.pdf Operating temp is not mentioned here unfortunately.
Like they said it unfortunately isn’t listed, but I don’t trust many electronics above ~150F or so (some plastics begin to warp around here in my experience, especially if taking an average temp…usually there are hotspots that are higher!)
