It's a different subject today. Looking toward some way of determining the bandwidth of RF filters and amplifiers I have recently aquired a 'tinySA Ultra' spectrum analyzer - see link -
https://www.tinysa.org/wiki/
This unit looked as good as I could reasonably get for my purposes, as I do not have the space for larger bench equipment and obviously bench devices tend to be expensive as well.
Currently I have only had a look around the menu's and watched a few of the YouTube videos. One of these was for the test of sensitivity of a comms receiver. This proved opportune as I have recently noticed that mine has seemed a bit down. On test I rapidly determined that there was a problem and even more quickly found the local/DX switch had dirty contacts. All is now well. The only other thing I have tried is using it's aerial and observing the signals of the local FM radio transmissions.
Although I am progressing and planning future use I thought that it may be good to ask if anyone has had any experience of these and opinions / personal opinions on their use.
