Thanks for the video. Unfortunately I still don't know how to interpret sensitivity specs on a UHF/VHF radio. If one radio has a rating of 0.25μV at 12dB SINAD, and the other has a rating of 0.35μV at 12dB SINAD, which is the better receiver? Thanks for any info.
Sorry, I obviously did not explain this well enough - the lower the value in microvolts for the given signal to noise ratio or SINAD, the more sensitive is the receiver. If one receiver has a SINAD or 12dB at 1 microvolt and another one gives the 12dB SINAD for 0.1 microvolts, then the receiver with the 0.1microvolt figure can receive smaller signals for the same noise and distortion level and therefore t is the more sensitive. I hope this helps.
Well explained and useful. Are there levels of SINAD which are genereally regarded as a threshold or yardstick measurements of a sensitive FM receiver?
I think the best way to look at that is to check out some specific radios in a group. Normally for VHF / UHF amateur radio handhelds, I would expect to see figures of better than 0.2 microvolts for 12 dB SINAD. But best to check a number of radios in the sector you are looking at and check the performance levels.

@@ElectronicsNotes Awesome! Thanks. Makes sense now.

@@ElectronicsNotes Thanks for taking the time to reply. It was most helpful and I appreciated it.
@@acestudioscouk-Ace-G0ACE Pleassd to be able to help.
@@ElectronicsNotes Better, meaning higher than .2 microvolts, or lower?
Nice!
Glad you liked it.
