mc1822d Posted January 2, 2020 Report Share Posted January 2, 2020 How much bandwidth is recommended for working on ham & shortwave radios with frequencies up to 30Mhz? Can I get away with 70Mhz? 100Mhz? I am only interested in new digital scopes and my budget tops out at $300. Quote Link to comment Share on other sites More sharing options...

HarryA Posted January 3, 2020 Report Share Posted January 3, 2020 There is an old rule that you need at least 2 times the frequency that you wish to view. There is a publication by the ARRL "Oscilloscopes for Radio Amateurs". On Amazon.com is near 20$ used or about 10$ for the kindle version that maybe helpful. The kindle version can be viewed via their free PC app. Also there are videos on YouTube on choosing an oscilloscopes. I have a Hantek DSO5202P it was far more functionality then I need. I did have to replace the display after about three years but they are not expensive. 37 minutes ago, mc1822d said: 40 views and no advice? 😭 The problem I have is that I answer so many questions that I like to give others a chance to answer some. But that is not always helpful I know. 🤨 Quote Link to comment Share on other sites More sharing options...
