Wow tube tester. Haven’t seen one of those in ages. Used to be everywhere.
Software uses hardware. If you are talking about sound card scope, then sound chip digitizes the incoming signal and that is what software shows to you. However! Remember that sound chip has a sampling rate that is designed for human speech (or reproducing human speech), so the maximum sampling rate is 40-48 kHz. The 40-48 kHz sampling rate tells you that this sound chip is designed to sample 20-24 kHz frequencies. Now look ahead a little. You said something about radio. How much of the radio you are thinking about is in 0-24 kHz range?So, does the software scope detect different wave shapes or it just reads the peaks and assumes it's a sine?
Also, is there other gear I might need? I've also heard about logic analyzers?

Yeah I had to buy a Mil Surplus one at a Ham Fest for my old tube transceiver Heathkit HW-101 after that. Now it's buried somewhere out in the garage.The world went to hell when they took the penny scales and tube testers out of the drugstores.
