    I like how you explain the different building blocks on the schematic and how they do their specific task. I have basic understanding of electronics but thanks to you, it all makes more sense.

    Just keep in mind the loading that a 1x scope probe will place on your circuit:
    - When the probe is connected to a 1Mohm scope input, the 1x probe will add approx 100pF capacitive loading.
    - When the probe is connected to a 50ohm input (like a SA input), the probe basically looks like 50 ohm load (with a little extra loss)
    You'll need to assess whether your circuit can tolerate the loading, and that the loading won't throw off the tuning.

      you will enjoy my next video. I knew people would comment on my scope probe use. I guess you fell in my trap. anyway I shot tomorrows video weeks ago so it is not pointed at you.

      @@IMSAIGuy Yep, you 'hooked" me... Proper probing is a pet-peeve of mine...

    Don’t ya love how those Whirlpool dryers know CW

    Great explanation. You should reduce input to 0.06uV and a carrier (CW) can still be detectable. Receive is razor sharp. Maybe too sharp but it will pull that DX out of the noise. 73 - Rick - Midway Electronics.

    I'm still not comfortable with dBm. I am more comfortable with dB being a dimensionless logarithmic ratio.
    You have me looking at those Spectrum Analyzers on ebay, but I still want a NanoVNA first.

      baby steps. start with dBc then once you are comfortable with that, imagine your carrier is always 1mW.

      Maybe my video on dBm, dBc, etc. will help: ruclips.net/video/1mulRI-EZ80/видео.html

    The "how too" is beginning to focus for me. More probing with the SA, please.??
