  • description: In this video, we'll see how to use a Chinese OCXO to improve the frequency readings of a classic Promax frequency counter. By the way, an important point. After I mentioned that a jumper was missing, Jordi told me he had already installed some jumpers to make the change. I must have been having a bit of a scattering day; with the schematic in hand, I didn't even notice. So, even though my modification is correct, it's worth noting that Jordi had already set it up with jumpers, and I didn't see it. That's what happens when you're blindfolded, focused on the schematic and not seeing what you need to see. TinyGTC purchase link: https://www.astroradio.com/p/tinygtc-...
