At work I had a Fluke 8040(?) that had the LCD tilted up. Worked great, but after a half dozen years we had so many terminals in (and out of) service that I couldn’t spend as much time troubleshooting, and since Lear Siegler was less than a dozen miles away, we just bought enough spares

This continues the updates from my blog of 2017-04-21. Last night was the fifth of May, and I made several important changes to the circuit. I was finding that after adjusting the 8 to 50 pF N150 ceramic variable capacitor, the frequency would drift for hours, then overnight the drift would settle down to a low

From my post to FB groups Well, here’s another circuit that’s doubtful that it works. It looks to me that the 22n capacitor bypasses the amplified RF to ground so the diodes can’t rectify any RF. If there was a 1 to 10k resistor between the diodes and 22n capacitor, then I could be persuaded

I was working on the 27 MHz oscillator for testing the regens, and I thought it would be a good idea to turn the carrier off for a small fraction of a second every 1 or so seconds. So I built a two transistor flasher with a third transistor to invert the pulses. Instead of

I got these today in the mail. Notice the temporary wire I poked into the connector. I ordered some adapters but I haven’t received them yet. I bought a frequency counter with the rubber ducky antenna but it doesn’t have the sensitivity that this cheap one has. I got two of these for $28, free
