Occasionally it hits me that normal houses don't just randomly have test gear lying around the kitchen.

One easy tweak to the Penntek TR-45L I’m going to try is aligning the notch knob so that your own side tone is notched out when the knob is vertical. Left is as-shipped, right is modified.

Looks like the Penntek is 5 Hz low (I haven’t let it warm up)

Measuring the TX power of the Penntek TR-45L. At minimum, 36 mV into 50 Ω, or -16 dBm. And a smidge below 8 V when the rig indicates 1 W, which checks out.

Should actually be closer to 7 V… maybe something is off a bit

Just barely able to copy slow CW on air now. In this case only realized I had copied valid CW after reviewing what I wrote down. :)

My latest video is a short review of the @peakatlas DCA Pro, Model DCA75, with brief comparisons to common low-cost testers and a traditional curve tracer: youtu.be/cWqeyn17Vac
