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

Aligned notch knob

[Mike Fikes @mfikes]

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.

@janetacarr Perhaps of interest is that ClojureScript would tend to achieve the same via the code generation associated with macros (see https://t.co/bcHtjWu6hO), but more recently the compiler has been using intrinsics to ensure optimal JS is generated inline for certain core functions.

Effective notch filter in the Penntek TR-45L https://t.co/Ey8JmhdOww

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

[Mike Fikes @mfikes]

Nice 1 ms attack / decay when keying

[Mike Fikes @mfikes]

Nice CW into 50 Ω load.

[Mike Fikes @mfikes]

Seems to be accurate at 2 W, measuring 10 V.

[Mike Fikes @mfikes]

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.

[Mike Fikes @mfikes]

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

@AlanAtTek You hooked me into this world with the PL-386. I could understand the SSB, but not the other strange noises.

[Mike Fikes @mfikes]

Fun new toy. Called by ⁦@AlanAtTek⁩ W2AEW on it yesterday.

[Mike Fikes @mfikes]

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. :)

Fascinating book about Morse code

[Mike Fikes @mfikes]

Practicing more Morse on back deck with perfect weather

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: https://t.co/XvAzzvkT33

Getting some CW practice in while letting a beta of @joulescope run
