Found another ZFL-2000 amp in the lab stock - but this one is tagged as “BAD”. Will retest and if actually defective, will set aside for disassembly during next snow day. Curious to see if there is a part number / label on the back side of that 12-pin circular Mod-Amp case. #rfamplifier #smokeletout

@ai6yr Plating on battery springs is overrated. First thing to go (flake off or dissolve). Not at all surprised to see leakage with that brand. Had a set of Costco Kirkland cells leak (and really destroy) a LED flashlight recently. First time for that brand to leak badly at this end - so far […]

@mcdanlj Congrats! Onward and upward!

@ai6yr You know you’re having #hamradio fun when you are replacing/repairing coiled-cord microphone connectors! Tiny-tiny thin wires, often with melt-back insulation. Bravo if it goes back together and works! 73

Completed a few tests on the 2.4 GHz RF Equipment (RFE) components for the single-band Pluto transceivers. TLDR: All looks good and ready to continue evaluating controller software. Details at the qsl.net blog. #hamradio #sdr

@mcdanlj Thank you for the informative summary. Very helpful! Considering options now for future POTA activities here in EN52. Thanks & 73

@EverydayMoggie @ai6yr A soldering iron will tighten up the loose ends to prevent fraying. Don’t use your best tip! 😎

@wa7iut Nice! Very quiet acoustics too! Super useful RF Engineering tool!

(don't believe in premonitions, but whatever my brain picked up... it was cheaper to buy some disasters supplies, i.e. beans, rice, olive oil, N95 masks, gloves that doing anything else, and that was it).

Here is the system drawing showing the local laptop PC with headset and the remote computer & RF equipment group (Raspberry Pi 5, Pluto SDR, and transmit/receive amplifiers and filters leading to the antenna). Ideally, the remote equipment is located VERY […]

The 3/8-24 antenna ground-isolator/connector test box is completed. This simply connects or disconnects the lower ground stake connection to the upper counterpoise / coax-feed and vertical whip assembly. It’s easy to have the ground stake connected with the […]
