nostr:npub1srpkt7pgfhpzw4e8tpsn2pu6csumkyp8n0r03788lykz9hfszu6ssfgqr5 chokes need to be as close ...
@e7b4518c How close is close enough? I put them right at the converter’s output, so maybe 30cm of total cabling away 🤔
So I tried multiple chokes to remove the noise from this DC-DC buck-boost converter, but nothing helped. I still get S9 noise at multiples of the internal PWM frequency (12V Pb battery for testing). Do I need a large capacitor? 🤔 #HamRadio https://mastodon.radio/system/media_attachments/files/111/023/930/473/780/832/original/93e05f1b3eb4038a.jpeg https://mastodon.radio/system/media_attachments/files/111/023/930/551/760/313/original/77c8ba096f038bd3.jpeg
