Subreddit rules check
r/sdr
Can you promote here?
Promotion is allowed only with moderator permission (or inside designated threads). A short, honest modmail before posting costs two minutes and functions as a safe-conduct pass; skipping it is the most common avoidable removal.
Links
No explicit link policy. Default to no URL: link-plus-young-account is one of the most common automated removal patterns on Reddit.
What this community rewards
Dominant post formats: question, discussion, guide
Headline: concise technical summary (e.g., “Help with IQ imbalance on RTL-SDR”). Use first person for troubleshooting/project logs, third person for tutorials. Typical post = short title + detailed body with hardware/software versions, configs, screenshots/logs. Tone: technical and practical. Upvoted: reproducible experiments, clear how-tos, troubleshooting steps. Removed: off-topic, low-effort, or blatantly promotional posts.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked July 2026. Rules change and moderators have the final say: verify at r/sdr's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
