Subreddit for all things Software Defined Radio (SDR), both hardware and software.
Welcome to Reddit's own amateur (ham) radio club. If you are wondering what Amateur Radio is about, it's basically a two way radio service where licensed operators throughout the world experiment and communicate with each other on frequencies reserved for license holders. All topics relating to the hobby are welcome here, from purchasing and building equipment, to operating techniques and activities, and everything in between.
A subreddit for the low-cost software defined radio (SDR) community. While originally dedicated to the [RTL2832U USB rtl-sdr](http://sdr.osmocom.org/trac/wiki/rtl-sdr) project, relevant content related to general SDR, RF, and similar projects are also welcomed.

r/shortwave — frequently asked
How many members does r/shortwave have?
r/shortwave has 55,254 members as of our most recent crawl on Oct 15. Prowlo re-checks tracked communities on a rolling schedule, so this figure moves rather than sitting frozen at whatever it was when a scraper last ran.
Is r/shortwave growing?
We don't have 30 days of snapshot history for r/shortwave yet, so we're not going to invent a growth number. We've been tracking it since Oct 15; the chart fills in as history accumulates.
How active is r/shortwave?
Around 6.7 posts per day, measured from the newest 100 posts on Reddit, which span 14.8 days. Posting rate matters more than subscriber count when you're deciding where to spend your time — it determines how long your comment stays visible.
When was r/shortwave created?
r/shortwave was founded in May 2011 and is a public — anyone can post community. Age matters: an older community with steady growth has survived Reddit's moderation churn; a young one with a spike may not.
Who posts in r/shortwave?
Of the last 100 posts we sampled, 70% came from distinct accounts; the newest was published Oct 15. A low share means a feed dominated by a handful of accounts (bots, mods, or one prolific poster) rather than a community.
Can I promote my product in r/shortwave?
We don't have a promo-tolerance read for r/shortwave yet. Default to the safe approach: read the sidebar rules, contribute in threads where you gain nothing, and mention your product only when it is the honest answer to someone's question.
How do I monitor r/shortwave for mentions?
Hit Watch on this page. Prowlo starts crawling r/shortwave into your Dataset — every new post indexed and embedded, searchable semantically, queryable by your AI agent over MCP, and able to trigger keyword alerts in Slack. Prowlo is read-only; it never posts on your behalf.
Can my AI agent read r/shortwave's stats?
Yes. Everything on this page is one MCP tool call away: catalog_get_subreddit returns r/shortwave's members, growth, promo tolerance and similar communities as typed JSON — free, no credits. Connect your agent to api.prowlo.com/mcp and it can vet the community and start watching it in the same conversation.
