LeRoy Miller<p>I can honestly say, I have no idea why I bought 10 of these 433Mhz receivers (HC12?), and 5 of these Transmitters (FS1000A)..... <br />They are OOK/ASK. I found them in a box that has been in storage for years. The thing is I already have a bunch of these modules, and I don&#39;t use them. So I have no idea why I would buy more.</p><p><a href="https://mastodon.radio/tags/Arduino" class="mention hashtag" rel="tag">#<span>Arduino</span></a> <a href="https://mastodon.radio/tags/RXTX" class="mention hashtag" rel="tag">#<span>RXTX</span></a> <a href="https://mastodon.radio/tags/433Mhz" class="mention hashtag" rel="tag">#<span>433Mhz</span></a> <a href="https://mastodon.radio/tags/FS1000A" class="mention hashtag" rel="tag">#<span>FS1000A</span></a> <a href="https://mastodon.radio/tags/HC12" class="mention hashtag" rel="tag">#<span>HC12</span></a> <a href="https://mastodon.radio/tags/OOK" class="mention hashtag" rel="tag">#<span>OOK</span></a> <a href="https://mastodon.radio/tags/ASK" class="mention hashtag" rel="tag">#<span>ASK</span></a></p>
