P. G. Warren<p>Anyone who knows me knows I’m slightly obsessed with radio — I’ve been using the sounds of radio in my music since the early ‘90s — so it’s always great to visit BBC Broadcasting House and behold the iconic white lattice radio tower. The tower is more symbolic than functional although apparently it can be used for experimental broadcasts over a short distance.</p><p><a href="https://mastodon.world/tags/radio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>radio</span></a> <a href="https://mastodon.world/tags/broadcasting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>broadcasting</span></a> <a href="https://mastodon.world/tags/antenna" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>antenna</span></a> <a href="https://mastodon.world/tags/transmitter" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>transmitter</span></a> <a href="https://mastodon.world/tags/tower" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>tower</span></a> <a href="https://mastodon.world/tags/mast" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mast</span></a> <a href="https://mastodon.world/tags/frequencies" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>frequencies</span></a> <a href="https://mastodon.world/tags/bbc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>bbc</span></a> <a href="https://mastodon.world/tags/history" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>history</span></a> <a href="https://mastodon.world/tags/electronicmusic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>electronicmusic</span></a></p>
