RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Design a USB RF Device - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

Hello, I am not an electrician or even well versed
in circuitry but I do have an idea that I want to employ. I am currently
setting off professional fireworks using a RF transmitter and receiver.
Instead of using the handheld transmitter I want to build a usb device
that mimics the handheld. In this way I can use the computer to send
a signal to the receiver to set off the fireworks thereby giving the
process much more accuracy and the ability to coordinate the fireworks
with music. Any help with this would be most appreciated. Thank you.

Using the USB port sounds rather
Instead you could either design a simple parallel port
interface to a UHF 433 MHz transmitter more easily, or there are ready-made
solutions available on the market that do it this way. A source in the
UK is quasar electronics, but they are available world-wide. The main
application is to extend peripheral device range from several feet to
hundreds of meters if desired.
Alternatively, the same sources probably
have USB interfaces too. I never checked for those.
