Legendary Drake Performance
Puts the World in Your Hands |
The Drake R-8B. The premier world band communications receiver that delivers a more
complete perspective on the world.
It’s one thing to listen to international broadcasts, but quite another to pull in
the far corners of the globe, with the reception necessary to be in the action via
short-wave commercial broadcast, ham bands, RTTY or CW. But you want to be there
experiencing the world with clarity and definition.
With sophisticated features like selectable sideband, synchronous AM detection, five
built-in filters, pass band offset, and 1000 programmable memories, the R8B delivers the
world to you. Experts have praised the R8 series for its unsurpassed clarity, audio
quality, versatility and range. And hobbyists marvel at the performance and ease of use.
The R8B has built upon this fine tradition to bring the world to you with performance that
is legendary.
And now you can experience the legendary performance of the Drake R8B risk free. Drake
