RFX-85

Download Manual

The Powerband RFX-85

The RFX85 is replacing the RFX75. Mechanically, the RFX85 features a new aluminum
heatsink design with thicker ns for more heat dissipation and greater performance. The new
heatsink is fan-ready and supports mounting of either one centered fan or two side-by-side fans.
Electrically, the RFX85 features a fully regulated bias circuit with adjustable control pots for both the
ERF2030 driver stage and ERF7530 nal stage. The addition of adjustable fully regulated bias greatly
improves SSB performance and allows for perfect uning to almost any radio circuit.
The RFX85 installs the same as the RFX75, so no need to learn something new!

    This is a complicated modification and should not be done by an amateur.
You should probably leave the installation and alignment to a proven technician.

The item most overlooked when ordering a custom radio is the microphone.  Your new tuned radio will NOT
sound great  with a stock mic on it  If your CB is more than a tool for work, you NEED to upgrade your microphone. 
My personal favorites are the Astatic 636L and RD104E.

If you place an order from outside the continental USA, we will calculate your actual shipping and send you a PayPal payment request.  We do NOT export Antennas or Base station radios.
