PDR 3500

This is a page about the PDR-3500 a portable version of the Quantar.

These are cool stations that take the standard Quantar modules. They are able to be powered from AC or 13v DC power, as the internal amplifier is 12v DC powered.

The station backplane is different here in that the PA ID is set using a 4 bit dips witch on the unit. This also adapts the SPECTRA PA module to the Quantar exciter, fooling it into thinking it's a Quantar PA.

Changing Bands

As the unit takes the standard modules, you can easily change bands by moving modules. The issue is the PA is an adapted from the SPECTRA Mobile radios, and uses the same PCB but mounted on a custom heat spreader.
