I have two, one of the PDC-1 from Hi-Res
<http://home.att.net/~hi-res/Kits/PDC-1/pdc-1.html>
and another from K4DPK
<http://home.comcast.net/~k4dpk/pep_adapter.htm>
The PDC-1 is a kit, and the DPK is wired. Each one is $30 delivered. Looking at the boards, the layout is almost identical, which leads me to believe that the design is probably from a manufacturer's application note. I have the PDC in a Bird 43, and the DPK is in a W-4. Both work just fine.
The IC is a low-power, dual op-amp designed to operate from a single power supply, and the circuit is a simple "peak-hold" amplifier.
