I found it at: http://www.wentztech.com/radio/PCR1000/PCR1000.html
I found the link at one of the PCR-1000 Yahoo Group sites. This one has very nice close up pictures. I am not an electronics person, but the procedure mod looks like you have to solder a capacitor between the Q85 point and the coax cable which leads to your external antenna, correct? And the coax foil shielding is connected to the PCR-1000 ground screws. Can someone determine if these same mods also work for the PCR-100?
