PK232SAT.3 is the correct trace with an ohm meter. Cut with care (with a sharp X-acto knife) so adjacent traces are not touched. 3. Mount a SPDT switch on the front panel where it will not interfere with other components (like near the upper left corner by the AEA logo). 4. Connect the center of this switch to the inner pin of JP4 or the trace that goes to it (which was cut to disconnect it from U15 pin 6). 5. Connect the switch contact which will be "RXR OFF" to U15 pin 6. 6. Connect the switch contact which will be "RXR ON" to U15 pin 2. As you have the PK-232 apart, this is a good time to sand off all the paint where the two cabinet shells mate and screws fasten to improve RFI shielding. Star washers under the cabinet screws will also improve grounding. This reduced PK-232 RFI into my receiver. Toroids on all cables connected to your receiver may also help reduce RFI. Now you can copy Uo-11 with the same settings as for Uo-9, but with your new hardware RXR switch "ON". Be sure to return it to "OFF" when you want to return to normal operation, as this switch is on line for all modes when the PK-232's internal modem is used.
