Hello to all, Vectronics PM-30 SWR/Power Meter. I got problems with my PM-30. I go not have the Owner's Manual. Tried to download the Manual, but the schematic and part list are = missing, I have sent two e-mails to Vectronics but no response. The part list and schematic are needed (need the value of the resistors and diodes on the coupler board). Can anyone help? 73 Gil, LA1NG
