Modification to the Yaesu FT-736R. G4WFQ 12/1/92. This modification was given to me by Zeno Wahl, G0NJC/VE3LMX (U.O.S) The modification lowers the frequency response to 3 HZ, and gives a far better "eye" by reducing L.F flutter. Proceed thus. Locate "TXPLL UNIT" (Vertical board on Tx unit). Locate R01 (Scrape any paint off. Wet component with FINE solder. Solder 560ohm Resistor on R01 (end nearest to pll board) Solder 47micro fara tantalum in series with 560R. Take (-) negative leg of Cap to Gnd, eg case of Txpll unit. End.
