Modifications

Some "simple" improvement modifications for President Lincoln

Improving RX Audio :

# Add a 4.7 uF/16 V Electr.Capacitor across (in parallel) with R152 (= 560 Ohm)

RogerBeep Modifications :

# Locate R 96 (= 2.7 M Ohm) replace with 100 K Ohm/ 1/8 watt resistor

This increases the amplitude of the beep

Change Length :

# Replace C 110 (= 10 uF/16 V) with capacitor at least 50 V with MORE- or LESS capacitance

to lengthen- or shorten the beep

(Components located on left side of IC 104)
