President Lincoln
CB/HAM RADIO TRANSCEIVER
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)
