Yung transistor, us a C945 or 9013. Yung relay mayroon sa Deeco na 6V. maliit lang, I think P25. Yung resistors andyan ang values, pati caps. Yung IC, sabihin mo lang 555, P10 lang ata. Yung diode across the relay, 1n4001 will do. Observe polarity. Yung line sa taas ng pix, yung yun galing receiver mo to the mic of the TX. 10ohms across, 1 k in series. Low impedance kasi yung speaker out mo at malakas sobra for the mic, kaya may 10ohms across at 1k pa in series. Kadalasan ICOM porta lang and RX, so may earphone out yun.
