WebTo switch the QSK-5 to transmit, the T/R input must be grounded or brought "Low". The 1N4007 diode connected to the T/R input protects transistor Q5 is case the T/R input is accidently connected to a positive voltage, rather than being brought to ground. When the T/R input D is open, current flows into the base of transistor Q5 turning it on.
