[TRLog] CW Keying Circuit Question

[Clive Whelan]

Jack,

<< Does
anyone know if the keying circuit in the manual using a 2N2222A transistor
can key the T4XC safely or do I need a different circuit? >>

As someone else has said invert the phase, and *then* use an MJE340 device,
 very well rated and robust for grid blocking.
