Would a high voltage switching transistor with/without an opto-coupler
circuit not be more reliable ?
The opto-coupler circuit can be tailored for the transceiver's output
and a cheap High Voltage transistor could excite the amplifier.
Just a thought.

Many thanks Frank i'm searching for this kind of circuit, have you a
printable (.jpg, .bmp, .gif, .tif etc.)) version with the complete parts
list?
