Bummer, that is not right, of course.
The grid current meter must be placed in between the connection to the RF bypass capacitor at the cold end of the 22K grid bias resistor, and down to the 'T' connection with the brances off to the PTT switch and the second 22K resistor. If placed anywhere else, it will either be subjected to RF currents, or it will also measure the 'dummy' current supplied by the bias voltage source and through the secondary 22K resistor.
