[TenTec] location of r23 on final board in Jupiter

[Bob McGraw K4TAX]

You can measure the driver bias at the Emitter of Q5, or at pin #2 of 
U1a, or at the junction of L1 and L2.     I'd say about 0.7 volts is 
about correct.   Ideally you would do a 2 tone IMD test to determine the 
best value.   But for most devices, 0.7 volts is good enough.

Good luck in getting the radio going.
