It appears that you are trying to detect and amplify modulation on your 190MHz signal. What is that speaker-looking thingy that is labeled "200Hz"?
That amplifier will never have the bandwidth to amplify 190MHz. The first stage may act as a detector for any low frequency (audio range) AM that is on an RF input, and the second and third stages will amplify the audio. That emitter follower (the last stage) is very strange. You would be better off replacing the NPN and base resistor with a 50 - 100 ohm resistor.
You have no selectivity, so any frequency RF that shows up on the input will be mixed and/or demodulated. Is there a selective RF preamp, or at least a tuned circuit, in front of this?
We can deal with R and C values later, if there is any point to it. :roll:
