MIC & Antenna module

[walid1]

If I want to simulate the circuit shown in Fig.FM01 using pspice, and I want to module the mic and putting an ac sig source in its place. what are these values representing a human voice:
1- Peak to peak amplitude
2- Rs - source resistance
3 frequency i think it is between 300 to 3400 Hz i choose 2000Hz

Now to simulate antenna, what parameters should i have, thanks.
Note: Fig.FM01 from:

The antenna would be a 70ohm resistor connected to ground, I've never had any luck simulating these circuits in any simulation software - good luck.
