Hi Simon
I have the tx section working great, a local station can hear my carrier
very strong, but the modulation is very distorted. I am using an electret
microphone, I may try a different mic. I will keep you posted if you send
your email. Please let me know if you encounter the same problems.
Hope to hear from you soon.
I would be very greatful if anyone has any ideas on how to test the mic amp
circuit.

I have built the poppet top band am transmitter from the sprat cd. It is
transmitting the am carrier ok, but there is no modulation.
Can anyone suggest how I can test the microphone amplifier circuit.
