Hello everyone,

Very new at this with the modest aim of getting an FM receiver up but I
have two questions that are simple enough.

1) Considering that we started with the basic Rx and a wire, we were
able to hear FM 98.7. This was expected but it is a little sup rising
that we can hear this exactly at 98.7 when we punch that into the GUI
for the FM receiver. My understanding is that this signal should have
aliased to < 32MHz and heard there.  Why is it that we can hear this
signal at exactly 98.7 with a wire?

2) Replacing the Basic Rx with a TV RX we purchased,we can definitely
hear bunch of FM signals.  Perhaps this is due to the fact that we dont
have the right antenna for TV RX but all the voices are high pitched
with the TV RX(remember the chipmunks).  What is the cause for that?

Thanks in advance for all your input.
