Hi all,
Can someone tell me what the bandwidth of the FM filter is? I have
fitted it but I cannot see any information regarding bandwidth.
Thanks

What you say is true, but the conditions expected for Mil-Spec equipment
are not typical for the average hamshack - the wires are not subject to
excessive vibration and flexing and are not handled on a daily basis.

Use the real serial port if you can. They are always more reliable than

Since it is pre-AGC it isn't a constant level output but instead varies
