This assumes you know morse code well enough to verify if the ID is correct
or is the wrong one.   Many times translators in large networks get swapped
around end up sending out the wrong FSK ID.    A true morse decoder would be
better for those who don't understand morse code.

In some models you can verify the ID by looking at a field in the web GUI.
In others the ID is determined by a DIP chip inserted into the unit, these
are harder to verify and keep track of.

When I had an older service monitor, I would check the xltr FSK-ID using SSB
mode. I would zero-beat the carrier of the "space" bit then select the
correct side band (USB vs LSB) to receive the "mark" bit.

You could do the same with any VHF SSB receiver. The FM signal warbles due
to FM transmitter lower frequency tolerance than SSB transmitters. Since you
only need to listen long enough to confirm the ID, such annoyance is short

I asked a few years back and got nothing. I asked how the FCC did it and was

I personally no longer need such a device but I know several guys and gals
who would find it handy.
