FMP vs. FMPA vs. FMP24

[W4KRR]

Simple question(s):
What's the difference between FMP, FMPA, and FMP24? Does it have to do with whether USB Dongles or an Airspy device is being used?
Second, if I am using FMP (or A or 24) as a stand alone decoder, how do I get it to demodulate AM mode?

FMP=original program
FMP24=replacement with TCP etc
FMPA=Airspy

A quick search on Google gave me:

FMP24 v2.11
Support for AM demodulation has been added.
Use the D key to switch between AM and FM demodulation modes.
Squelch logic has been added.
Use -q1 on the command line to enable squelch.
Press Q to enable/disable squelch.
Squelch sensitivity levels are fixed:
Manual tuning: uses loose squelch / will unmute on weak noisy signals
Scanning: uses tighter squelch / will not unmute on weak signals
New FMP24.ScanList file options:
"AM" or "FM" can be used as the "protocol type" for analog channels.
"BW=<num>" can be used to select a specific RF bandwidth filter. Units are kHz.
"DELAY=<num>" can be used to specify a "wait for a reply" delay period. Units are seconds.
Examples:
118.3 AM BW=12.5 DELAY=2 Miami Tower

FMP: samples RF stream at 1 Msps; use with rtl dongles and older DSD+ versions

FMP24: samples RF stream at 2.4 Msps; use with rtl dongles and newer DSD+ versions

FMPA: use with Airspy and Airspy Mini


IIRC, they can all do TCP linking to DSD+.

In FMP24, the D key switches between AM and FM demodulation. Doesn't look like there is any AM demodulation in FMP or FMPA.

Thanks to cg and slicerwizard.
So, FMP24 will look for and use USB dongles by default, and FMPA will utilize Airspy devices without you having to specify between Airspy or USB dongle? That seems to be the way it works with my setup.
