Type : MP = beacon / PP = receiver   was used by paratroopers to find dropped packages and
                                                        to receive normal voice / speech information
 
Frequency band : MP = 38 - 51,95 MHz one fixed frequency in this band
                          PP = 37,050 - 51,95 MHz  tuned in this band with 50 kHz steps
 
Modulation : FM
 
Receiver sensibility : <1microV
