the complete designation of RA 1771 and 1772 receivers alows to identify the mounted optional components:
format as follows:
1st suffix / 2nd suffix / 0 / fourth suffix / fifth suffix / sixth suffix

1st suffix: filters fitted (6 available slots)
A: symmetrical 0,3 / 3 / 8 kHz, sideband filters USB 3 / LSB 3 kHz
B: symmetrical 0,3 / 1 / 8 kHz, sideband filters USB 3 / LSB 3 kHz
C: symmetrical 0,3 / 1 / 3 / 8 kHz, sideband filters USB 3 kHz
D: symmetrical 0,3 / 1 / 3 / 8 kHz, sideband filters USB 2,7 kHz
E: symmetrical 0,3 / 3 / 8 kHz, sideband filters USB 6 / LSB 6 kHz
F: symmetrical 0,3 / 1 / 8 kHz, sideband filters USB 6 / LSB 6 kHz
G: symmetrical 1 / 3 / 13 kHz, sideband filters USB 6 / LSB 6 kHz
H: symmetrical 1 / 3 / 8 kHz, sideband filters USB 3 / LSB 3 kHz

2nd suffix: frequency standard fitted
0: no internal frequency standard, external frequency standard required
S2: type 9400 frequency standard
S3: type 9420 high stability frequency standard

3rd suffix: always 0

4th suffix: ISB filter identification
