Transceiver IdentificationWhat model ZD do I have?
The Yaesu serial number on the back of the set consists of a number, a letter and 6 numbers:
The first number is the year of production: 9=1979, 0=1980, 1=1981 a.s.o.
The letter is the production month: C=Jan D=Feb E=March and so on.
The next 2 numbers are the production run: from 01 (first series) to 24 and higher (last series)
The next 4 numbers are the serial numbers: from 0001 to 9999
Identification of the model is easy by the use of the production run:
FT-101Z/ZD MK1 early Production run: 01 – 07, all in 1979 160-10m, SSB/CW, WWV rx-only, AUX
FT-101Z/ZD MK1 Production run: 08 – 16 160-10m, SSB/CW/AM, WWV rx-only, aux Only Run 16 has the new type counter.
