[Waverley ARS] Update on current Bletchley Park code-breaking Challenge 1 - GERMAN AMATEUR Cracks Code

[Eddie Hanham]

Heard this morning on ABC that a German radio ham had cracked the 
first of three levels of encoding.

Cant find a web reference to confirm.

However a search using "Bletchley code amateur" should bring up 
enough references or go to the museum at:

Planned Transmission Timetable for sending code

We will be using the Amateur 20 Metre, 40 Metre and 80 Metre bands for the transmissions.

    * The 20 Metre band lies between 14.000 MHz and 14.350 MHz
    * The 40 Metre band lies between 7.000 MHz and 7.200 MHz
    * The 80 Metre band lies between 3.500 MHz and 3.800 MHz

Each of these bands is split into sections with preferred operating modes. 
It is impractical to define exactly what frequency within each band will be used 
during the Cipher Challenge - the spot frequencies in the table below have proven 
workable during early testing.
