DDR Type 2 – Short-wave spy transmitter

I was expecting this to be some kind of doctored RAM, based on the name!

Fun scene in Deutschland 83 has a HVA geek trying to use a 5.25" floppy they snatched from NATO into a Robotron A 5210's 8" drives. After hacking around a bit, he managed to read the floppy and it spits out a bunch of numbers in sequence. "It is encrypted" he says as the screen shows columns of numbers scroll by.

Shortly after, this flashes on the screen briefly [/g]:

    OK
    10 CLS
    20 FOR I = 1 to 64
    30 FOR P = 1 to 6
    40 FOR Q = 1 to 5
    50 A=48+RND(1)*9
    60 A$=A$+CHR$(A)
    70 NEXT Q
    80 A$=A$+" "
    90 NEXT P
    100 PRINT " ";A$:A$=""
    110 NEXT I
    OK

I read somewhere on this excellent website before they (the DDR) had an IR line of sight Morse code transmitter in active use too, albeit slightly more recently.

Curious how they determined this was a DDR made transmitter, and not Soviet (or Czech, etc.)

I love cryptomuseum.com. It's such a gold mine.

These days an Adalm Pluto with a custom firmware would do ;) or maybe a Flipper zero.

I'm probably on a list just for visiting this website
