M39 was run by the Czech military intelligence. It used the same frequencies as M10. However, it didn't transmit conventional 5-figure group messages.
The transmission format is given below. Standard five dashes were used for zero.
| 458 | 458 | 458 | 76621 | 76621 | Rapid dashes |
| 3-figure ID | 5-figure group | ||||
| Repeated for 2 minutes | Repeated for 15 seconds | ||||
| Repeated with different 5-figure group | |||||
M39 had no specific outro, it simply ended following the last series of dashes.
