0c9de251be NMT: Implement Hagelbarger Code 
This will correct burst errors of received messages. If the message
is too corrupted, it will be ignored, because some element may not
match then. The digits and line signals are checked for consistency,
since they are repeated serveral times in a message.

3788b3e8a5 TACS support (variations added to AMPS code) 
These are:

- Bandwidth only 25 KHz, so lower deviations
- Data rate only 8000 KHz
- SID is called AID (Area ID)
- MIN1 coding is different

e029a6a858 C-Netz: Generator and Arduino programmer for SIM cards 
It supports the simple memory cards only. Works only with very early
phones, like BSA51 (tested so far).

An SLE4428 card must be written. The card must not have any protected
serial number area. Also the card must read all 416 written bits via ATR,
not only the first 32 bits.

4356c93afa common: Add pre and de emphasis, if the radio does not support it 
Connect to the oscillator of the transmitter - good girl!
You need to enable pre emphasis in this case.

Connect to the discriminator of the receiver - good boy!
You need to enable de emphasis in this case.
