This module is missing a README that explains what it does.

-** gr-error-correcting-codes
- This module intends to provide generic error-correcting code
- support, rather than implementing coding for a particular standard.
- Currently it has support for convolutional, viterbi, and turbo
- codes.
-
** gr-gsm-fr-vocoder
GSM 06.10 full rate vocoder, and gsm library
(Note that the presence of this argues for moving the G.711 code discussed above.)
POCSAG and FLEX
(gdt suspects there are blocks in here that could be generalized.)
-** gr-radar
- ?radar (not clear)
-
** gr-radio-astronomy
seems to use only standard blocks from python
