This is an unofficial page with the sole intention of providing users of the LD-5 and LD-11 transceivers with information that will help them to better enjoy using these two radios. - DJ0IP
The SKY-SDR, ALT-511, LD-11, and LD-5 are all related products, built in Bulgaria by the same Engineering Team.* The following information comes from that Engineering Team:

USER MANUAL for LD-11:
The original user manual that came with the LD-11 was very sparce, leaving users with a lot of unanswered questions. Operationally, the LD-11 is 99% identical to the SKY-SDR. Nick, LZ1JY has taken the SKY-SDR User Manual (which I wrote) and edited it such that it is usable with the LD-11.
For your convenience, I will present the new manual here as a download.
