Ian:
Zooker may be giving us the best understanding so far of what was seen at KL; I have read that the Malaysian radar system was of recent vintage and purchased from Britain. So the British system appears to be what is in place at KL.
I echo your plea for (if that) for someone to tell us what the radar 'picture' out of KL is/was. The silence from that direction hinders our understanding of early events. There are no great military secrets to be kept regarding this subject; the capabilities of garden variety search radars are no secret.
There are people such as I posting here who would like to gain a better understanding of the early portion of the flight, and the absence of detailed radar information hinders that process. There is no reason for all the principles in this matter to provide less than full disclosure IMO.
