When is a hybrid not a hybrid?

He had spent a lot of his work time at Bell Labs. My MOS was Microwave Radio Relay in the Army and had to encompass comms techniques from landline telephone through radio at VHF to microwaves. Even more to a couple of GE technical reps who oversaw the installation of 24-voice-channel 1.8 GHz radio relay terminals in Japan '54 to '56. They had the knowledge at their mind's finger- tips and infused a number of us back then with some indelible information. :-) If you wish to see a bit more of 50-year-old military communications, download: http://sujan.hallikainen.org/Broadca...s/My3Years.pdf It's about 6 MB and takes about 20 minutes on a dial-up connection. Hal has a lot of information collected there, not all of it on broadcasting. |
