The first shot above shows a "classic" (though very dated, even in 1967) set of equipment used for 850 CPS-shift radio teletype (RTTY). All of the point-to-point HF trunks used space diversity, a radio architecture by which two antennas fed two seperate receivers.  Looking at the second vertical equipment bay from the left, below the two speakers on top is antenna "A" R-390 receiver, identifiable by the two large black knobs and mechanical frequency readout in the center; then antenna "A" CV-89 teletype convertor (demodulator); below this, in mismatched-gray paint is antenna "B" CV-89, below which is antenna "B" R-390 receiver. Below the lower R-390 is a CM-22A signal comparator, that selected the best of the two signals processed by this equipment
 
Above we see some of the HF equipment at the Incirlik receiver site used for the USAF Incirlik Airways Station (Air-Ground comms). This is comprised of R-390s on the left, and a receiver type in the center a more modern, multi-frequency receiver the nomenclature of which I do not recall. Airways comms often used large discone antennas.
