NRAO Electronics, October 1981

RFI monitoring truck in Green Bank, 1981. This was the same truck as in the 1979 photo, but configured differently. The antenna is not mounted on the back but is a telescoping mast mounted inside the truck ; there is an opening for cables going to the mast to the left of the truck door. The equipment installed was a spectrum analyzer, NRAO radio and a CB radio. The CB was used to detect power line noise. One could not see the spectrum analyzer from the driver's seat, so the driver had to stop, go to the back of the truck, raise the mast and swung it around manually to look for RFI on the spectrum analyzer.
