Border Radar and Pennine Radar
IIRC, Border was provided from RAF Boulmer on 132.9 and 134.85 mhz. This was a decade or three ago so I may not be right. I guess the service was manned by RAF ATC personnel. Then, some time over thirty years ago, the service was renamed Pennine Radar and was provided from the Manchester ATCC, now with civilian controllers at the helm. The frequency also changed to 128.675 around this time. I forget when the service was finally canned altogether, although likely succeeded in some capacity by the Scottish or Manchester centres. I remember the Air UK and then Gill Air sheds flying from LBA to EDI would route, certainly initially, outside controlled airspace, first covered by Leeds Radar then Border/Pennine and then likely Scottish. It seemed the pressurised aircraft like the F27, ATP et al preferred to go along B4 from LBA to Scotland.
