The system might have been Pacnet? This was on around 164 if I remember correctly and just permanently transmitted (packet?) data which did sound like a big diesel running around 1000 RPM. I haven't checked to see if it's still active recently but it was prolific in the nineties. It only occasionally broke through to our receivers probably when there was a bit of rectification in the metal joints on the masts more than anything else. I suppose GPRS and the likes have taken over nowadays. The other paging system was ERMES if I remember correctly, but these didn't seem to cause trouble. I think it was the sheer Tx power that made breakthrough more likely with POCSAG.
