Which 'scope is this - the PM3305?
The earlier ones in this range used a different sort - cylindrical - which seems to be fairly reliable. IIRC, that's the type in your PM3215. But they mostly use the dreaded RIFA types, hidden under the sheet of FR4 material on the rear panel. There is a rectangular cut-out in that panel which always confused me - until I saw one of the earlier cylindrical types, which fits into the cut-out.
