Could well have been 36, it was such a long time ago and at the time I used primitive 'knob tunable' (rather than preset) TV sets with my ZX81 so I didn't necessarily know exactly which UHF channel I was tuning into.

The oscillators in those Astec modulators were free running as well, so they tended to drift slowly off frequency as the machine warmed up.

I have two ZX81s here, one is my original one and I know Dundee didn't build that because I did, although it may well be that the kit was packaged there before it was dispatched to me.

The other machine came to me in a DkTronics full sized keyboard / enclosure and the PCB may very well have been Dundee-built. In the documentary Clive Sinclair said that 'Most' of their ZX81s were being built by Dundee, but, that being the case, who was building the remainder? (The end users, perhaps?).
