In summer 1998 an ambitious 2km of 3-pair plus overall screen cable was installed, following an initial mixup which had seen 2km of 3 core mains cable delivered to the station instead. | In summer 1998 an ambitious 2km of 3-pair plus overall screen cable was installed, following an initial mixup which had seen 2km of 3 core mains cable delivered to the station instead. | ||
The three pairs were assigned | |||
* Red/black: video | |||
* Green/black: left or mono audio | |||
* White/black: right audio | |||
though at the time of installation stereo audio stopped after the sound desk. | |||
Timing was opportune as this was the same summer that a private contractor was installing about the same amount of cabling for the one-per-room campus telephones for student's bedrooms. Often a route could be covered by following the private contractors while the covered walkway panels were removed, though sometimes they followed the YSTV installation too. | Timing was opportune as this was the same summer that a private contractor was installing about the same amount of cabling for the one-per-room campus telephones for student's bedrooms.

Installing the bulk of the twisted pair was only half of the challenge, in each college permission had to be sought to install television receivers | |||
* Alcuin - cables installed but receiver put on hold due to anticipated remodelling of the college nucleus | |||
* Library - receiver box installed intended for the lean-to snackbar, but no power available and no TV installed | |||
* Vanbrugh - existing TVs reused, prototype receiver and separate amplifier replaced with integrated receiver running off new cabling | |||
* Langwith - JCR TV added to the network on a spare SCART socket, and sub optimal bar monitor location offered by the bursar Kevin Nicholson | |||
* Derwent - was being remodelled the same summer, and a very favourable snack bar location was eventually given including bracket and dedicated electrical supply | |||
* Central hall - cable left unterminated in a grid as this link was on a stub | |||
* Physics concourse - intended to be wired baseband from the old [[P/X/002]] studio | |||
* Goodricke - left as wired from the studio directly, ultimately earmarked to come from LTC at a later date (incase YSTV ever moved from [[G/046]] as part of a James/Goodricke/SU centre branch | |||
* Biology concourse - due for remodelling, and since the cable passed through that area it could easily be spliced later | |||
* Wentwork - receiver installed along with internal college wiring to the lower JCR, snackbar as it was then, and by virtue of its location the porter's lodge | |||
In broad terms, although the heart had been ripped out of the Rediffusion system, at the start of Autumn 1998 the total network coverage was largely unchanged (Vanbrugh, Goodricke, Derwent, Langwith) except that now the images were in colour and on modern stereo sets. | |||
