Does anyone know much about the changes at Truskmore in the late seventies ?
I was young at the time but I remember (barely) we used to get RTE on 405 and 625 we were using an ancient TV with indoor aerial. My Dad maintained the picture was better on 405 (maybe it was on the dodgy setup we were using) although there was the odd day when reception seemed to be better on 625 (Channel I although it also came in on Channel H which I think might have been the Croaghmoyle relay back then)
Then 405 disappeared but then there was something (this is the bit Im most curious about the hows and whys of) aerials were changed from vertical polarisation to horizontal.
Later (weeks/months/a year Im a bit fuzzy on dates) I remember looking for the newly opened RTE2 on a (rather big) tuning knob on our TV. I found it on Channel 10 (Yes It was 625 but our channel selector only had I H F D and B lettered positions -odd the things that sticks in ones mind)
We also had some friends (who had an outside aerial and lived higher up) who used to watch something called UTV (presumably on 405 from Strabane as they didnt have any BBC stuff) but it disappeared around 1981. (This could have been a fault with their set or aerial as 405 from the UK remained on until 1985 unless there was a power reduction ??) at the time they blamed it on a local pirate radio station which had just opened although their UTV never came back after the pirate closed !
Later (c 1983) BBC1 appeared very weak (and only B&W) somewhere on the VHF band (by this stage we had progressed to a 625 only colour set with preset tuning but no way of identifying what channel/frequency one was tuned to) this lasted for a few months (reception varied from totally unintelligible to watchable-if-there-was-nothing-on-RTE) until one day it disappeared suddenly mid-programme and never returned Ive never been to determine the origins of this VHF signal (possibly a spurious signal from a deflector or someones masthead amp gone haywire) There was a UHF deflector in our aera although through some freak of local topography we never could get a satisfactory signal from it (even with a proper UHF aerial/amp) although neighbours four houses up the street could (sort of)
Later I came across a World Radio TV handbook (1986) which listed Truskmore as using Channels J (RTE1) and G (RTE2) Dont remember RTE1 being on anything other than I from Truskmore So Im assuming it was a misprint although I had a portable set ("Renyolds") for a long time which had all the channel positions except I but which got RTE1 on J (Croaghmoyle at this stage was on D for RTE1 and F for RTE2) later when I was living in Dublin (and had access to cable) I was able to confirm this thing didnt actually get Channel J but its Channel I position was mislabeled as J
So to clear up some unanswered childhood questions does anyone know:
1) The reasons for the polarisation change (if it ever happened) at Truskmore and how it was implemented
2) Any better reasons for the premature disappearance of our friends UTV signal
3) Did Truskmore ever use Channel J and is so why
4) Why some old TV sets had incorrectly/misleadingly labelled channel selectors.
As a kid I was fascinated by the nuts and bolts of television although for the large part I didnt have the same interest in (most of) the actual programmes as my peers. (Come to think of it..........)
