A History of GB3NN
GB3NN was originaly built by Noel G8GTZ using ex-commercial PYE PF460 units converted to 70cms uhf
around the same time as GB3NR late 1970`s early 1980`s. It`s keeper / owner-operators at the time were i belive
Tim Thirst (G4CTT) & Gordon Higgins (G3PXK).
GB3NN (RB2) was located on a communication tower at the Bacton Gas Terminal site on the north norfolk coast and was
easily accessed with 1 watt from Fakenham by G6JVF (G0FVF) on a handheld in regular QSO`S with (now silient key) Bill G8KZP & many other Ham`s in Wells-Next-Sea. Later it was located on a water tower at kelling heath near Sheringham,here it didnt enjoy the best of use and suffered badly on its coverage due to shielding of surrounding tree`s.
On 7th march 1984 a meeting was held in the upper floor room of the Shipwright`s Arm`s public house Wells-next-sea, & a new Repeater Group was formed, "GB3 NORTH NORFOLK REPEATER GROUP" Those at the meeting were G6JVF now (G0FVF) G6YAE now (G0FVG) G3PYN peter G3HRK doug (G8KZP. sk) G4OKH G6YLR G6XWO G6VBT now(G4VDC & silient key)
At this meeting GB3NN was purchased from G4CTT for £30( Repeater) + £10 (for all the feeder cable in full) using funds raised at that meet. The RSGB was then informed of a site change & GB3NN was relocated to BUNKERS HILL EGMERE (AM05f) atop of R J SEAMAN`S grass drying factory. Keeper G8KZP.... Treasurer G4VDC (mac) Secretary G6XWO.
GB3NN 1984 ..... PYE PF460 + 2 cavity filters.. 4 STACKED J-POLES each for RX & TX located 90ft apart at 77mtr ASL & ERP 12 WATTS. On 1st jan 1986 G0FVF took over the job as Treasurer from Malcom G4VDC, the following years saw the repeater serviced in 1987 by G8GTZ

On 11-1-1991 a group meeting was called & GB3TN 24cms
