GB3LF

GB3LF is located 1 mile east of Kendal at 660ft ASL, map reference SD543920 and QRA IO84PH.

The antenna is located on the SW section of the mast at 35ft AGL to give optimum coverage towards the Furness peninsular and the Lancaster/ Morecambe area.

Coverage is much as the map on the ETCC website which is: South to the North Fylde area. East to Sedbergh on the A683/A684 and the North Yorkshire county boundary on the A65. North to Shap Fell, Kirkstone Pass, Grasmere and Dunmail Raise. West to Coniston and along the A5087 from Conishead Priory at Ulverston to Roose on the edge of Barrow. Coverage along the A590 to Barrow becomes sparse after Low Newton at the top of Lindale Hill.

The repeater is based on Tait PMR¬ modules for 12.5kHz channel spacing with +/-2.5kHz deviation for

TX and RX. The repeater uses a duplexer built using surplus cavities retuned to 70cm by Jan Makkinje, M1DBL. This feeds a J Beam 7047 4 stack colinear via W103 and LDF5-50 Heliax. The antenna is configured for directional operation with a south west pattern to put the main lobe down the Furness Peninsular with the half power points at Kirkby Lonsdale to the south east and Ambleside to the north west. The repeater antenna has a directional ERP of +11.8dBW/15W

Repeater control is via a Hozlogic control system identical to GB3LD with a custom programmed PIC. This provides repeater TX CTCSS timing sequence to control a remote Internet gateway provided by Dave, G6CRV at Heysham which allows IRLP and Echolink to be used via the repeater.
