Thanks to excellent work by Derek G3GRO the GB3LF repeater is now on the air from Crawley on 144.9875 MHz. It's relaying the entire 136 kHz band as an upper-sideband signal. The 136 antenna is Derek's Loran-cancelling loop and active vertical combo. I put my Marconi TF2008 sig. gen onto 137.5 kHz and fed a measured 100 milliwatts RF into my inverted-L antenna. GB3LF "heard" it and relayed it back to me; clearly visible on Spectran but only just audible. Estimated antenna eff. is .03% so erp was about 300 MICROwatts. Distance is about 11 miles/17.6 kms. Derek will be describing his repeater on Saturday at the LF, sorry, HF, convention.
Walter G3JKV.
