It runs with all the popular browsers. Online as well as offline when downloading the Java-File to your PC.The URL is: http://home.t-online.de/home/Bernd.Grupe/homepage.htm My qth-locator is JN49JV and its 40 km down of Frankfurt/Main.Due to the near big radio stations - DLF 153kHz, DCF 77 and intermodulation by 129 kHz(GPS) etc. - you can believe me, that it's hard to get an audible signal in NCW. Since April i tried to connect dk8kw(Geri) on lf. But it was just the one-turn loop-ant. which i have built at least, to get Geri at friday last weekend with quite a high O quality in scw-mode. This good performance of loop-ant. brought me to write this mail to all of You, who suffered from similar bad conditions. Try a loop and look for gd dx. 73 bernd, DF8ZR TX-ant.: marconi 10 m high; coil 2.3 mH RX-ant.: selective loop, 2 m diam pw: 20 watts homemade rx: PCR1000 ICOM with selective preamps
