Meanwhile this frequency range is free as the Bundes= netzagentur has confirmed last year. Transmitter is an Pr=C3=A4citronic GF62 Level Generator actually at 8,79= kHz. PA is an old homebrew NF-Amplifier with 2x 2N3055 and about 40 Watt= at 4 Ohm into a 100V ELA transformer. Antenna is a T-Antenne of 10m with= 20m top capacity and poor ground. Receiver is a portable sferics RX that I built some years before (AATIS).= Unfortunately its whip antenne is highly influenced by trees and houses. The fact that I can hear (!) my beacon in normal CW up to 100m in an city= environment with a highly unmatched antenna makes me believe, that in a= better environment and with a matched antenne and with help of ARGO one= can make tests over longer distances. But even from my QTH in the city th= e ODX ;-)) surely can be improved. The mean problem now ist how to match the antenna . . . - or using ground= antennas vor TX, RX or both. vy73 Horst ___________________________________________________________ NEU: Mit WEB.DE DSL =C3=BCber 1000,- =C2=BF sparen! http://produkte.web.de/go/02/
