Hi Peter,I'm using a mains filter (similar to this: http://www.amateurfunkbasteln.de/netzfilter/index.html). The power supply is a conventional transformer (5VA, 15V) + a bridge rectifier + 100uF + 100nF + 78S12 + 100nF + 10 uF. There is no difference between that and a battery here. 73, Stefan/DK7FC Am 27.03.2012 07:25, schrieb PA1SDB, Peter: Hello Jan, Tnx for your information.I tried already several way's of powering the Mini Whip, but only a battery is clean.All others who are connected to 230 volt mains give noise or QRM. I'll continue and try to find a way out. 73's for now, Peter PA1SDB |
