Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Content-type: text/plain; charset=windows-1252; format=flowed MIME-Version: 1.0 Content-transfer-encoding: 8bit From: YO2IS Hello from KN05ps, am still around following the LF-net debates and learning from others experience. Just finished for the last weekend the new Loop, a 2m diam. hexagon, 10 turns in a good quality multifilar telephone cable. The loop tuned sharp on 137 KHz with abt. 400 pF, and can rotate it with a h.m. rotor used earlier with my 2 el 50Mhz Quad !. The loop is inside the roof space, conected to a KRLR style preamp. (BF 247, BC 252) and feed with 8m 75 Ohm coax to LF/80m convertor using a single uA 796 & a 4 MHz Xtal osc. Signals of the DCF 39 are at S9 plus and can hear equaly well the 135.8 signal from Greece. The most important is that got a sharp null on the local mains noise. Have heard some QRS CW on 137,.. KHz, but am not familiar to DSP, my PC (486DX50) seems to be inadeqaute...do hope my EME experience will help to copy some weak CW, hi. Have read in the hungarian ham magazine "Radiotehnika" 3/99, that HA2PP and HA3IS are interested in LF. Also HA8BE, a "top band" specialist, told me on 2m FM, that he will be soon QRV on 137 KHz. After an enthuziastic start, no more signs about LF from Slovakia (OM). 73 & DX, Szigy.
