MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: On this side of the Atlantic, US Lowfers are experimenting with a new weak signal mode called "WOLF" developed by Stewart Nelson, KK7KA. It has proven to be far superior to QRSS(S) mode in both off air and on-air tests to date. Lyle Koehler, K0LR conducted off air tests where he mixed a random sample of LF noise with the desired signals from a variety of modes. The results were: CW (by ear) -18db below the noise QRSS (3 sec dots) -27db below the noise QRSS(S) (60 sec dots) -31db below the noise WOLF -40db below the noise These tests have been further confirmed by on-air tests as well. Despite the Springtime QRN, record breaking receptions in WOLF mode have been made in the past few days including Stewart's reception of the XM(GR) beacon at a distance of 1,874 miles with a 1 watt input (2 milliwatt ERP) beacon. I urge LF'ers on both sides of the pond to investigate this exciting new mode. It offers the promise of Trans-Atlantic QSO's even with current US power limits...and certainly with the type of ERP common in Europe and Canada. Please note that not only is the weak signal performance of this mode superior to QRSS but also that more information can be passed in a given time frame. Currently, WOLF uses a 15 byte message format that can be totally unknown to the receiving station (AS WAS THE CASE IN ALL TEST TRANSMISSIONS SO FAR) resulting in little doubt that an actual reception or QSO has occurred.
