Content preview: Mauro, the most popular mode (most stations active) is QRSS, Opera coming second. WSPR used to be very popular on 500kHz but recently it is very quiet. If you go for best SNR it depends on the time a message takes. WSPR is fixed to 2 minutes and in my opinion is unbeaten in that timeframe. In a test I did (see http://on7yd.strobbe.eu/QRSS/) WSPR outperforms QRSS3 by about 5dB and Opera2 by about 7dB. QRSS10 and Opera8 should perform more or less equal to WSPR. If you go beyond that (QRSS30 or Opera15 or even "slower") WSPR is outperformed.

The new kid on the block is Lentus that comes with MultiPSK (http://f6cte.f= ree.fr/index_anglais.htm). I haven't tested it (yet), but is looks promisin= g. And then you have an almost forgotten mode: WOLF (http://www.scgroup.com/ha= m/wolf.html). This mode has the big advantage that it accumulates the incom= ing data. 73, Rik ON7YD - OR7T ________________________________________ Van: owner-rsgb_lf_group@blacksheep.org [owner-rsgb_lf_group@blacksheep.org= ] namens IK1WVQ Mauro [ik1wvq@stmb.it] Verzonden: donderdag 26 april 2012 12:27 Aan: rsgb_lf_group@blacksheep.org Onderwerp: LF: info about better digital mode in 2200m band Hi, what is the better digital mode for starting listening 137 KHz band as "reverse beacon" (no TX)?? ("better" =3D greater number of active stations in Europe) WSPR ?? LENTUS ?? OPERA ?? what frequency is utilized for those modes ??? thanks in advance to all .. 73 de Mauro IK1WVQ P.S.: my RX station is : PA0RDT 8 meters over the roof, RACALL 1792 .. not great station at all .. in QRSS mode the only station what I can receive is the "broadcast (HI!)" beacon of Stefan DK7FC ..
