Content preview: Hi Mauro, At the present, I think Opera is the most widely used. WSPR reaches -27db, not enough for covering long distances on LF. So, it's rarely used. Opera and lentus perform better: Lentus reaches -34db for 5 minutes trasmission, Opera8 and Opera32 (8/32 minutes trasmission) reach -32db and -38db respectively. In my opinion, technically speaking, Lentus is the best (it is also very good for making QSO). Lentus requires a very good syncronization among station. In addition, if you use a SDR, you may have some problems due to the latency of the SDR. Instead, Opera is very simple and very close to the "regular" QRSS.

So, my conclusions are: For medium distance beacons : Opera8 or Lentus Foe long distance beacons : Opera32 For QSO : Lentus best 73's' I5ZPO Gino (operated by IW5BHY Andrea) >----- Original Message ----- >From: ik1wvq@stmb.it >To: rsgb_lf_group@blacksheep.org >Data: Thu, 26 Apr 2012 12:27:27 +0200 >Subject: 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" = greater number of active stations in Europe) > >WSPR ??
