Hi Stefan,

JA7NI is using 2FSK instead of 4FSK WSPR.  JH1GVY has devised a method that can utilize a DFCW tx to transmit quasi WSPR2.  The 2FSK WSPR seems to be 3-5dB weaker, especially when there is QRN/QRM.  Even so, KL7L and UA0SNV/UA0AET might have a chance of receiving, but I don't think he is receiving WSPR for the time being.

LF,

This morning i saw JA7NI on the WSPR database/map. As far as i know he was only QRV in QRSS/DFCW/CW during all the years. Maybe the very high number of active WSPR stns in JA convinced him to try this mode.
So far there were just "local" decodes, not sure if it was a QRP test. But it could be interesting for UA0SNV, KL7L and DU1GM? Maybe even interesting for me, if he is receiving :-)
