I am just beginning to do some serious DXing on LOWFER. I am located in the dry southwest with large ground signal losses, remote from most east and west stations, yet weak signal modes seem to be a good bet at making up for the losses and having a better shot at reception and being heard. On this past Monday I focused on acquiring SIW that does use WSPR and OPERA32. I have a copy of OPERA32 but have not been able to find WSPR15 (seems to be considered as obsolete and replaced by FST4W900). I am using FST4W900. As you can see below I did acquire a logged WSPR similar FST4W900 signal right where I expected it within hours after I started the search and I am wondering if there was enough similarity between the two signal modes to give me the logged decode. It usually is days or even weeks before I get suspected false decodes and right where I am expecting it at the time I would expect early morning signal enhancement, I could win a lottery on such a long shot!
UTC dB DT Freq Message
1530 -44 0.1 1483 ` QXY/JG5LMM 13
( ' means decoded as FST4W, a non-standard call, decoded as a 20mW power to antenna )
230213_1530 0.185 Rx FST4W -44 0.1 1483 QXY/JG5LMM 13
Local OSC set to 183.700khz Decoding set to FST4W900 mode
SIW source listed as WSPR15 similar to FST4W900 but different
decoding scheme --- is this SIW but wrong decoding ? Though I would mention this ...
