Hi LF
I have exchanged a couple of email with Jason (J1BPL keeper). For the reports
he provide in HF it is clear he is mixing
few SDRs around the world. He reports to keep own SDRs in Ontario and Domenican
Republic. But the reports from EU
stations may be from Twente or any other. He explains the reson of using that
callsign
Anyway, not fair game and confusing the whole system as propagation monitor tool
After all WSPR have also its ghost .... not only Opera !! ;-)

Message from Jason follows :
J1LPB was used because the it conforms to the WSPR protocol.
1) One or two characters consisting of A-Z or 0-9
2) One character which must be a number, 0-9
3) Two or three characters which must be A-Z These restrictions are placed on
the callsign in order to satisfy the requirements of the WSPR and Opera
encoding algorithms.
J1LPB is used at my primary QTH, J2 and J3LPB are in separate locations, one in
the Dominican Republic (J2) and one in Parry Sound, Ontario. Each station is TX
capable but right now RX only and remotely controlled by me from my home until
I get to each location. At that point I can start running TX on the ISM bands
"flea power" using WSPR.
J for Jason, number for station, LPB for Low power beacon
I agree SWL would suffice for simple reporting but it keeps things simpler for
me to know which station and the fact that it is unique, that J1 is not defined
as a prefix in the world that I know of (Japan, you might think but I have
never see a J1 call from there, nor J2 or J3)
