[Lowfer] 630 meter WSPR last night

[J D]

It's possible, but it also could be that QRZ and Hamcall may not have as 
prompt access to Peru's ham license database.

While a false decode will show only a four-character grid, so will some 
legitimate decodes.  WSPR only transmits four by default. Thus, WSPRnet 
will only report four unless or until one of two things happens: the 
station sends a two-part transmission that includes the six-character 
grid and the spot gets uploaded by someone, or else the operator has 
previously uploaded spots himself with his six-character grid 
"attached." The database then associates it with that call sign henceforth.

To demonstrate, I uploaded a single test spot a few minutes ago of a 
simulated 22 meter transmission. I have never transmitted WSPR 
previously whatsoever, let alone with the six characters, and 
ALL_WSPR.TXT contained only the 4-character grid. But I have reported 
reception under that call many times with the full grid, so WSPRnet reports:

2020-11-26 22:22 AE0CQ 13.555400 -10 0 EM27kc 0.005 KD4IDY EM27kd 	 5 0  2

(where "kc" denotes the field QTH where all my previous reports have 
been from, while "kd" is my town QTH for purposes of distinguishing the 
simulated receive site)
