[Lowfer] Puzzled about the LF database entries...

[Garry Hess]

Neil, such bogus WSPR reports happen because the listener doesn't 
properly program the dial frequency (which is to be in MHz). WSPR 2.0 
has no BAND choice for frequencies below 600 m but WSPR-X includes the 
2200 m band. In either case though the dial frequency can be manually 
programmed. If the user is actually listening on 20 meters (14 MHz) like 
K0ZDK was, but programs in a dial frequency of 0.014... instead of 
14.000, the result is like you observed. If you examine the WSPR 
database for K0ZDK 
(http://www.wsprnet.org/olddb?mode=html&band=all&limit=200&findcall=&findreporter=K0ZDK&sort=date) 
around 0700Z you'll see the reports switched back to the correct 20 
meter frequencies. You can also confirm that reported decodes on 
0.014..., for example of WA3DNM, were of stations always on 20 meters.

I've been using WSPR-X and last night got a couple of bogus decodes on 
600 m. Other software versions false too on occasion, especially when 
big signals and their IM products are simultaneously in the passband. 
Can't do anything about that, but we can all try to make sure we use the 
right dial frequency.
