Hi Adrian,
I presume you're referring to ther <.....> JO33QB ?? That will be a station that has checked "Force 6-digit grid square.

Re: WSPR no callsign decoded

When you tick the box to force send 6 digit grid, the program then no longer has sufficient space in a single transmission to send all the information requested of it, so it must break the information up.
So one transmission it will send the call, 4 dig grid and power level.
The next it will send the call as a 15 bit hash code, 6 dig grid and power level.
If the 15 bit hash code is received before the full callsign has been received then the <...> is displayed.
Once the full callsign is decoded the program recognises the hash code and fills in the blanks.
An explanation of this is given the the WSPR 2.0 user guide under the heading Special Message Formats.
