I don't know where JTalert gets the 6-digit

grid locators that occaisionally show in the

Decodes window, but apparently when one

rebuilds the Alert database they don't register

with the first four characters ... 

Example below ... these two stations are B4

but when I ran the rebuild alert db they did

not clear but remain as wanted grids.

  

I can confirm this defect.

The cause is the leaking of logged 6 character grids back into JTAlert for Grid alerting. This only occurs for compound callsigns where their grid cannot be included in the standard decode messages and a 6 character grid has been logged, as is the case for the two callsigns shown, 4A50CRH & ZA/IK2RLM.

This has been corrected for the next JTAlert release.
