Hi Ed!

Not directly as edit of qsos does not re-fetch data from qrz/hamqth.

But because qsos are in mysql database everything (almost) is possible using mysql commands.
How ever there are not ready made instructions to do that.

What I have in mind is that in my alpha test version https://github.com/OH1KH/cqrlog/tree/loc_testing/compiled
It has state info built in to wsjtx-monitor. It fetches data from FCC and creates callsing=state list to ctyfiles folder (.config/cqrlog/ctyfiles/fcc_states.tab)

Modifying it with awk at command console could produce a set of mysql commands that would set state to every US calls in log.

.config/cqrlog/ctyfiles/fcc_states.tab includes:

call=state
AA0A=MO
AA0AA=NE
AA0AB=CO
AA0AC=MN
AA0AD=MN
AA0AE=MO
AA0AF=CO
AA0AG=SD
AA0AH=MO

etc...

Produce commands with awk at command command console:

cat ~/.config/cqrlog/ctyfiles/fcc_states.tab | awk -F"=" '{print "update cqrlog_main set state=\x22"$2"\x22 where callsign=\x22"$1"\x22"}' > /tmp/mycmds.sql

Will make file /tmp/mycmds.sql to have commands:

update cqrlog_main set state="state" where callsign="call"
update cqrlog_main set state="MO" where callsign="AA0A"
update cqrlog_main set state="NE" where callsign="AA0AA"
update cqrlog_main set state="CO" where callsign="AA0AB"
update cqrlog_main set state="MN" where callsign="AA0AC"

...etc ...
where 1st line is bogus but others work.
then just open cqrlog so that database engine will start.
Then type command:
mysql --socket=/home/saku/.config/cqrlog/database/sock cqrlog001 < /tmp/mycmds.sql

Replace "saku" with your username and "001" with your log number in use with this faulty log.

NOTE!
This is untested! But something like that could do it.
