I was having troubles with SMSspot (EA, I, HA) not posting my spots on Sotawatch. Fixing it was an easy solution so I share with you:
The problem was the username that I had chosen for Sotawatch: OE5JFE/P
The /P apparently causes an error at the SMS gateway script.
Requested Jon GM4ZFZ to change my login to OE5JFE on Sotawatch and now it is working without issues.
Hope this helps
I read online that it is a pearl script that does the SMS to Sotawatch conversion. Maybe this would be also a place to fix this once and for all.
