Re: Import error using an OOT

[Johannes Demel]

Hi all,

it looks like there's a path issue.

In line 34 in "run_response.py" you do
```
parser.read('./ft8_qso.conf')
```
There's a good chance, that you did not load this file.
I assume this is:
https://docs.python.org/3/library/configparser.html#configparser.ConfigParser.read

The `./` part in you file name is relative to the folder where you run 
Python. It is not relative to the `.py` file.

Anyways, You might want to check which file gets read when etc.

Cheers
Johannes
