[Therion] Convert .th to .svx?

I would like to convert the attached th survey into a survex txt file. I manually set the standard deviation for distance and compass in the th and I want to see if it is translated correctly into an svx file. In the thcfg file I tried an export command to svx but it didn't give a readable output. Would anyone know how to convert the th into svx please? Thank you Francesco
