If you have problems installing or using Mortty, look for answers on the Mortty groups.io reflector. You do not need to register, or login, or even have an account to search for a solution to your problem. (Although you will need to register if you want to post a new question.)
Mortty@groups.io can be found HERE.
You can also send questions to the Mortty developers: Hardware – N8AR Steve (<hiscallsign>@arrl.net); or Software – K8UT Larry (<hiscallsign>@arrl.net). However, if your issue relates to using a Mortty Keyer on a specific transceiver or with a specific logging prorgam, you are more likely to get a qualified response from a kindred colleague on the mortty.groups.io reflector (on which Steve and Larry also participate).
if you have problems with the mortty.net website, notify its webmaster – Larry K8UT
