@K9CWM You already have nodes on your account so you wouldn’t want to change your call to your SK friend unless you want his callsign. I assume you just want his nodes under your K9CMW callsign, correct?
If so please PM (click my picture) me with the callsign of the SK and include the 10 digit secure PIN so I know that you have access to the account. Then I will move his nodes to your account.
