IntroductionOverviewThe PK-96 is a 1200/9600 baud, packet-only controller that sets a new standard in the amateur radioworld. As a new owner, however,

When you change channels, the channel you changed to will have the packet header information of the sta-tion that just connected to you. Remember that

6. MailDrop OperationOverviewThe PK-96's MailDrop acts like a small post oflice-it uses a subser of rhe well-known W0RLI/WATMBLpacket BBS command

By the way, you have full control of your PK-96 while your MailDrop is on. You can connect to, and chatwith, other stations while someone is using you
