Hi, I have an older KAM all mode TNC that I am trying to set up for RTTY
using AFSK. I have it wired for the Packet Jack on the radio and the HF port
on the TNC. I am using the Yaesu MarkV. I am able to decode RTTY when I am
in RTTY mode, but cannot transmit unless the radio is in Packet mode. I
John,
You are not doing anything wrong. The Yaesu transceivers operate
AFSK/PSK in PKT mode and FSK in RTTY.
If you want to use the RTTY mode setting on the Mark-V you need
to connect the FSK signal (Pin 5 of the 8 Pin DIN) and Ground
(Pin 2 of the 8 Pin DIN) to pins 1 and 4 respectively
