[Elecraft] FSK problem with my K3

[Don Wilhelm]

Stewart,

Check the construction of your XV144 control cable at the 15 pin 
connector.  There should be no connection to pin 1.  If there is, 
correct it so the connector is wired like that shown in the XV Owner's 
manual - see Figure 7 on page 11. If you do not have the latest XV 
Owner's manual, download it.

Yes, you should be able to leave the XV144 connected, and you should be 
able to work RTTY on 2 meters.

73,
Don W3FPR
