[Elecraft] RTTY Problem

[Jim Rhodes]

Don, remember that the RTTY generated from the terminal window does not use
the FSK interface. I was reminded of this last week when trying to diagnose
a similar problem. (Which I have yet to solve, but will now have to wait
till I get home again) I was thinking that the problem was with my HB
interface, but I didn't have time to swap out the opto in the box for a new
one. Maybe I have the same problem. Won't be back till next Friday so that
will have to wait till I have some time off. I would just get a steady tone
using MMTTY/Writelog, but got transmitted & decoded RTTY using the terminal
mode. First thing I will do is put the scope to the FSK port to see if the
signal is getting that far. If so the problem is internal, if not then
probably the 2N35 is gone in the interface. Will post here once I find out
anything.
