[Elecraft] [K2] No RTTY Output

[Ken Alexander]

Hi Folks,

I reported this problem back in the spring but didn't
have time to act on it.  Forgive me as I re-state the
problem I'm having.

I have a K2 equipped with Don Wilhelm's constant audio
volume mod for digital operation (hope I described it
correctly, Don).  I also use a Tigertronics SL-1+
interface between my K2 and my notebook.

In LSB mode I'm able to transmit RTTY and PSK-31
without any problems.  When I change the K2 to RTTY
mode I get no transmitter output (receive works fine).
 The PTT indicator on the SL-1+ lights and the K2
receiver mutes, but there's no RF output indicated on
the K2's meter or an external power meter.

Cables and connections are fine, and as I mentioned,
simply switching to LSB gets me back on the air.

I don't get on the air as frequently as I'd like, and
at times sitting down with the K2 and using it is like
starting over from scratch.  So, there's a good
possibility that something's not set correctly. 
However, so far I haven't found a setting that would
disable RTTY output like that.

Can anyone help?

Thanks and 73,

Ken Alexander
