[Elecraft] K2: Filter and BFO Settings for RTTY

[Jon Perelstein]

Don,

Thanks for the response and info.  

The wording in the Operating Manual made me think that the same values are used 
for RTTY as for SSB, my mistake.  I used Spectogram (surprisingly easy) and have 
everything working nicely now.

On the digital transmission heat issue.  The rig is ok on 1-2 minute digital 
transmissions (e.g., 1-2 minutes of PSK at 30 watts).  It'll warm up a bit, 
although nothing uncomfortable, and the internal fan can handle it.  The problem 
is longer transmissions.  For example, I do a lot of file sending for EmComm 
simulations and those transmissions can run 5-10 minutes at a time.  The area 
above the power transistors gets very uncomfortable on a long transmission like 
that and people notice drift in my transmissions.

For now I've got a desk fan pointed at the rig when doing longer transmissions 
and that's keeping the rig cool and stable.   I'll find myself a muffin fan or 
smaller desk fan at the next hamfest.
