May I add a somewhat late comment about this product, please?

It seems to me that there are several different requirements for a transmitter 
for 136 kHz, depending upon what any individual needs.  Being able to generate 
1 kW is not always necessary.  One thing that struck me about this unit is that 
the power level can be varied over a considerable range.  When setting up an 
antenna and its connection to the feed line, it is very useful to start with 
low power (hence low voltage) so as not to stress the various components 
unnecessarily.

One thing I like about this unit is that it can be used for ordinary hand-sent 
CW.  Presumably QRSS would not be a problem.  Also, can this rig be used for 
some of the more sophisticated modes?  I do not think I have a complete set of 
the e-mails of this thread.  Please will someone enlighten me.  Thanks.
