Hi Horst
This is a hardware including a microprocessor(PIC 16F877A), DDS,
devider and a small power amplifier(2W). This equipment is positioned as
just an enhancement of QRSS beacon keyer which is introduced at
http://www1.u-netsurf.ne.jp/~7l1rll/radio.html .
I am not sure on the similarity to slow hell at the moment.
All informations for making the unit will be followed at my WEB site
in August this year.
Attachment is a front view of the prototype unit for helping your
understanding.
We will demonstrate this unit at JARL Ham Fair in the end of August.
