Спасибо, друзья, за добрые слова!
Это 100% DK7FC, но что конкретно он передавал...
Вот что он мне ответил:
------------------------------
Oh, ehm, very embarrassing, it is my signal. ;-)
I intended to transmit DFCW-60 but obviously the PC and/or VFO as
disturbed and so it does a frequency shift sometimes. It has to do with
(sub-)optimal antenna matching, as it seems.
In a few weeks i will replace the DDS VFO by a TX converter that mixes
125 kHz+X (X=11,7...12,8 kHz, generated by SpecLab) to generate the TX
frequency. Then, i can make QSY remote controlled.
Thank you for the screenshot. I am happy to be visible so well in
Moscow!! Good RX antenna!
Best 73, Stefan/DK7FC
