Hi All!
We’re building an 8,970kHz VLF transmitter at SP2KDS club.
We almost have everything in place:
What we still need is a generator to feed the transmitter. Required
parameters are the following:
- 8,970kHz frequency
- regulating range +-0.05Hz
- adjusting duty cycle of 5 to 45%, at 5% for two
signals at the same time
- two signals shifted by 180 degrees
A friend of mine has promised to build it but it’s been over a year now and
nothing has happened.
Is there a software which would use a soundcard with the aforementioned
parameters?
