I have a fox for the 80m band, and I’m wondering who has gear to receive the signal.
It is a real CW signal on the color burst frequency, roughly 3.579 MHz.
One possible receiver is shown here: http://crkits.com/r3500d.jpg
The fox has not been deployed. I’m just assessing the interest level of such a fox hunt.
