A Solar Flux Index of 92 also helped. <\/span> My shark also made it across the Atlantic (and half the Med!) Mauro IK1WVQ’s grabber made this nice capture (looks like this was around dawn at his location):<\/span><\/span><\/p>\n

\"\"<\/a>I measured the voltage at the antenna terminal this morning. Less than 2 volts peak. Assuming a 50 ohm load, that’s about 80 milliwatts. This is all especially gratifying because yesterday I was out in the backyard with a slingshot and a fishing reel, putting a bit more wire into the trees. It worked! <\/span><\/span><\/p>\n

Here’s the transmitter and the schematic. FSK is from a simple two transistor multi-vibrator (G0UPL’s circuit — you can see it in the lower left):<\/span><\/span><\/p>\n
