I run a AIS receiver here and have recently received stations up to
447 KM from my location on the Ma. coast. The AIS receiver is set
for around 162MHz. Tropo ducting is common around this area this
time of year. Steve KB1CHU<br>

<div>I hope they turn it back on soon -- I'm well away from my

<div>I'm a bit baffled -- did I actually work VE1VZ directly?
According to aprs.fi, that's 147.9 miles. But when I look at
line-of-sight formulas based around height and earth's
curvature (<a moz-do-not-send="true"
href="https://en.wikipedia.org/wiki/Line-of-sight_propagation">https://en.wikipedia.org/wiki/Line-of-sight_propagation</a>),
I work out something like distance in miles = 1.41 x square
root (of 1500 feet), or around 54 miles. How'd I work a
station 147 miles away across the Bay of Fundy on 2m?<br>
