I haven't really monitored traffic other than that in the last few
years. Someone was talking about tracking a drone aircraft with a
search light via APRS one year. Mostly I try to take a break from
work when I'm out there.<br clear="none">
<br clear="none">
There's a fair amount of radio infrastructure out there year-round,
up on a mountain and in the town of Gerlach. I've thought about
building some deployable weather stations with nephelometers to
measure dust levels in real time. It'd be interesting to put them
at several locations around the site and generate an animation after
the fact showing the dust storms blowing through. They'd need to be
rather high-range sensors, since the dust can get so bad you can't
see three feet. Building a nephelometer doesn't seem difficult but
I don't know if I could keep the sensors clean enough to stay
accurate.<br clear="none">

yeah, that project was fun. Humbolt General
Hospital lost the EMS contract right after that so
I'm not sure where the trackers ended up. They were
running half a watt on 70 cm at 9600 baud, four time
slots per second, two packets per time slot, with a
cycle time of 6 seconds. The trackers were all
motion-activated with the goal of lasting ~10 days
without recharging. They were magnetically mounted
gadgets about the size of a paperback book. A few
had their batteries die early because the sensors
were too sensitive and were triggered by the wind
against the vehicles.<br clear="none">

From a single receive site we had no trouble
covering the whole event and got solid tracks on
ambulances headed back down NV 447 out to about 15
miles where they started to get into the hills.<br clear="none">

There's also been some APRS activity among
