Ham Radio Questions

Got my general years ago but never ended up getting a proper setup. HamTestOnline is great; worst case just do enough practice questions an you pretty much memorize the answers.
That's what I used. 27h of study total for both Tech and General. Nice site. Although I did get some questions that were close, but not the same as what they had on HTO.
That's good stuff, we should all totally be putting our callsigns in our sig lines now...
(KK4DPX).
I'm actually playing with a simplex repeater right now based off a baofeng that is inside an ammo can to get past electronic line of sight limitations up in WV.
I was playing with the APRS and the GPS logger on the HT. When I imported the GPS data into Google Earth it showed me parking my truck, getting out, getting stuff out of the back and walking into my house.
Some spooky shit.

You need to get on apsr.fi so we can track your movements

I was. Then I turned that shit off (at least when I''m not in the woods).

You could have had a decade-old Garmin GPS III+ and have the same track.
I just added a field to our user profiles for your ham radio callsign. If you populate it, it will show up beneath your username on your posts, just like the old EE BBS. Try it out!
Talk about GPS. Havent had to use one in years; last one I had was a Rhino 650 IIRC. Remember when I had a full Pelican case of different cables, so I could upload maps to various GPS units our guys had overseas. Quite before the storage card units came out.
LOL, you don't need to have a GPS receiver "oriented" in any way. Even the antenna doesn't need to face the sky, however it is better to have it this way.
GPS has always been damn accurate. It was accurate enough for airborne imaging before the selective availability was turned off (in 2000). Now you can almost count on a decent receiver to be within 1-2 m circular error (and maybe 3-5m vertical error) if most of the sky is visible.
Maybe oriented was a bad word...maybe calibrated? Acquire multiple satellites to get a better location?
I was never in my backyard - my truck is always parked on the street. So the initial readings were off by a good 10-20 meters. When I first turned it on and set it up I was inside. After being outside for an hour or two, the accuracy looks to be +/- 1m.
That's what I meant by oriented.
?
GPS receiver does not transmit your location anywhere (unless you _are_ using APRS). All it does it tells you where you are.
Here you go, you found a way to divert the Big Brother's eye
Seriously speaking, it is a good practical test.
Now you know what your receiver's TTFF is (it is probably less than a minute, but they can take their time peeling apart all these L1 frequency messages - when you move the receiver as much as 10 miles since the last power-up), what accuracy you get, and that you need to be reasonable when you set up your APRS messaging frequency.
