As a tip for the U.S. technician test, you can also find a question pool somewhere online. It includes all the possible questions (around 650) so I suppose you could read over that if you want to make sure you pass the exam.
http://www.hamtestonline.com/study.jsp

It's a pay site, but they have free trial memberships that expire if you're not active for 30 days. They have all the question pools, and have practice exams that mimic the real exams in question frequency.

Interesting! I used to be a DJ at our University-run FM radio station (V89 at Florida State University) and the FCC rule for us was that we had to ID our station every 30 minutes. We had some interesting rules since we were a non-profit.

I was curious what rules that apply to FM stations also apply to HAM radio.

Rules that applied to us:

-Couldn't make calls to action: "Go on down and vote!", "Buy this product!", etc.

-Couldn't make "quality" judgements: "Product A is the best", "Product B is crap". (In the case of our news broadcasts - that applied to political candidates, views, etc.)

-No cursing until 10PM - 6AM (The FCC called this the "Safe Zone" - but we never cursed period as a station policy)

-If advertising, we could not mention prices at all

-I know our actual radio engineer had to deal with this and not us DJs, but we could not transmit more than X amount of watts of power. We weren't allowed to bleed into other stations.

Hopefully knowing these rules would mean that many fewer questions to worry about.

As an aside, I'm curious what is "amateurish" about amateur radio? What is it called amateur?

And that begs the question: What is "professional" radio? Is that FM radio run by Clear Channel or something?
Amateur radio operators cannot do business over the radio. They (we, now, since I passed the Tech exam recently) are forbidden from selling things except for on an occasional basis (like for selling ham equipment), and amateurs can't broadcast for the general public. Beyond that and some restrictions on profanity that I still don't quite understand despite studying a fair amount for the Tech exam, amateurs aren't really restricted on speech. It's highly suggested that you remain polite and follow good engineering practices, but we can discuss politics and religion and whatever. Amateurs are limited to using enough power to achieve communication, but in reality are limited to 1.5kW. We cannot intentionally interfere with other stations, etc.

Professional radio would be radio stations licensed for business use, like advertisement. Saying FM radio doesn't really cover it exactly, as that's just a modulation scheme. Transmissions in the 6m/2m/70cm bands are FM transmissions, but they're still amateur bands.

Anyway some awesome Extra will probably come along and clear things up, but that's what I've taken away from my studying for the Technician exam (which you should take, its really easy!).

With the supervision of a friend and some beer (probably too much beer...), I built this neato twinlead jpole antenna:
http://www.qsl.net/wb3gck/jpole.htm

I don't have my HT yet so i can't tx, but it seems to work decently for receiving on 2 meters. It seems to perform about as well as my magmount antenna, but I haven't done a side by side comparison.

Construction was fairly easy except for stripping both sides of the twinlead to solder the coax on. I just ended up cutting it in half and soldering it back together where i attached the coax, because stripping a wire in the middle is really hard. The joint that attached the coax shielding wasn't super great, and broke pretty quickly. I've since fixed it, and took it for a spin on my balcony. :) Oh also I put some heatshrink over the notch it has you cut out of the 1/4 wave side to make that a little less crappy.

For the amount of time, effort, and money I spent on it (maybe 1.5 hours and $free since I used leftover parts), it's pretty awesome.

I just did a quick test with that j-pole versus the magmount.

I was listening to N5MJQ and was able to catch two guys talking on the input frequency. On the magmount I can't get either of them on the input.

I also had my first QSO on that repeater using my new HT (that came in today :))

Hmm. I'd have to install it so no wire showed at all (one of the reasons the HOA got called on me was apparently due to a loose wire hanging over the edge of the roof from a previous tenant's eff'd up satellite dish installation), and I'm not sure if I can manage that, but it's a start. Thanks for the tip, I'd heard of these things but never really gone looking. :)
After reading this I decided to bone up on the FCC's take on amateur radio versus HOAs. Turns out they don't give a poo poo!

This is one more reason to never buy a house that's deed restricted if possible. This HOA business really rubs me the wrong way, as people who have no investment in your property can dictate what you can and cannot do with it. :argh:

And so, I've got one question (for now) - I suspect it would be, but would an HT be sufficient a rig for a newbie?
I've been very happy with my HT, and I'm a newbie. I just keep an antenna near my desk and an antenna on my truck for when I go mobile, and so far it has been working out well. It was especially great while camping this weekend. I love that it's portable and fits in my pocket and is battery powered.

I'll be looking at a mobile rig before terribly long, though. The HT + mag mount antenna works pretty decently, but I'd like something a little more permanent. Also the mag mount came off my truck while driving down the interstate today :wth: due to my speed (70MPH) and a very strong headwind. Luckily it fell into the bed and was undamaged.

I just got back from vacation in the Bahamas. I was disappointed that they don't reciprocate tech licenses with the US, so I was unable to operate. However, when I got there I found no activity on 2m or 70cm. Taking my HT to do some listening was a waste of pack space :(

However, everybody in the area I was in seemed to live on marine band radios. You could call *anybody* in various towns on channel 16, like grocery stores, the town clinic nurse (we had to do this at one point, as a fellow on our boat cut his toe badly hunting for some snails in some mangroves :eek: ) , restaurants, etc. That was pretty neat. Listening to it wasn't as interesting as the local greybeards on the local repeaters, but it was still pretty cool. Boat names are often absurd so its pretty great listening to Papa Nasty calling Harbor View Grocery.

Time for more mobile ham pictorals.

I was putting my bike on my truck, and wanted to take a couple pictures for separate reasons, so I figured I'd get some shots of my crappy radio setup (mounting, power) out of the way.



I got my tags in last week!
I want to get a better antenna, maybe 1/4 wave on 2m, and mounting it with something like this mount in the rear passenger-side stakehole on the side of the bed. I'd have done it already, but I've got some other things I'm saving my hobby funds for right now. The mag-mount is really annoying, because even the small one I have can't make it under my garage door. I always have to remember to pull it off before I park my truck at home.


Here's where I stuck that Icom IC-208H. I had less room under there than I thought I would have, and the dash presented some difficulties. There's a lip on the back edge of it pointing downward, which I had to file down to be able to mount the radio. Also this is kind of janky because it's held up there with one screw right now. It hasn't fallen down in the couple of months since I mounted it, though.


This shows the relative position compared to the wheel. Getting the mic is a bit of a stretch, as is hitting the power button. Aside from that, its pretty nice. I also wanted to showcase my rockin 1990 Ford Ranger dash and gear cluster.


This shows how I connected it to the battery. I just jammed the ends of the power cable into ring connectors, and got some vicegrips to mash them on with. Seems to work, though it trashed the plastic bit as you can see. My biggest concern with this was getting whine off the alternator, but the little I do get isn't terribly loud, and I'm not convinced that its audible when I tx. The last concern here is that I have to remember to power off the radio when I kill the truck, or it will drain my battery. So far I've left it on once, and only for an hour.


Here's how I routed the wire to a nice premade hole in the firewall. I just used the existing areas wires were running through after I put some of that wire shielding stuff on. I love my truck because there's a ton of room to do stuff like this.


I was so happy when I saw that grommet in the firewall and was able to easily remove it. I cut an X in it with a razor blade (just the blade, because I couldn't find a proper box cutter. I'm safe), ran the wire through it, and jammed it back in. I haven't noticed any leakage since, but I haven't exactly driven a whole lot in the rain since then. I'm considering sealing it up with some silicone.


And finally, here you can see power going behind the pedals and over the steering column to my radio. Note also the lip I had to file down to mount that guy. That was a couple hours worth of uncomfortable filing. One last interesting thing is how much spoogy crap is on the underside of the dash there. This truck was detailed not two months ago, so I think the guys that did it missed the underside by a fair margin.
