It sucks. I just moved to the Springs. As soon as I have a transceiver, you'll have a hamgoon to chat with on the repeaters.

dv6speed posted:So what is the best procedure to go about tuning a dipole? I got all my poo poo to put up a loving huge dipole tommrow, including an SWR meter Make it a bit long and trim both ends equally. You want both ends of the dipole to be of equal length. Generally what I'll do is: 1. Get the approximate length using the generic formula and mark the far ends with a marker. I'll then add another foot or two so I can have enough to wrap around the end insulators and make my connections. 2. Strip the wire from the marked point to the ends, mark it again on the bare wire, then strip another inch or two from the marking. 3. Make a loop of the excess wire and temporarily connect the end of the wire to the mark I made. Check SWR and move your end point connections to get the best reading you can and mark it again. 4. Trim the excess end wire leaving enough to wrap around the end insulators, wrap them, and solder the wire ends in place at the correct point. Heat shrink or otherwise seal the ends and hang. As far as advice goes, just get it as high as possible and make sure you hang it in the correct position for what you want to receive. Dipoles transmit and receive broadside so you want to make sure the ends are opposite of what you want to catch, i.e.: if you want to receive transmissions from the West and East, hang your antenna with the end points heading North and South.

Catastrophe posted:So this is my first Friday living in Portland and I have some concerns. Are all the ham bands totally dead this weekend for some weird reason or is the pacific northwest just a dead zone compared to the jam-packed east coast where I used to live? I hope this move didn't kill my new hobby if there are no operators out here. I guess the only thing you can do now is EME or HF......I am sooooo tempted to get into EME

Hooray, passed my upgrade to General today. Now I just need to look at getting an HF radio. Any suggestions that would be good for a beginner?

So, my dad decided a couple years ago that he wanted a ham radio. Since I'm working on a computer engineering degree I happened to have enough background to vaguely have some idea of what I was doing. I sat down and looked at the test stuff and before too long got my Extra license. Then we purchased a Ten-Tec Omni VII and a 43' vertical. Since I don't live at home, I hooked up an old laptop so I could skype in and use the radio when I felt like it. My dad then worked on and got his Extra. Now, we've both basically given up on this radio. I feel like it's a shame since a fair amount of effort went into training, getting the stuff, running coax, etc. I think my dad doesn't quite have the time to learn how to do everything while I tend to just forget it's there. What's some cool stuff that you can do with HF? I think I've made something like a grand total of 5 contacts so far. I've played around with receiving PSK and SSTV but haven't made any contacts there. Should I have stuck with something more mobile/UHF/VHF instead? I think the significant lack of sunspots isn't helping anything. I was so interested in this for a bit after I got my license and then pretty much forgot why like basically every goon project ever.

Hey Markov Chain Chomp, saw you in the amateur astronomy thread. Is 100W enough for trying moon bounce on 15 and 6 meters? You'll probably need a high power amplifier to do it reliably, right? Most EME seems to go on UHF and microwave though. e: Here's a link suggesting that 750 W should be enough for moon bounce on 6M: http://web.jzap.com/k7rat/sixeme.html e: Heh, 100 W is maximum on 6 meters here in Norway. To run 1000 W, we'd have to use 15 meters. You lucky extras in the US can run 1500 W on 6 meters. Vir fucked around with this message at 05:52 on Jul 25, 2010 |

I need to get to work on my HF radio. I was gifted a ts-520s but it had a problem with it. I investigated and just recently discovered an open connection in the function switch. There's a wire that should be connected but one end of it is swinging free. :/ I intend on making a 40m dipole when I get that fixed so I can play on 40m at least. I guess those are usually resonant on 15m as well. I wish ssb radios for 2m/440 weren't so expensive. I've missed out on a couple recently. One was a 706 with bad HF finals but it worked fine on 2 meters and also to receive HF. $200, I emailed the guy as soon as I saw it pop up and he emailed me back 4hrs later to tell me it sold already.

dv6speed posted:So, am I to assume you are doing step 3 on the ground? Doesn't that change the SWR measurement from what it'll be in the air, or is that not big enough to make a difference? Yeah, step 3 I do on the ground. It's a lot easier than making the connections, hoisting the thing up into the air, testing, pulling it down, making minute changes, repeat. As long as you aren't spreading it out over something that will short the wire to ground and use the same coax/ladder line run you're using to connect to your shack, you should be A-OK.

I've been playing around with calculating RF exposures, in preparation for setting up a HF antenna. I think I'm doing something wrong, because my math shows that even my 5w HT is out of compliance. I'm really confused. Is this really the case?

Oh, also keep people away from it while you're tuning it up. I'm sure your power will be set low, but there's no reason to risk anyone getting RF burns.

I think you're suppose to have it 1/4 wave above ground for the best results. I don't know if that affects your swr or not though.

Anyone got a good recommendation on a good mobile unit I can throw in a truck. It would be nice for it to scan quickly, and maybe do crossband repeat. I've seen the new yaesu has a rig that can do it, and I think kenwood makes a good one, but something without the brand loyalty dip shits on eham.

Checking in to the thread, still temporarily QRT and just waiting for the wedding. After sept. 18th I have been given FULL LICENSE to put whatever wire/antennas I want up. I just gotta keep the yard pretty for the wedding weekend. Current plan is 4x35 foot pressure treated masts, one at each corner of the back yard, for a horizontal loop. I won't be able to get much more height than that, but I think that will be a pretty good shadetree setup for HF considering I only want to goof with digital pretty much. Plus I'll have three verticals - one elevated, switchable for 15/10m one elevated, switchable for 17/20m one ground mount with buried radials, switchable for 30/40m Basically I'm just going to set up each antenna with a remote powered relay at the base of each one that switches a simple coil in and out of line. They'll be tuned up to be 1/4 wave at the higher band "naturally", then I will flip the relay on and adjust the coil so they resonate at the lower band. It's not perfect, but it'll do. Keep the hobby alive for a few more months till I can get back into it, eh?

Oh boy. Looking through my stuff again, I decided to finally stop putting it off and go for my Technician license, and the local club is having examinations Sunday. Borrowed a few books from the library to help refresh my memory, and took a few sample Technician exams- passed them, luckily. (Failed the General horribly, so I'll probably leave that for another time [edit: or just take the remaining five days to study for that and neglect the Technician stuff I already know].) Luck willing I'll be able to get a 2m or 70cm handheld or something before I head out to Yellowstone on vacation (drat the lack of internet there). So, is there anything I should keep in mind with the testing that I appear to be missing horribly? E4C85D38 fucked around with this message at 23:22 on Aug 3, 2010 |

The "no nonsense" study guides are great if you are doing the "memorize the answer" method. Worked for me but I didn't learn anything. Now that I'm trying to do a bit more than jabberjaw with some of the local repeater crews, it has become obvious that I need to actually learn.

I used an iPhone app to teach me all of the answers and passed the test with 100% but then got home after that and realized I had no idea what I was doing. It took more research, reading, and listening on the air to figure things out.

I think I understand the Technician stuff fairly well, seeing I've been studying it for... a while. The General stuff, not so much, but I'll get to that when I actually start HF work. Which would probably be a while. As long as I know enough not to give me fatal electric shocks / RF burns / burn down the block I think I'll be good.

My statement was for people in general, like David Hahn, the idiot who tried to build a breeder reactor in his mom's backyard or the family of hams (Hamily?) that died when the antenna they were erecting fell on some power lines. A lot of people hear 'radio antenna' and think about the metal whips on pocket radios. I had to explain to my dad why 'just hanging an antenna in my room' was a bad idea when it came to setting up my HF rig.

I picked him up here in northeast Ohio with my really lovely ten meter rig, which consists of a Radio Shack HTX 10, a dipole strung about 15 feet up in a tree, and a motorcycle battery "Power Supply." Moved up to 28.410 and made a few contacts along the eastern seaboard. I love sporadic E season. Makes my 10 watt transceiver and less than ideal antenna system not matter so much.

I recieved word Yaesu billed my "customer's" credit card for my new VX6-R (that I'm getting in exchange for a job I did), so that means it has shipped, and I'll be getting it ANY DAY this week. I can't stand the anticipation. Also I'm taking the tests for general and extra this Saturday. I'm 100% confident I'll pass the general. The extra will be a tossup... I ran out of time and haven't even touched any of the material until today. I've been experimenting a bit with 11 meter band antennas. I've learned alot of useful stuff. I've also learned I need to get myself an MFJ-269 to do what I want to do when it comes to antennas.

Well moved to a new house, and now finally have some antennas up. Currently using inverted V dipoles for 80 and 40. And a folded dipole (that I'm still setting up) on 20. Some of my other plans are, to build a wire beam for 20 metres, and a few other bits and pieces. All good fun.
