| 17:50.31 | SunSparc | HAM question: Band sizes (eg 160 meter, 20 meter, etc), these are referring to the "physical" length of a wave (peak to peak or trough to trough) and not to any physical size or other feature of an antenna. Is that correct? |
| 17:52.25 | eightyeight | correct |
| 17:52.44 | eightyeight | although, antenna length is resonant at those lengths |
| 17:53.13 | eightyeight | but you generally won't have a 160m antenna. you will probably have a `1/2 wave' or `quarter wave' length |
| 17:53.57 | eightyeight | but at the higher frequency bands, you probably have 1:1 antennas |
| 17:55.43 | SunSparc | Yeah, I was thinking, wow, if I want to communicate on the 160m band, that antenna would be half as tall as the Eiffel Tower! |
| 17:57.30 | eightyeight | a 40m loop antenna for the 160m band isn't unreasonably long though |
| 17:58.18 | SunSparc | Yes, that would certainly be more reasonable. |
| 17:58.56 | SunSparc | I assume the smaller bands are more common for general communication. |
| 18:06.01 | SunSparc | Wow, ELF wavelength is up to 100,000 km! |
| 18:10.18 | Jayce^ | hence the size of the one that detected the gravity wave |
| 18:10.45 | SunSparc | So cool. |
| 18:19.11 | programmerq | I've mostly done 2m/70cm handhelds. |
| 18:19.21 | programmerq | I'd like to get into some of the HF bands, but the equipment isn't cheap |
| 18:25.13 | jfindlay | well, gravity waves are not electromagnetic waves :-) |
| 18:25.28 | jfindlay | also, dividing up the spectrum by wavelength is also arbitrary |
| 18:30.23 | SunSparc | It is interesting to thing that at some level everything is waves. We "see" light waves, because our eyes percieve some waves as visible, our ears do the same. (Hmm... do we smell waves?) Imagine having biological receptors for ALL waves. How innundating that would be. |
| 18:30.50 | jfindlay | for example, the main scrutiny of the CMB is mainly a study of the standing wave patterns in the universe's protoplasma before it phase changed out of plasmonic equilibrium, when the ambient thermal energy dropped the threshold of the binding energy of electromagnetically imbued particles |
| 18:31.23 | jfindlay | standing waves meaning that there were resonances on the scale of the universe itself |
| 18:31.51 | jfindlay | also, you can see those same density fluctuations in the distribution of galaxies through time |
| 18:36.46 | SunSparc | Universe size wavelength. I cannot even wrap my mind around the antenna needed to communicate on that frequency. :D |
| 19:20.16 | eightyeight | jfindlay: `gravity waves' or `gravitational waves'? :) |
| 19:35.30 | jfindlay | eightyeight: gravity waves are lamesauce and should thus ignominiously surrender the name |
| 19:36.30 | eightyeight | surfers disagree |
| 19:59.01 | SunSparc | surfing is fun |
| 20:15.55 | SunSparc | HAM question: handheld with built in scanning or separate scanner? |
| 20:18.34 | SunSparc | Maybe that is not a thing these days. I just remember about 20 years ago an uncle had a separate scanning device that he used along with his main rig. Perhaps for multi-tasking. |
| 20:19.43 | programmerq | I wouldn't buy a dedicated device for it. it is probably mostly just handy for multitasking. |
| 20:21.51 | SunSparc | Cool |
| 20:22.10 | SunSparc | Looks like there is a ##hamradio channel. |
| 20:22.24 | SunSparc | Holy 400 users! |
| 20:22.26 | SunSparc | Nice |
| 20:26.35 | programmerq | yup. I'm in there too |
| 20:32.06 | SunSparc | :) |

| 21:11.48 | jlp_znc | I know people who monitor several repeaters using a scanner (e.g. Venus KB7FXB). doesn't tie up your main rig if you want to monitor several frequencies. I generally just monitor one repeater, myself, though. |
| 21:13.13 | jlp_znc | most radios have a scanning functionality that you can configure (both of mine do, but I hardly ever use it) |
| 21:16.12 | SunSparc | Makes sense. |

| 21:44.34 | programmerq | it sure is cheap, and many of the qa/usability issues have been ironed out as they have iterated. |
| 22:14.37 | SunSparc | programmerq: I guess it depends on who you ask. Several guys over in ##hamradio give it a pretty bad report. But I guess you get what you pay for. :) |
| 22:14.50 | SunSparc | Might be just fine as a starter. |

| 23:16.36 | programmerq | SunSparc: there's a vocal minority of people that hate that radio that don't actually own it. all the folks I've talked to that own it are happy for the price. |
| 23:17.34 | SunSparc | "for the price" being the key. :) |
| 23:17.41 | SunSparc | Gotta start somewhere, right. :) |
| 23:17.51 | programmerq | well, when you're talking about a 1000% price increase for maybe a 10% "quality" increase |
| 23:18.24 | programmerq | so yes, that's the key takeaway, but not in the normal negative connotation that goes with the phrase "for the price" |
| 23:18.29 | programmerq | that's my take on it anyway. |
| 23:19.10 | SunSparc | Thanks. :) |
| 23:19.26 | programmerq | I think it's mostly people in the hobby being bitter that they spent $200, $300, $400 or more on an HT before the baofengs got cheap/popular/good |
| 23:19.31 | programmerq | and they're bitter |
| 23:19.46 | programmerq | I spent $265 on mine before the baofengs really took off |
| 23:19.58 | programmerq | my same radio has dropped by $100.00 to try to close the gap |
| 23:20.31 | programmerq | but I'm not going to get hung up on it-- there are plenty of folks in the hobby that wouldn't be if baofeng didn't flood the market with cheaper HTs |
| 23:21.02 | programmerq | that arguably increases the value I get out of the hobby |
| 23:21.36 | SunSparc | Very good point. Certainly lowers the barrier to entry. |
| 23:22.39 | SunSparc | Hard to beat the "Frequently Bought Together" package on Amazon for the radio, cable, and Nagoya antenna: http://www.amazon.com/BaoFeng-UV-5R-Dual-Radio-Black/dp/B007H4VT7A |
| 23:22.41 | programmerq | honestly, I'm tempted to get a couple of the baofengs to use as backups. |
| 23:24.45 | programmerq | I was looking into getting more accessories for my yaesu a while back. I don't remember all the pricepoints, but I wanted a speakermic, second battery pack/charging dock, and maybe an earpiece |
| 23:24.50 | SunSparc | For the price, not a bad idea. :) |
| 23:25.07 | SunSparc | Hamstudy tells me that these antennas are pretty good: https://signalstuff.com/product/super-elastic-signal-stick/ |
| 23:25.40 | programmerq | the cost for all the yaesu original parts, I could fully replace my current yaesu radio+accessories, get all those accessories, *twice* |
| 23:25.57 | SunSparc | Wow! |
| 23:27.12 | programmerq | plus, all the baofeng parts+accessories are on amazon prime. the yaesu parts not as much. |
| 23:28.12 | SunSparc | Quite the incentive. |
| 23:28.41 | SunSparc | Make it hard to not just get one. |
| 23:30.04 | programmerq | yeah |
| 23:30.10 | programmerq | I already have two HTs, and I want one. |
| 23:30.52 | SunSparc | Hobby toys needed = N+1 |
| 23:31.53 | programmerq | SunSparc: the biggest caveat is probably the fact that it is nearly (completely?) impossible to program without a radio cable. |
| 23:32.12 | programmerq | but once you get it programmed the way that makes sense for the area, you are pretty much just set. |
| 23:33.27 | SunSparc | Sounds like a fun challenge. |
| 23:33.28 | SunSparc | :) |
| 23:33.57 | SunSparc | I gotta head home. Thanks for all the good ham advice today. |
