You don't even need to be particularly handy to patch a 1/2" hole through drywall or a wood door frame.

SoundMonkey posted:The answer may be obvious, but this has sorta been picking at me for a while and I gotta ask. The problem with that is......drivers. Now you need to support drivers. Everyone know what serial and line level audio is. Serial is not gonna change. It's simple. And when your USB to serial adapter doesn't survive an OS upgrade because there are no updated drivers for it you simply buy a new one, rather than have a radio/scanner that you can't control without keeping an old laptop around.

wolrah posted:but for PC interface purposes the reasons you give against USB just don't make sense. While the methods you describe may be possible or even plausible, it's not what I'm seeing in the industry. Common rigs I've seen with USB ports on them have drivers. Drivers that are not included in Windows XP, Vista, 7 or 8 (which is likely to comprise the bulk of the usage) or even available from the manufacturer for anything else.. I'm talking about things like the Icom 9100 which is some composite device, or the Kenwood TS-990s which uses a CP-210x. If we agree that good radios should be outlasting computers and operating system by a very long margin (I'm still running a 70s hybrid rig on occasion) this type of thing would seem to be problematic to me.

It's like someone saying USB gamepads are worse compared to gameport because they're looking at an Xbox 360 pad that for whatever reason doesn't use the standard HID class. Ahhh, I see. You are talking about theory while I'm talking about the realities of the market as it is right now. And while I agree to some extent (there still really isn't a "universal" USB to serial driver, but C Media audio and HID certainly are), I'm not sold on the idea.

wolrah posted:The audio bit I just like and see as a feature because it would eliminate ground loops and allow a cheaper old laptop to be used while benefiting from a high-res ADC/DAC in the radio itself. To me this would be the best part. Imagine a scanner/radio with a stereo 192kHz C-Media compatible sound output set to I/Q: Instant wide band SDR output in a well understood format. Add additional channels for the specific setting of each VFO. It would kick rear end. What I'm not clear on/why I'm not sold is how do you control the radio (a-la-CAT-control)? Serial is super well understood. HID is also well understood, but how do you use that in a generic enough way for sending what amounts to AT commands. I've never done any HID device programming, so maybe there is something obvious I'm missing. But I sure as poo poo know I can do something as simple as cu things back and forth to a serial device on the CLI if I need/want to.

SoundMonkey posted:Just using this as an example, since it's gigantic overkill for this application, but an Arduino Leonardo can pretend to be either a keyboard or mouse with pre-existing libraries, costs $25 (again, it's super overkill and that's for a consumer dev board), and also has an onboard largely-driver-free USB-serial interface in case you don't want to use HID for some reason. Go ahead and tell me I'm wrong. But when you plug two USB keyboards or two mice into a box running Winders, OSX or Linux it doesn't discriminate at all. Either and both will work. Unless I'm missing something where it's easy and customary to grab a HID and "jail" it to a specific process/group of processes it would seem you're fighting at an OS level to deal with this.

OK, well that's good. But to begin with, the "club" is supposed to have 4 members and some official organization. I'm guessing you don't have that. If not, I'm willing to pitch in and do up goonclub paperwork/structure/act as president to make it all correct (as long as others want to help as club officers - hell, if someone else wants to be the president I'm good with that I don't care - I've just been down that path a lot with small nonprofits so I know what's up). Then comes an official club roster, for which we would obviously need to have an official membership process and of course membership benefits. I'm thinking some appropriate club artwork/shield/logo could be made by someone on here who is crafty so we can use it on QRZ pages, QSL cards, etc. With a bit of organization we can have a "virtual club" off the ground pretty quick, including some basic software to help net control deal with what will certainly be a disaster of trying to hear people and relay for them (at least to start). The stuff OMISS is using (Netlogger) is pretty good for that, but kinda lame as far as typical ancient windows only ham radio software goes. I'm gonna guess we have enough people with enough relevant skill sets to make this happen reasonably quickly. Of course, that's up to you as sole trustee at this point, fordan.

Do you only care about 10m? If not, some sort of multiband vertical on the house or in the yard would be nice and easy. A dipole of some sort (even multiband would be cheap and nearly invisible if done right. Otherwise for just 10 it depends on what you want to get into. Do you want something directional with a rotator (awesome, but expensive) or do you just want to toss some wire in a tree? Either will work. In fact, both or more than two is a great idea just to futz around with antennas/antenna design/antenna placement. It's likely that the coax from your radio to the antenna will cost you more than a home brew dipole.

SoundMonkey posted:Hello, autists! You're probably going to be best served with a used 100w all mode rig. There are plenty to choose from in that price range. The Chinese stuff is interesting, but low power at this point. All of them are likely to be 12v. Very few are 120, other than old hybrid and tube rigs. Antennas - yes, you can build your own, so the most expensive part is likely to be the coax to get it from your radio to the feed point of the antenna. What do you have to work with for a yard? The easiest/cheapest answer here is: I have lots of tall trees that I can stretch a wire between, and at least two of them are 100 feet or so apart with a spot that I can get the wire up at least 20 feet. Unfortunately, with coax, a power supply and possibly an antenna tuner (depending on whether the radio you get has one built in or not) you're likely to be a couple hundred shy of getting on the air. Unless you have some stuff around to get creative with.

SoundMonkey posted:I can deal with using a switching power supply from a PC as the other dude mentioned, so 12V stuff wouldn't be a big deal. Oddly, coax is the free part, since I have about eighty feet of brand new coax that nobody's gonna need for years. It has N connectors, is there some kind of general standard for certain bands / power levels, or am I just going to need to buy some adapters? What kind of coax (should be printed on the side)? Generally you need to worry about that more in the higher bands, so as long as it's 50 ohm coax you're good, especially at 80 feet. You need the big stuff as you get into VHF/UHF over longer distances. Chances are that your radio will have a PL-259 on it, so you'll need a PL259 female to N male adapter for that side. A commercial HF antenna would also most likely have a PL-259, but if you're building your own just buy an N-male for it and use what's already on your coax. So that means you're a radio, an adapter, a N male, some wire, and some hardware store junk to use as insulators and to hang it away from being on the air. Your budget sounds pretty doable to me with those things in mind. That's exactly what I meant by "unless you have some stuff around to get creative with."

There is nothing at all wrong with using the for HF, but if there comes a time when you need to put up a VHF antenna and need a similar amount of coax and want to save some cash, buying something cheaper and swapping it to the HF antenna would be a reasonable choice.
