Anybody have a recommendation for a decent, but not too expensive dual-band mobile rig? Something I can pop into my Mazda 3 for Skywarn season Otherwise it's off to eham.net to pour over reviews. Edit: Maybe something with a detachable faceplate so I can mount the rest of it in the trunk. manero fucked around with this message at 05:13 on Apr 14, 2012 |

NotHet posted:Does impedance matching matter when receiving only? The first result on google says it is, the second one claims it does not. Of course not... ARRL Handbook posted:If the load is a pure resistance whose value equals the characteristic impedance of the line, the line is said to be matched. To current traveling along the line, such a load at the end of the line acts as though it were still more transmission line of the same characteristic impedance. In a matched transmission line, energy travels outward along the line from the source until it reaches the load, where it is completely absorbed (or radiated if the load is an antenna).

Vir posted:According to this as a code-less Amateur General licensee, you can operate like a Canadian with a Basic Qualification with your US callsign, which should suffice for an HT. They just ask you to state your location in each contact, and follow the Canadian rules and band plan as a Canadian Basic would (>30 MHz, 250 watt DC input power). Aha, thanks! I also found this page which says I also need to add something like /VE6 to the end of my US call.

Is the FT-7900R any good? Reviews on eHam seem relatively positive. Local Ham shop has it at 327.00, comes with an antenna, and it looks like there's a $20 Yaesu rebate right now until Halloween. Is $307 a good deal for this rig? Otherwise, I was considering the Kenwood TM-V71A to throw in my Mazda3 to use for skywarn next spring.

Hummer Driving human being posted:Has anyone been using a software defined radio? In particular, would it be possible to make something like a Raspberry Pi into a fully functional digital 2-way radio? I know as much as SDRs replace a lot of the radio specific hardware with programs that do the same thing but I don't understand what the limits are or what additions need to be make to a normal computer to have it function as a radio. This has been going around lately, it's a cheap TV dongle that you can turn into an SDR: http://sdr.osmocom.org/trac/wiki/rtl-sdr I think one of the latest issues of QST covers it, too.

Vir posted:One of the big advantages of the TH-F6A/F7E is that it actually has single sideband on it. Sure, you can't transmit on HF, but it suddenly becomes feasible to monitor HF while you trek around and don't have your HF station up. I've had my F6A for a number of years and love it. Newer editions of the model come with a slightly higher-capacity battery too. It doesn't have all the fancy data/GPS features of the D72, but it's a great HT. Get this antenna to go with it and you're set: http://www.eham.net/reviews/detail/4298

I've got a TH-F6A that I've had for about 9 years. Bought it in 2004, and I just replaced the battery. I've got a tri-band Maldol antenna to go along with the radio when I bought it. These days, it's looking a little, uh, droopy, when I hold it. I think it took an accidental bend one day. It still seems to work; I don't lose reception or anything, when I wiggle it a bit or the antenna bounces. Is the only way to know for sure to hook it up to a meter and check the SWR? Is it even worth it for an HT antenna?

I FINALLY got the display of my 7900R mounted. My mobile project is almost complete: I'm not super thrilled with the position, since it blocks the glove compartment. I ordered the bracket from ProClipUSA (same manufacturer as the iPhone mount you see up by the air vent). It just wedges between the stereo and the side panel. It was $30.. a bit steep for a piece of plastic. I just need to find a spot for an external speaker, since the rest of the radio is mounted in my trunk.

eddiewalker posted:If you decide you want the face further out of the way, this mount works really well for putting a remote face above a rearview mirror. Still annoyingly pricey, though. Yeah, the mic only plugs into the face, and I don't really like the idea of having the radio up that high. My other option was to maybe just tape the display bracket on the panel that that cigarette lighter is on, but there's no easy access for the cable from the radio body, since it plugs into the back of the display.

movax posted:What's the verdict on test prep books from the likes of ARRL? After putting it off I want to finally sit down, study and jump to Extra in one sitting. I went through the ARRL book to upgrade to General last spring, and I'm using the Gordon West book to study for my Extra this spring. The Gordon West book is basically each question, and the correct answer, and a brief description of the answer. In contrast, the ARRL General book reads more like a textbook, which I think I liked better. The Gordon West book sometimes devolves into "just remember this is the correct answer," which is fine for some people, but it annoys me a bit I really do like to understand the theory behind things. I'll probably keep plowing through with Gordon's book, but if it keeps annoying me once I start taking practice tests, I'll probably supplement with the ARRL Extra book.

So I've got this going on with HRD, my TS590, my laptop and my imac, which is functioning as my external display via mini displayport. It might be a little bit hard to see, but I've got noise at 60hz, and every 60hz after that. It goes away as soon as I unplug from the imac, which leads me to believe the imac's power supply is either malfunctioning, or just noisy and transmitting the noise back up the displayport cable. I tried some ferrite beads on the displayport cable but that didn't help. TS-590S -- USB --> macbook pro -- Displayport --> iMac I'm guessing either replace the imac's power supply, or ditch the imac altogether as an external display? Any other ideas for mitigating this noise?

The only other things I could think of are to try a normal monitor, or temporarily disconnect my station ground and see if that eliminates the loop. Thanks for the suggestion!

Pham Nuwen posted:The ZS6BKW antenna looks pretty good. Does the ladder line need to be vertical as in the diagrams, or can it be run along the side of the house to get it to my posting station? I'm thinking I may be able to stick it up along the side of the house if the ladder line's orientation doesn't matter. The hardware store in town should have everything I need to build it, including insulators for mounting. You could also try a G5RV jr. I've got a long skinny yard and not a ton of room, and I managed to get one up -- I think you need maybe 51 feet or so. It won't tune up on 80, but I've managed to land some awesome dx out in the middle of the Atlantic Ocean. The antenna isn't even up that high, and the legs are definitely not straight. It's by no means the best antenna, but it will definitely get you in the air, and a prebuilt one won't run you that much.

Otherwise drill some holes in a 2x4 cut to length and use it as a window passthrough, with a couple of those female-to-female coax connectors. I think a 5/8" hole is just the right size.

I've started to notice some nasty EMI on 40 and 10 meters. I think I've got two sources of interference. The first is an intermittent, random clicking, which is probably some equipment arcing somewhere nearby. Time to brush up my RDF skills The other is a fairly persistent hum. I've shut off all the power in the house, and I hear both. My question is, could my antenna being roughly the same height and parallel to the power line drop to my house be causing the hum? It's perhaps 20 feet away. Unfortunately the power drop from the pole in my backyard cuts straight through the length of my lot, and my G5RV is in pretty much the only place I can manage an antenna on my lot. The noiseblanker on my radio handles most of the noise, but it's pretty annoying.

Motronic posted:It may not be the cause of these particular issues if they are new, but that's really, really bad antenna placement. The antenna (and power) run north-south through my lot, with the south end lower and closer and the north end higher and further away, but roughly following the height of the power line. I may try dropping the north end and shooting for an inverted vee. I'd love to put something on my roof but it's pitched pretty steeply, and the guy who owned my house in the 80's actually fell off it and died

I didn't notice any performance hit to the antenna and when I decided to just drill a hole, the film peeled right off with no paint damage after two years of mag mount use. I think the January QST had a thing about this. The trick was to apply a bumper sticker to the magnet side, and then trim around the base of the magnet.
