Start by turning off all power to your house. If that fixes it, turn on one cricuit at a time until you find the noise maker. Othewise, it's either in your radio, or it's time to discover the joy of radio direction finding as you hunt down the source. You have a Kenwood TS-570S, right? I haven't heard complaints about that radio myself. Edit: Wait a minute, have you tried switching to AM or FM mode? We get a bit of illegal CB operation in the 10 meter band.

Random question: Does anyone know where I might be able to find a used replacement for my VX-8R's factory rubber duck antenna? I had that and a Diamond SRH940 for it and somehow managed to lose both of them over the last couple of months. Don't know if there's a preferred forum or site for that sort of thing or what.

Gonna assume the 8r is a SMA like most. I got a decent one off ebay for my FT-60 awhile back. Gigaparts would be a likely spot to look. The below is similar to the one i have. http://www.ebay.com/itm/New-Nagoya-...=item4608e42fa6

I'll try the electrical thing, my house is certainly noisy with all my computers and the wifi. I used to get the same thing at my old place, a condo where I kept the radio pretty far from other electrical stuff. Would trying it without the antenna plugged in help? I should also try separating it better from the power supply. Seems like I always need to run the coax past the power supply...

So the normal amateur radio is a half-duplex, single channel radio (with the exception of the dual/quad bands with cross band repeat which would allow full duplex communication). Are there any amateur programs out there are act as a trunking system (if I understand trunking correctly) wherein a piece of software will find an available frequency in the correct band and through DTMF or some other selective calling feature be transmitted to specific radios? I know that part of ham radio is transparency and not having anything going on outside of the public ear but is there some type of system that "finds" the other radio you're looking for as opposed to pre-arranging a frequency to contact someone on? I'm sure I'm getting something wrong here so feel free to correct me.

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. Edit: hamradio.com has it for 285 or so after rebate, hmm... http://www.hamradio.com/detail.cfm?pid=H0-010079 manero fucked around with this message at 02:11 on Oct 25, 2012 |

The Hurricane Watch Net is going to activate again for testing purposes tonight in anticipation of Sandy hitting the continental US.quote:The Hurricane Watch Net plans to active today, Sunday, October 28th at 5:00 PM EDT (2100 UTC) on our net frequency 14.325.00 MHz, as well as 7.268 MHz and 3.950 Mhz. Our plans are to line up reporting stations in advance of our Monday and Tuesday net activations. During our Sunday activation, we will welcome EMA's, EOC's, and other official government stations, as well as Red Cross Centers, Salvation Army Shelters, and other Emergency Shelters, to check their HF equipment in preparation for Sandy's arrival. Hummer Driving human being posted:Are there any amateur programs out there are act as a trunking system (if I understand trunking correctly) wherein a piece of software will find an available frequency in the correct band and through DTMF or some other selective calling feature be transmitted to specific radios? I don't think there's a proper DSC frequency for analog talk in the amateur service, like there is in the maritime VHF service. I think it's both legally and technically possible to do it, but amateur radio is not really supposed to be like a phone service. Maritime VHF DSC is mostly for setting up routine business calls, or for emergency alerting. Amateur radio is more like the days of party lines and continuous monitoring of calling channels. [Edit: I forgot about HFlink - there's actually an active system of DSC that they call ALE on HF. It has some differences to marine DSC or VHF/UHF trunking though.] There's something called Digital Code Squelch (the same as Digital Private Line®), which is sort of an advancement of regular repeater tones. If you agree on who sets their radios to which code, you can set your radio to monitor a simplex frequency or scan list, and it will only break squelch when the tone is received. It's not like Digital Selective Calling though, in that it doesn't target an individual recipient and it doesn't include a "working frequency" that you QSY to handle the data. Yaesu has something they call "EPCS" where you can cause a particular HT to ring on the reception of a pair of repeater tones. I don't think it's widely used.

The Hurricane Watch Net is most exciting when a hurricane passes the Carribean really, since those guys typically have no other way to report the weather once phones and internet goes down. When it's over the continental US, I'd bet the local repeaters are have more local information - Skywarn, shelter traffic etc. In Long Island they have a D-Star network with the repeaters paid for by a government grant.

Check here: http://skywarn.org/skywarn-training/ The local National Weather Service people listed there hold annual training classes for learning how to accurately report the weather, as well as weather safety and traffic safety. Those classes are mandatory for being considered a "trained spotter". They don't encourage storm chasing by the way, just observing from safety.

Gosh, where do I start. I realized that I enjoy listening more than I enjoy talking, and especially over the past four years, the airwaves have generally gotten a lot more racist and angry, and I don't have anything that I want to talk about with people like that. I don't have anything in common with the 60+ gout crowd, and I'm in my early 30s with no kids so it would be creepy for me to do the "elmer teenagers and teach them about radio" thing. I kept trying to gravitate towards the techier side, the guys that are into radio but not all MY SPARK GAP TRANSMITTER, the ones that like new tech - but 30 meters really just breaks down to a slow chatroom where people have macro'd conversations. And VHF/UHF digital guys are just obsessed with APRS, which I could care less about. I was really into satellite for a while, but that's even more low-content. Technologically it's pretty neat, but once you've made a dozen contacts on the LEO sats, there isn't really much more excitement other than trying to fill out a grid square map. Plus, satellite guys are starting to get into black-box junk like "lol, let's put this android phone in a cubesat!" which kind of grates on me. I will definitely get back into radio if the FCC starts enforcing more especially on 75 and 40 meters, or if we get a HEO sat like ol' OSCAR 13. I sadly don't think that's ever going to happen, though. I'm going to pack the HF rig and a 2 meter mobile away, and sell everything else. I've put in my 21 years, done all that I can do on a shoestring budget without 10 acres of hilltop, and am ready to move on full-time to embedded and digital development and tinkering.

The only things down here that seem to be moving is DSTAR, but I can't afford to even look at those radios. I'm determined to get my General as soon as I can get something other than a used 2M rig. Maybe I'll have more fun once I can talk out of the county? (Anybody looking to "throw away" a radio to a grateful goon?)

I haven't been licensed long but, I am sort of in the same situation, I went out and bought equipment, and I can't really operate from at an apartment, although I've drat well tried. I'm more into computers and tech than electronics, and that's one thing I find difficult with this hobby. I don't want to talk about radios while I'm on the radio, and the guys that are on the radio, well, many of them have poor social skills. There's some politics driven discussion, that's about it. The racist stuff comes out in person, but, where I grew up and where I am now, much of it isn't so much racism as they're just in neighborhoods that have gone to poo poo, and don't like what they see. I didn't grow up there so I can't really talk about that on the radio either. For my piece, I've been working with a local club on their repeater system and learning how that all works. I have added an Allstar Link node, and an Echolink node. Now I've run into the IRLP/"It's Radio" crowd while getting into it. People are very opinionated in this hobby, and they let that show. I've kinda stopped putting up with the guff and pointless comments. I'm supposed to give a presentation tomorrow at our club's membership meeting RE: our repeater, and where we'd like to go as a club, and I fully expect a bunch of blank stares and emails later about how "ham radio is dead" or "We don't need computers". Since I'm not made of money and sort of live this hobby through the club, that's discouraging. [quote="angrytech"]2m[/angrytech] If 2 meters is alive where you are, you can grab Chinese HT for anywhere between $50 and $100. Maybe less if you run into people who bought them and don't have the patience to get into it. 2m mobiles are getting pretty cheap, but, people often don't let them go at hamfests cheap enough considering you don't know what they've been through and what new VHF radios can go for nowadays. As for a base though, height is might with VHF, so if you're not going to get the antenna up anyways, before you get all into it and get disappointed I would grab the HT and go. You can always turn it into a APRS tracker or learn Chinese from it later. E: Also! 290, etc, what happened to AG0ON? We can still revive the net. I can RF it on my side with my repeater, we can certainly try and get as many 2M goons either setup with how to do an echolink/allstar node , or help find an enabled repeater. If we can get that going we could just make it whitelist/conf and have a ham echolink chat for goons only, but on radio.

Hey I like Newsline. I listen to the podcast every week. Playing it on the repeater should hopefully stimulate some interesting discussion, but I guess it depends on where you are. 290, don't let your license lapse. Especially those microwave frequencies might become handy when you play around with embedded stuff. One of the things I had looked forward to was using a Pacsat BBS - a BBS on a satellite. Last I checked there aren't any that work properly right now, but there's at least one Australian and one Norwegian cube sat in development that are supposted to have Pacsat BBS on board. Hopefully they're not getting up on the ISS, because that gives them a too low inclination to use here in the north.

I had that same problem. I went from nothing to extra in one test session, got a radio that I could use in my apartment, and then the disappointment began. Everyone was easily more than twice my age and things tended a bit racist. I tried to be a good sport and hang out, but when they wanted to go get Steak n' Shake for dinner at 4:30pm, they were too close to a caricature of themselves.Partycat posted:I'm more into computers and tech than electronics, and that's one thing I find difficult with this hobby.

I haven't used my own voice to talk to others on my radios for nearly 3 years now. I picked up a SignaLink USB and a USB-to-serial cable to control my radio and have used PSK31, RTTY and JT65 to talk to people as far east as the US east coast, as far south as Cuba (though I've HEARD people from South America), as far north as Alaska, as far west as Russia and tons of places in between. I'm in Portland, OR, my radio only puts out 5 Watts, my antenna is a piece of wire strung up 6ft above my ground-level porch, and I'm restricted to the 10m band because I only have a Tech license. I've been very impressed. With a proper antenna, a few more Watts and a license that lets me use the other bands, I'd never run out of signals to respond to and none of them want to talk for 45 minutes about "putting the White back in the White House" or anything.

I have some old antennas my grandpa gave me for VHF, UHF and so on use, I need to find mounting brackets for them, so I wonder if anyone here can tell me what they're called and possibly who supplies them? First is this:  It's an Allgon brand antenna, I have a couple of them for 2m and NMT 450 MHz. The screw mount is similar to some eBay brand magnetic mount antennas but much thicker. I measured the internal diameter at 4.7 mm, so the screws are probably 4.5 mm or 5 mm.  The other is this, which is similar to some old AM car antenna mounts I remember seeing once, inner diameter around 7 mm, one of them had a wing-nut attached that was 6 mm so it probably screws into that. Outer diameter of the ring is 2 cm. The antennas are apparently from a danish company called Scan Antennas. I'd prefer to buy on eBay or another site that offers cheap shipping to Norway.

Slight update: I got a thoroughly unexpected raise at work, and there's much less crunch to unload my gear. I'm going to give the IC-271 and IC-475 a good thorough cleaning, box them up and sit on them for a while. In a year to two, I will be in the Denver area and hopefully should be in a slightly more interesting VHF/UHF environment. Still QRT, but less bitter after chewing on it for a bit.

The greybeards inform me that the second picture I posted is called a DV mount. I'm still studying for my exam, I was thinking a quiz with the Q-codes might be helpful, so for example it would show QRM and ask me what it means in a multiple choice fashion. Does anyone know of a quiz like that? If not I'll have to write my own like I did to learn the phonetic alphabet.
