This sounds very likely, especially as the interference disappeared by 1AM. Some time ago I had really bad interference on the band, and I roundly cursed the unknown individual responsible for it. Th
Steve, Have you considered the software defined radios, like the new Flex-5000A, or the older SDR-1000? http://www.flex-radio.com/ Cost-wise they compare well with the top-of-the-range legacy radios
Tree, when the radio goes into production, will users be able to download and install further DSP updates, or will they be stuck with the version they get when they buy the radio? (In the back of my
I'm contemplating buying an AIM4170 plus a USB adapter to help with top band antenna experimentation. Does anyone here use that hardware combination? I heard that some people have had difficulties ar
Thanks everyone (on this list and by private email) for your comments. Looks like my VISA card will get flexed very soon! -- 73 Ian, G3NRW _______________________________________________ Topband mail
Hello all, I managed to get hold of 4 reels of thick copper wire (plastic insulated, normally used for domestic power wiring) and plan to bury them in the lawn. Each reel is 100m (~325 feet) long, an
Kevin, Many thanks. And to the *many* other people who sent me private emails with their detailed views and offers of help, please accept this post as a general thank you! All very much appreciated,
As a matter of interest, what was the make and model number of the modems that people here have had problems with? -- 73 Ian, G3NRW _______________________________________________ Topband mailing lis
Hi Joe, This looks *very* interesting! Quick question: Where is the WSPRnet page? -- 73 Ian, G3NRW _______________________________________________ Topband mailing list Topband@contesting.com http://l
Hi Rune, Chicken wire should be all right, but make sure the holes are not too big, otherwise the chickens will get out ... (Sorry, I couldn't resist that! I hope you get some more sensible answers :
John, I regularly hear something like this in mid Beds, all over the band, but particularly around 1949kHz. It is usually S9+40 or more, making the band unusable for hours at a time. At first I thoug
Until recently, interest in PropNET has concentrated on reporting propagation on 30m, 17m, 10m and 6m. However, popular focus has shifted to 160m in the past couple of weeks, and some pretty interest
Len, The signal on 1830kHz is quite strong (S5) here at the moment (1535z). No breaks in transmission heard for the last half hour or so. A (very approximate) bearing is 30/210 degrees from here (51°
I can put up about 110 feet of wire for topband, and am toying with the idea of a loaded dipole, a la: http://www.k7mem.com/Electronic_Notebook/antennas/shortant.html As a starting point, I am thinki
[Snip] Many thanks to everyone here and off-list who replied. Very helpful inputs. I realize I should have said that my main interest is NVIS, rather than DX. As for having a full-size dipole at 120
Mike, Looking at the response of the 402/402x filter, I really wonder if it works as good as it looks. The response appears to be flat down to about 1.7MHz, then it turns the corner and falls off a c
Hi Rick, If your antenna is within wifi range of your shack, you could try running the laptop to remotely control the AIM4170, which remains in the shack. Full details here: <http://homepage.ntlworld

Top band was my first band of choice, right from when I was licensed over 50 years ago. After a long break I am now planning to get back on the band this winter, to try to work some CW DX, but I'm su
Hi Herb I think you will have more success if you ask for their LOC -- the Maidenhead "LOC"ator. -- 73 Ian, G3NRW _______________________________________________ "160-meters is a band for men, not fo
