I had a few hours free yesterday afternoon, so I began the dual 80/160 radiator inv. L project. In the process, I found that water had entered the coaxial center insulator that was used at the feedpo
I did not use a switch. They are both permanently connected at the feedpoint. 73 Art NK8X _________________ Topband Reflector Archives - http://www.contesting.com/_topband
I took a hint from Luis HC1PF. A small 1.8+/- clock oscillator and a wire attached to a pole is what he used. I found said oscillator on eBay. It worked, but I am not sure the near field results shou
This is a difficult problem. The neighbors might object to an anechoic chamber around their house. I'd guess the best solution would be to get a HWF up as high as possible, That isn't possible here a
A similar method has been in use here for a couple years. It let me snag VP8STI among others underneath a big noise last winter. This year, I made a wire flag for 80/160 as a noise pickup antenna, an
Conditions to EU were better than I have seen so far this season I was only on from 0430-0500z, but even that was impressive. Tom 4O/KC0W was very loud. In fact, he was louder than he is at our sunse
It is ironic to see AT&T's filings, since their uVerse product is responsible for quite an increase in the noise floor on HF. Art NK8X _________________ Topband Reflector Archives - http://www.contes
There are numerous reports on the web from hams experiencing RFI from and to Uverse. My main point is AT&T was complaining about receiving RFI, without keeping their own house clean. 73, Art NK8X ___
Perhaps the 3801 isn't the only equipment being used. A quick search found this posting from three months ago. It references the AT&T 5268AC router. It appears to be made by Arris. This seems to be a
I noticed the band noise was up a bit last night. I assumed it was due to the known sources in this area. i.e. neighbors houses, and trees touching AC distribution lines. This morning, I rewired the
I noticed a few weak echoes this morning around 0400. I thought it was someone playing around. Art NK8X _________________ Topband Reflector Archives - http://www.contesting.com/_topband
I am wondering if there is a backscatter type condition that can also slow down the Vp. Art NK8X _________________ Topband Reflector Archives - http://www.contesting.com/_topband
Out of boredom this afternoon, (not a big SSB fan) I created a poll to figure out if there are better and worse frequencies for DX-peditions on Top Band. The survey is at the top of my otherwise unre
I received requests to extend the frequency range of the poll lower, to include fishing beacons etc. There is now a second poll that covers 1810-1819.5 http://nk8x.net/TB.htm 73, Art NK8X __________
