It was great to hear A45XR and A92IO with strong signals into the NE USA last night in relatively quiet condx around their sunrise. A92IO's signal popped up at least 2-3 s units in a 10 minute span.
I use 450 ohm window line in upstate New York and it's done just fine through 10 winters here. You don't need to slope the ends - performance is independent of how quickly you bring the wire ends dow
The antenna efficiency will improve as you add more elevated radials beyond just 4. Eight to fifteen feet of feedpoint elevation isn't sufficient to reach theoretical efficiency with just 4 elevated
West coast stand outs here on Friday night through the dismal codx were K7OX and VE6BBP. 73, Barry N1EU _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
Herb, is there any chance that was IK0HBN you worked? 73, Barry N1EU _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
Sure condx are generally down. But then there's a morning like Dec 14. I never heard HL in all of 2008-2009. 73, Barry N1EU _______________________________________________ UR RST IS ... ... ..9 QSB Q
The best omnidirectional "RUN" setup for 160M is using a transceiver with dual high performance receivers in stereo diversity so you can listen with two antennas simultaneously. I've used both the K3
I had the tape running this morning around 1100Z as I scanned the band and I caught 49 stations, and I posted the sound clip to http://n1eu.com/mp3/cq160ssb26Feb12_1100Z.mp3 That's what it sounded li
As far as I'm concerned, the main objective would be to limit AGC action. Depending on the radio, this might mean turning down RF Gain/turning up AF Gain, increasing AGC Threshold, or turning off AGC
Sorry for yet another plea for help identifying an interference source. Please see the video/audio I just uploaded to http://youtu.be/AN9VNCanEJM The panadapter clearly shows wideband rhythmic interf
like a street light issue but still no hunch on what it could be. 73, Barry N1EU _________________ Topband Reflector Archives - http://www.contesting.com/_topband
The noise occurs early AM, before sunrise. It was gone during the day and early evening yesterday. I made a new recording this morning and the rhythmic nature of the noise pulsation is very evident:
I've had many helpful private emails from folks who've seen/listened to what I posted. An RFI occurrence may or may not have a characteristic fingerprint, but you're not going to know unless you ask
I recorded the bulk of the contest, as heard in stereo diversity through my Orion II plus RX366 subreceiver into 580ft long Beverages. If anyone who worked me would like a soundclip of their signal,
I thought I'd share some data points from my Stew Perry log. Even though propagation to the west coast seemed good from upstate NY, I had the impression of less activity than expected from California
I love that slow drift. Frequency stability is boring and overrated! 73 & Happy New Year, Barry N1EU _________________ Topband Reflector Archives - http://www.contesting.com/_topband
Google seems to indicate that they don't ban CFL bulbs in Green Banks WV, but maybe they should. 73, Barry N1EU _________________ Topband Reflector Archives - http://www.contesting.com/_topband
I was an early adopter of the K3 and installed all the hardware audio updates as they were released. I'm picky about audio and the K3 ssb rx audio was quite good. At http://n1eu.com/K3/K3_notes.htm y
Steve, unfortunately the latest firmware/software hasn't addressed the cw RECEIVE latency (I measured 160msec) which has always been the more significant cw issue. There are no current plans to addre
I applaud K7FL for sponsoring the Top Score 100% Search/Pounce plaque. Such an award should be available in EVERY major contest. 73, Barry N1EU _________________ Topband Reflector Archives - http://w
