My horrible utility line noise (which afflicted me in ARRL 160) continues and I'm looking to operate in the CQ 160 test this weekend and not be an alligator. I've located the offending pole but lack
Rick, there are irregularities in my noise - and in the previous utility line noises I've had at my QTH - that prevent any predict-the-exact-time-of-the-noise-spike-in-advance algorithms. Although my
AS AN UPDATE, N2NC and I are in communications regarding his Linrad noise blanker settings and I am making some progress in learning how to effectively adjust and operate the advanced noise blanker c
A side note on the subject line... All nine major CQ contests (including 160, VHF, and WPX) have official names starting with CQ World Wide. Even the three WPX contests have official names starting C
There are "equipment de-installers" that salvage different size/color hunks of Teflon/Tefzel wire from their day jobs and sell the pieces on E-bay at what hams would consider reasonable prices. Lengt
I don't know about Tesla Powerwall in specific. And I don't know if you are asking about solar-charged (as opposed to grid-charged) Tesla Powerwall but likely you are. Wiring solar panels to inverter
Tony, I have abused BN-73-202 cores at the 100W level when I accidentally transmit into the receive antenna through the transformer. I have smoked the termination resistor but never damaged the trans
I think I was the one who first suggested Wednesday night aka Thursday morning UTC, because the CWOps 0300z session wraps up at 0400z after which I prowl around 160 a bit looking for EU DX. I know th
I saw some news about JA frequency/mode allocations changing in the past year and seem to recall new frequencies available for data and phone. For plain old 160 Meter CW - is the JA Window still 1.81
Also as I review this years ARRL 160M rules... An earlier version of the rules (current in 2012) here http://www.arrl.org/files/file/Contest%20Rules%20PDFs/2012/2012-160M-Rules-V2.pdf says "6.1 The s
I think the 1.830-1.835 rule had been removed and reinstated at least once before (maybe back in the 90's?). While the ARRL contest portal is great, I'm not sure where to find archived copies of rule
George, in ARRL 160 the DX would *only* be looking for W/VE if CQing during the contest. So the DX Window concept has some value (if anyone ever respected it which they didnt). This is a fundamental
Unless you are in some incredibly-low-atmospheric-noise location, the rig's preamplifier will be enough for a K9AY loop. It is important to use good coax with intact shield. I was helping a friend of
Last night was great! I only was on for a half hour at 0400z (after the 0300 CWT) and worked 8 Europeans. Judging by on air rates and reversebeacon queries, US Midwest stations were having even more
Conductivity of Copper: 5.85 x 10^7 mho/m Conductivity of 301 Stainless: 0.14 x 10^ mho/m Stainless is 42 times worse conductor than copper. Larry, was the band clamp holding a copper conductor onto
Roger, I have gone through the school of hard knocks on alligator clips, especially as my home station went from 100W to making major efforts at legal limit RTTY contests. While the BU-27C end serrat
NO3M has done some truly top-notch work with tube transmitters and I've worked him using several of his "vintage homebrew" rigs on 160M. They are BEAUTIFUL ! Check out some pics: http://no3m.net/vint
Pete, I live in a residential neighborhood (not the most dense by any means), and all my receive antennas will point towards my house or a nearby neighbor's house. There are certainly buzzes and whin
Yes! Signals from EU were huge on 160 for many hours both nights. I had to peer at my radio dial a few times just to be sure I wasn't accidentally on 80 or something. 80 was great too. How far west i
Roger, from my location in W3, I enjoyed a truly spectacular opening to Europe at your sunrise in Russian DX Contest last night. I had a good amount of QRN from spring storms in NA, but the EU signal
