The fundamental idea of the NPR test is a VERY good one -- properly done, NOT with a sliding reference level, is to expose the contribution of spurs and phase noise. It is the "sliding reference leve
The fundamental problem is that the guys in PY, LU, CX, and CE have the same competitive disadvantage by virtue of their location with respect to population centers as do we on the west coast of the
1) Let's separate high and low power 2) Lets separate assisted operation 3) Lets separate when more than one person operates, or more than one transmitter. 4) Let's divide up results by geographical
Hogwash. Look at numbers by ZONE. Contesters in non-competitive zones vote with their feet. And CQWW is the dumbest contest in terms of operating skill -- for the vast majority of QSOs, if you get th

Horse-pucky! Scoring rules determine who wants to work whom. For stations in Zones 3, 11, 12, 13, 29, 30 to have fun in a DX contest, there must be a real desire for other stations to work them. Thos

The rules designed by N6TR for Stew Perry allows 4X for working a QRP station and 2X for a Low Power station. I think that's a very good rule. I work QRP in some contests, and the many of guys that h
If you are PVRC, YCCC, FRC, FCG, NCCC, etc. and have been submitting scores for 20 years or more to the SAME club, why should you have to submit scores to a club in a new area to which you have no al
So sad to lose a great operator like Rich. But for the Grace of God I might have joined him -- a few months ago, my primary care doc heard a murmur on my heart, and sent me for a check up. Long story
I'm retired from a career in pro audio, so own at least a half dozen different headphones. My favorites for CW and RTTY are CM500 and Sony MDR-7506 -- I find them equally comfortable, they sound equa
No, but it's an electret mic, and like all electret mics, does need DC bias. A "battery box" comes with it. Or can it be powered from a rig like the Icom? Yes, 5K resistor (value not critical) from V
As a ham trying to help you solve your problem, I'll ask WHY you can't use LOTW? It's nearly free. The only requirement is that you must somehow enter QSO data into electronic form. There are many go
WRONG. Those high rates simply show well equipped stations with good operators who, by virtue of their LOCATIONS and the SCORING RULES, are really IN the contest. 73, Jim K9YC _______________________
Yes, these "variable frequency drives" (VFD) use modulated square waves to control the speed of motors, and are well known to be MAJOR generators of RF noise. I first became aware of them about 20 ye
It isn't about ME, Hans, it's about the thousands of contesters outside the favored geography, many of them my neighbors. It isn't even about winning, but rather simply about being in the contest or
Remember that every pass through BlueTooth adds A/D and D/A conversions, which add latency. This applies to both RX and TX signals if both use BlueTooth. WiFi and Ethernet paths have the same issue.

Human tolerance of delay is VERY dependent on the application. With AUDIO, an echo greater than about 35 msec becomes increasingly problematic; even delays as short at 30 msec can be fatiguing. Incre
There's something quite fishy about the description. First, a couple of definitions. An omni-directional mic picks up sound more or less uniformly from all directions. A uni-directional mic favors a
