Dave has a real point here. Plus, I add anyway on HF, for horizontal antennas the vertical pattern is rather wide. And, the need to adjust the height of the antenna is several meters in order to get
... Correct for fully functioning and tuned amplifier. In case a glitch happens or when tuning the amp, the harmonic emission level may exceed the presented figures. Likely more than 20dB yes. It sav
Some work with luck .. usually not for more than a contest or two. Then they realize they need to design the station and use the station to the specifications they created. Making a station capable o
Now this gets very interesting ! Correct. That is, what Ton wrote earlier about, was the harmonic. But a multi-radio station cannot rely only on harmonic design. The fundamental frequency cannot exac
Cool if you used one coax for all three 800W radios .. did you ? Even such triplexers can be done with careful design and then pruning the Farads, Henrys and walls in the box. I think there was a 100
Hi, Tom has many things correct. As a summary: there is current flowing through filter components when there is stopband energy trying to enter the filter. It creates heat and thus components failure
Regarding RBN, I thought there is a no-statement on internet. Anyway, for a single op, decoding assistance is not allowed. That may be human or technical of origin .. the idea is the operator does al

... ... In my systems the 40m signal entering 15m is attenuated by band filters. Even ICE with old school micas is OK, after which FT1000MPs survive no problem. I use always band filters if I have m
Excellent ! This tells two things: Despite what has been written here recently, there still are DX who know what they are doing with the round knobs they have sticking outta the box with a fan and co

Just an idea for humans, RBN and clusters for quickly communicating some chaos management split on CW. At least I will be transmitting upr2 next CQWW CW when I want people to call about 0.2kHz up. Or
OK .. hei there .. Engineers! Scientists ! Optimize ! Case: a multiplier with a pileup in CQWW SSB 2012 .. any band 160-10. My suggestion is to start thinking about a scenario the DX is buried under

.. I had a chat about this with Harry or Vlad. The reason is you hear what the other station sends. If he sends a strange variation of S56A it is _your_ responsibility to get it right. That is, you a
There are many possible flaws with these. Some times it happens so making the wires has gone unshielded and straight wires. Then just twisting the cables together may fix the EMI problems. Not making
I was expecting someone to point out the final truth about shooting fish in the barrel. It cannot be done. Not even with aiming assistance. Not even with assistance and an over powered rifle. Not eve
Adding digital information to assist the other station to decode your call is not SSB. In case this kind of technology would surface (and it would be allowed), many contests would need a new entry ca
Chris, You set a completely new ball up in the air. You set a claim contesting is not a sport. Can you please elaborate a little? -not a sport on mental side ? -not a sport on physical side ? -no fat
Thanks Chris. I see your point. For many of us this is sport as the self-regulation works. Most of us realize there are participants who do not care so much for the rules. How about .. if you compare
