Topband: electromagnetic effects on space weather
I wonder how much effect contest weekends have https://arxiv.org/pdf/1611.03390.pdf _ Topband Reflector Archives - http://www.contesting.com/_topband
Re: Topband: Top Band and JT65
>>>To me, just not the challenge of dxing mostly cw and ssb. Fair enough. There is absolutely nothing wrong with that. Another angle. I find JT65 to be a very relaxing mode. Which other mode allows one to read and write emails, go get a coffee, answer 'nature's call', etc. while making contacts? Timing is important, but doable. :^) 73 de Vince, VA3VF _ Topband Reflector Archives - http://www.contesting.com/_topband

>>10 Watts is considered high power on the digital modes. Is using 1000 >>Watts on 160m (+20dB) and 250Hz receive filters (+10dB) on both ends >>of a CW QSO more challenging than 10W on JT65 on the same link? >>Perhaps not. JT modes are weak signal modes, not necessarily low power/QRP modes. The power needed on 160 will likely be higher than on 20, for example. The benefit is that, mode by mode, JT can do more with less power. The old FCC rule/reccomendation about using only the power required to complete de QSO still applies. :^) 73 de Vince, VA3VF _ Topband Reflector Archives - http://www.contesting.com/_topband

JC, >>I just don't like JT modes. I'm way behind reading messages. Please disregard my last one. As we say in our mother tongue 'gosto nao se discute'. :^)) 73 de Vince, VA3VF _ Topband Reflector Archives - http://www.contesting.com/_topband

Re: Topband: Top Band and JT65
>>>Maybe JT65 is too young to have good statistics, but how many DXCC >>>entities have ever been activated on JT65 on 160M? It'll never reach the levels of SSB/CW/RTTY, if that's what you are getting to, for the simple reason that DXpeditions to rare places would be crazy to spend precious time on a 6 minutes per QSO mode, assuming there is no repeat. 73 de Vince, VA3VF _ Topband Reflector Archives - http://www.contesting.com/_topband
Re: Topband: Top Band and JT65
I did JT65 on 160, but really what´s the challenge? Is amazing when you did a CW qso, switching between RX antennas, filters and radio adjustments to pull out a callsign I don´t know what people than been on topband for decades feel about that 73. Jorge CX6VM/CW5W = Jorge, Is not a question of 'challenge', it's a question of being able to operate on 160, with a station that won't cut even on CW. The same applies to VHF/UHF when it comes to JT modes. Let's not forget also that many aspiring topbanders do not operate on CW -not trying to create a CW yes/no thread - and CW, before the JT modes, was the best mode for topband. And finally, people with hearing problems. 73 de Vince, VA3VF _ Topband Reflector Archives - http://www.contesting.com/_topband
Topband: Top Band and JT65
>>>I cannot understand why JT9 is used so little on 160 thru 20. JT65 >>>is a VHF mode. Not really, there are different 'flavours' of JT65, on HF it's JT65A. As for JT9, there reason is that JT65-HF, and its derivatives, such as the one maintained by HB9HQX, is still used by a substantial number of people. JT65-HF does not support JT9. 73 de Vince, VA3VF _ Topband Reflector Archives - http://www.contesting.com/_topband
