Well...my experience is that with a dipole on 20m all you need is 25w to work anyone. I have worked many at 10w and an outside dipole. With my K3/10 my max power out is 16w carrier and having no problems doing psk-31 using a HighGain TH3mk4 triband beam. IMHO running above 25w on psk-31 is unnecessary (on 20m). I can not provide an opinion for other bands as all my psk-31 has been on 20m.
However, I will soon be running psk-31 on 600m running up to 80wn (ERP~3w). 73, Ed - KL7UW WD2XSH/45 ------------------------------ Message: 17 Date: Tue, 11 May 2010 15:46:09 -0400 From: "Tom W8JI" <w...@w8ji.com> Subject: Re: [Elecraft] Calling CQ on PSK-31 To: "Elecraft" <elecraft@mailman.qth.net>, "Frank MacDonell" <kd8...@gmail.com> Message-ID: <4304e524f84a4bffbaf21d6e44788...@radioroom> Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original Frank, There are multiple reasons you are not getting a response. While it is true PSK is only a few dB better than CW under ideal conditions, some tend to pretend PSK is magical and very low ERP will work wonders. Unfortunately very weak signals are still very weak signals. They will just be buried in the noise on the other station's display. Even if they are printable when found, no one will see you. Length of CQ is especially a factor when a signal is really weak. It's kind of like a world where everyone is equal and held to the same low level, except with 5 watts and an indoor antenna you are probably among the lowest of the equally weak signals. You just won't stand out at all. CQing is not the way to go when the signal is barely above noise. Have fun calling people, that will be the best way with an indoor antenna and 5 watts. CQing will be frustrating. 73 Tom 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-600w, 432-100w, 1296-60w, 3400-fall 2010 DUBUS Magazine USA Rep dubus...@hotmail.com ====================================== ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
