Hello Jim, In major part I agree with your suggested method for tuning up and amp, but I would never begin my tuning with an output from my transceiver of 4 watts. I have never heard of anyone suggesting that tuning should begin with anything close to 4 watts. I generally go thru 3 or 4 steps, but I start with my transceiver set to about 25 or 30 watts output. I bring my drive up in say 3 or 4 increments until I reach my desired amp output, usually in the range of about 60 or 70 watts of drive, at least for smaller amps. However, when I tune up my Henry 5K I don't exceed about 45 watts of drive because I would already be over 1500 watts out. At 70 watts of drive I would be running over 3KW, or 3.5 KW on 40 or 75 meters.

I don't use "tune" unless I am using the internal tuner. Set your tune power setting to 4 watts, place your amp in standby, press xmit (xmit only, not tune) get your tuner properly adjusted, press xmit to release, turn your power output down to 4 watts, enable your amplifier, place your radio in CW mode, tune to a frequency CLOSE to where you want to transmit - NOT on top of other QSOs, use your CW key to cause the radio to transmit, tune your amplifier and refine your tuner settings, let off the key every few seconds to not heat up everything, if your are happy with the current settings, increase your power out slowly as you watch it on each increase until you have achieved the output power you are looking for. 1 lower your output power 2 Transmit only a few seconds at a time 3 Find an unused frequency - close is plenty good 4 Tune with your radio without any amp 5 When happy, enable the amp 6 Adjust settings 7 Increase power slowly 8 Readjust if necessary. 9 Tune to your target frequency 73, Jim ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] _____ If you reply to this email, your message will be added to the discussion below: http://elecraft.365791.n2.nabble.com/Tuning-your-radio-and-amplifier-to-your -amtenna-tp7592596.html To unsubscribe from Elecraft, click here <http://elecraft.365791.n2.nabble.com/template/NamlServlet.jtp?macro=unsubsc ribe_by_code&node=365791&code=a2Q3Z2NAcS5jb218MzY1NzkxfDE3MzQ0NDk4ODY=> . <http://elecraft.365791.n2.nabble.com/template/NamlServlet.jtp?macro=macro_v iewer&id=instant_html%21nabble%3Aemail.naml&base=nabble.naml.namespaces.Basi cNamespace-nabble.view.web.template.NabbleNamespace-nabble.view.web.template .NodeNamespace&breadcrumbs=notify_subscribers%21nabble%3Aemail.naml-instant_ emails%21nabble%3Aemail.naml-send_instant_email%21nabble%3Aemail.naml> NAML -- View this message in context: http://elecraft.365791.n2.nabble.com/Tuning-your-radio-and-amplifier-to-your-amtenna-tp7592596p7592600.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
