    Thanks. Youtube made a change. All URLs require https instead of http, so that obsoletes many of the links.

    Hi, good comments poeple need to understand that there is more to communications than the Internet, and in the case of ham-radio, you can build good equipment that really can perform well. FYI, tonites Mars Recon Orbiter reception was very good, its just over 52 million miles and coming in strong.regardsPaul(www.uhf-satcom.com contributor)

    Yes. PSK-31 is a 100% duty cycle mode while transmitting. Note that you should back off of full power for other reasons too. Backing off to less power makes your transmitter more linear, resulting in a cleaner signal. Also PSK-31 does well with low power; 25 watts is plenty most of the time. 73, Dave

    Thanks for the excellent instructional videos. I can see that you have gone to a lot of trouble putting together well-produced and informative pieces. Kudos and many thanks. I am a brand new ham, just passed my Technician and using your General series to prepare for that test. I still have to decide which part of the hobby I want to embrace. At present my interest is in emergency communications.
