Utility / Re: WWV announcement of military exercise?
« on: April 10, 2020, 1041 UTC »
The US Department of Defense (DOD) plans to start making use of a provisional time slot on WWV and WWVH to announce upcoming HF military communication exercises and how the Amateur Radio community can become involved in them. The announcements will occur at 10 minutes past on WWV and at 50 minutes past on WWVH. WWV and WWVH transmit on 2.5, 5, 10, 15, and 20 MHz.

I recently saw a K1 in good condition that had two bandmodules (80/40 and 40/20)
and a built-in ATU and was sold for 170 USD.
I was stupid enough not to buy it.

Hi QRP,

Yes that the circuit!

I'm only going by this blog: http://www.radiohobbyist.org/blog/?p=271

It stated channel Z "First up, he used a Corsette transmitter, putting out 1.1 watts" - it doesn't say on Dave Martins website what output power it is just QRP!


Dave Martin launched his Corsette transmitter already in June 2009 with the same design but Chris Smolinski wrote about it first in December 2011 in "RadioHobbyist.org".
