Strong signal from both here in EM94bw. Dex is wiping out the screen and 
audibly loud enough for a 599 QSO. The loudest that I have ever heard him. I am 
taking turns off my barrel coil to get my antenna matched
As soon as I can. I hope to be on 74 KHz by the weekend. Dex - hopefully we can 
do a QSO
