Interesting Laurence

I connected with you at 1500 local EST. With the sound card in use I was
unablr to quickly 
shift to the correct audio input and was using my EchoLink mike and
watched as you tuned around the band. I was in Full band mode but looked
like you were using 5/600 hz as the offset and was able to copy WWVH at
60 Khz. That was audio coupled through the mike and had good copy . This
may be a promising method
to allow people to see their signal at DX distance. It was very
interesting to look as you were tuning around

nice quiet location you have
