[MRCG] Net Propagation

[JAMES FALLS]

I use it when choosing between my dipoles and vertical on the roof. Thing I find interesting is how the MUF builds back up in the early morning, then bounces up and down like a basketball in our daylight hours. Then it drops into 160-Land so fast an hour or so after dusk. 

Personally, I think it’s Aliens from that Secret UFO Base north of me vacuuming up stray electrons before they fall off the terminator into the Pacific. 😜

Eventually, I’ll build another “tuna” and have each antenna pre-tuned so I can switch between them when propagation craters.
