When Ham Radio guys work a station at a great distance, we call it DX (short for Distance),
like WX is short for Weather. It's a hold-over from the days of CW, / Morse Code.
DX is also frequency based. Low frequency or shortwave (sometimes called HF) is easier for DX,
since the upper atmosphere will bounce space-bound RF signals back down to earth.
So, If I worked NYC from here, on 14.35 MHz, that's not really DX, it's so easy..
But, if I worked NYC on 1.296 GHz, that's real DX!
Because 1.296 GHz is in the micro wave band and will just fly off into deep space.. Like UHF..
Anyways, I'm just NW of Boston and this morning, I yelled "Wow DX" ,
when I saw a plane flying just over the Canadian border..
The plane was at 43,000 feet @ 328km or 182nm..
I never expected to track AC over Canada. I'm amazed.
