John. Actually 27mhz is comparatively mild. When you have an FM system where there are multiple uplink attempts (which cannot hear each other trying) and capture effect in play the game is entertaining enough...but then add in the notion of path loss varying almost to individual data bits (not only distance changing, but the various antenna fields involved) and it is an effort really in weak signal work. Power and large antennas are the great equalizer. Robert G. Oler WB5MZO life member AMSAT ARRL NARS

many years ago I would try to get a packet up and down with just my location for the map.
But with so so many trying to work DX I have not done it in about 8 years.
really 27MHz has nothing on this system.
