Sure enough. The one dated 2010 that I posted looks a whole lot like the monochrome 2006 version.

The one I posted is from a Connex CX4300-300. It has SD1446 transistors in it, so I'm sure there are some value changes, but the schematic looks basically the same.

    Ham radio operators (VHF/UHF) should pay attention to enhanced radio propagation paths throughout the middle latitudes and equatorial region, a common occurrence following such events. :coffee: (y)

    Had "Aurora" propagation on CW/SSB on 6m last evening. (300-700m range here) The 2m guys had lots of Ducting/TROPO between the East Coast and Gulf Coast op's, even early today.
