Gentlemen

A week ago I released Ver 7.20 where I  mistakenly took into account polarity
dispersion twice.  The Sun Y factor was thus 3dB less that it should have been. 
Earlier versions were correct, only 7.20 was in error.

The latest and corrected Version 7.21 is now available from www.vk3um.com
and it has an increased display resolution of Point Source Jy for those with
such needs.

Sorry about that  guys.

Dont forget Cambridge if you can possibly make it .. it will surely be a 'good un'
and they have promised ice cold 807's and 3B28's.
