 G'day  all,

I use a  HP 6269B  supply to kick the dyno along on ART-13,  and the
like with a 28 V battery to handle the starting current.
Witha 0-40V and 0to 50 amp  adjustable rating, it all works fine until
the RF  from the TX invades the  space and  the PS either oscillates
or shuts down.
It's one of these constant voltage /constant current boxes with a
series regulator and a triac preregulator. I think their main use  was
for  battery charging.
Our 240V 3 wire input line is  grounded appropriately.
Maybe someone can suggest where  bypasses/ferites etc can be placed...
I 've got a manual/schematic. Alternatively a signal to HP /Agilent
may turn up suggested  cures, but thought someone with connexions over
there may have been this way before.
