What I need is a relay that will short out the 72k section of the
loading coil receive, so the contacts have to stand many thousands of
volts!
Try a HVK1/2 relais, Specifications say 8kV (dc) switching voltage.
I used it at work upto 15kV (at 8kHz) when it was swiched 'cold' (remove
signal -> switch relay -> put signal back on). I think that is the way you
intend to use it.
This relays (in various configurations) can be found in the Farnell catalog
under order codes :
910-855 for SPNO - 5V with push on terminals
910-867 for SPNO - 12V with push on terminals
910-879 for SPNO - 24V with push on terminals
910-880 for SPNC - 5V with push on terminals
910-909 for SPNC - 24V with push on terminals
910-910 for SPNO - 5V with flying leads
910-922 for SPNO - 12V with flying leads
910-934 for SPNO - 24V with flying leads
910-946 for SPNC - 5V with flying leads
910-960 for SPNC - 12V with flying leads
They cost arround 50 Euro.
