LF: clamping TV-cores

["Dick" <knaap159@zonnet.nl>]

The thing Mal, G3KEV, wrote reminds me in how I had troubles
to 'connect' two TV-U-cores together.
Any suggestions how to stick them together in a good way?
Even the slightest variation in pressure seems to change inductance
in a rather large way.
That's also one of the reasons I am searching for a toroid core.........

It seems to be impossible to find a source for just one or two 3C90 cores
here in Holland or Germany.......
Luckely there might be a solution on its way from the UK?

just to inform you: I'm planning to build a new (1kW) 136kHz station,
including
'portable' antenna system,
that I might take with me to LX later this year..........
