I was once told by my LHS that when I am sitting around at home setting up my Tx (JR Graupner MC24) i must screw the aerial in or the HF module could overheat and damage itself -- is this true

Cheers Nigel

very likely to be true. You can screw up the
RF output section by not having the antenna
to radiate the power to.

if there is a function on that transmitter to
turn it on w/o powering up the RF section, then
do that.

You should have the antenna attached to your radio when it is powered up. The transmitter is designed to transmit power out of the antenna, when you don't have the antenna your are removing a critical part of the system. It won't immediately overheat and burn up with the antenna removed, but why put undue stress on the components. Screwing the antenna on is easy enough

Do you not have the option to direct connect as my JR's do ? And therefore you can fully remove the RF module.

And the problem comes from with no antenna/load you get all the power
reflected back into the final amp. NOT GOOD.
