Not likely.

You can puchase a pair of good 446MHZ WT, for £10. Prob less on EB. Not worth even thinking about.

Changing the operating frequency from 100 to 400 Mhz involves a lot of mods in the oscillator sections, tunning every stages, including re designing the coils etc. Instead i too agree with the reply given by "m1anh". Cheers
