Re: FM sender with DDAR

[jonny.g.farmer@xxxxxxx]

Thanks for the comments Keith. I'm just a bit worried that the range
is covering too many houses - more chance of someone being upset as I

broadcasts.

I've also been following the curtain debate with interest -they re
still way too expensive!!

Cheers

Jonathan
