[R-390] R390A mechanical filter repair - new web site

[Graham Baxter]

Hi All

Al Tirevold  WA0HQQ has kindly undertaken to host the filter repair
article on the excellent r-390a.net web site

Its new home is:

http://r-390a.net/FilterRepair/index.html

Hopefully this will be much easier to find than its old location in a
backwater of delphelectronics.co.uk

Thank you Al !
