I have added a new domain to my web server host, this is more inline with the function of this website. Thew new address is: http://www.homebrewradio.uk however all the old links from http://vhfdx.org.uk should still work and will be redirected.
Here is my collection of Crystal Filters, all narrow band for SSB use ranging from 2.3KHZ – 2.9KHz bandwidth with 455KHz, 500Khz, 1.4MHz, 9MHz and 10.7MHz center frequencies – safe to say I am covered for future projects until I can figure out a DSP IF solution – watch this space…
