This is a database of actual faults and what was required to fix them, based mostly my own experiences, covers many radios, and is being constantly expanded upon, as I repair more radios and come across more faults I add them to the database, members can also add their own tips to the database as well.
This is a listing of radios, with PLL type, PCB number, crystal frequencies, typical modifications, and my own special modification information, which is not available anywhere else !
This is a large listing of radio information, it is really for identifying the PLL used in a radio and whether it can be modified for extra channels, no other information is included, it is meant as a quick guide only.
This is a calculator, which converts between Decimal, Binary and Hex codes, it is a usefull tool for working out PLL N codes.
Click on the image below, it costs only US$25 for 2 years membership
!
The members area has my archive of hundreds of circuit and block diagrams
(well worth the cost even if you can only find one diagram that you want
!).
I also have more radio information, taken from my own records on modifications
that are not listed in the public section of the site, the members section
has new diagrams added every month or so, or whenever I get some new ones
to add.
Members are also mailed from time to time with a list of the latest updates
and additions to the site, and of course, members get priority over the
other visitors to the site.
This counter shows the number of hits since the 28th October 2004
