In the March 1987 (Vol 6, Number 3) issue of Monitoring Times on page 48, there is a short article on how to modify your RadioShack Scanner to pick up the cellular frequencies. (This just had to have been leaked from someone in Tandy sales!) 1. Remove the four cabinet screws and the cabinet 2. Turn the receiver upside down and locate circuit board PC-3 3. Remove seven screws holding board and plug CN-501 4. Carefully lift up the board and locate diode soldered in place below the module {In the large article, it mentions "a matrix of diodes attached to the microprocessor's input port, which is often used to configure radios for sale in different markets. From recent flux on the circuit board, it appears that a diode had been added/removed", this is the diode in question.} 5. Snip one lead of the diode carefully, leaving it suspended by the other lead for later reattachment if desired, such as warranty repair 6. Reverse first four steps above for reassembly. Radio will now cover 825-845 and 870-890 MHz and search in 30 KHz increments for no-gap 760-1300 MHz reception (Thanks to Jim Marquand and other readers of Monitoring Times) I do not own a PRO-2004, nor have I ever seen this tried, do it at your own risk. `on
