[IRCA] XHDATA D-808 Disassembly- Digital and RF Boards

[Gary DeBock <d1028gary@xxxxxxxxxxx>]

For those interested, a detailed internal photo of the D-808's Digital and RF circuit boards is posted at https://dreamcrafts.box.com/s/3bk6dbw08one235bcie8e6elx65360rc

In construction very similar to that of the CC Skywave, the D-808 separates into two main circuit boards, connected together by a plug-in ribbon cable. One strange quirk is that the Si4735 DSP chip is located on the RF board (close to the center right edge). The Si4735 DSP chip is also used in the Eton Traveler III Ultralight radio, and although that model lacks the multiple DSP filter selections of the D-808, is has been the subject of highly successful 7.5" loopstick transplant modifications-- proving that such enhanced Medium Wave and Longwave loopsticks will perform very well in the new, Si4735 chip- powered D-808.

Disassembly of the D-808 model is fairly straightforward in comparison to the CC Skywave models, and the technician doesn't need to memorize a detailed reassembly protocol in order to perform a routine loopstick transplant operation. Neither C.Crane nor XHDATA are likely to show any sympathy to someone botching up an antenna transplant operation, so you need to be convinced that that your skills are superior to those of the company technicians before taking the plunge. In the CC Skywave and CC Skywave SSB models various parts fit together like a puzzle, but the D-808 isn't like that. It should prove to be a fairly popular model for enhanced MW and LW loopsticks.
