#Yaesu ft847 no power on sideband installThis is where we are going to install the board. This space is earmarked for the installation of the optional CW filter. If like mine your's is a stock radio then you will have a vacant space on the upper left quadrant. On a clean work surface (not like mine) remove both the covers from your FT-847 and place it upside down on the bench with the sockets facing you. Frankly for the amount I5XWW charges for these pre-built boards it's not worth the hassle of building a convertor on a project board. These converters use a freely available design found in a number of places on the Net. A Closeup of the 2 old filter circuit boards with the new coax attached.

Where's my soldering iron?Ī while back I ordered a couple of 455KHz-12KHz down converters from I5XWW with a view to doing this job. I decided to got with the inrad brad filers for the radio 250hz (704c) for the CW portion and 2100hz (702c) for the SSB portion. I've been promising myself that I'd convert my FT-847 to DRM use for a few years but with DRM broadcasts here in the US only being available in the early evening when I'm tied up with family matters there seemed to be little point. There has been some call for the 12KHz mod info since I took my old site down. This post has been reproduced from my old web pages.
