On of the major shortcomings of the Yaesu FT301D was the display. The original 7 segment displays also contained the counter circuitry. It was an usual approach, but with those displays commonly available back then failed displays could be (relatively) easily changed out. Since they became scarce (and subsequently expensive) I suspect a few otherwise functional FT301Ds have sold off or relegated to the shelf. Roland, HB9GAA, has designed a replacement display kit - the EL-31 - that duplicates the functionality of the display-logic unit PB1542 in a drop in board. This is a kit - but the board is a thru hole design - so building it doesn't tax dexterity or eye sight. I spend a total of 4 hours putting it together, another 15 minutes testing and calibrating it, and approximately 1 hour changing out the old board with the new, buttoning up the radio, etc. The board and components are excellent quality and the instructions are complete. Instructions are downloaded from the company website and run 23 pages. A large section of that is on setup of the display since it has quite a bit more functionality than the board it's replacing. One of the interesting features is that the display can be set to 'auto' mode which provides 10 hz resolution 160-40m and 100 hz resolution on the higher bands, or it can be set to 100 hz resolution on all bands. It also gives a visual power supply voltage readout and display brightness can be varied. All these functions are accessible via a Phillips remote control. Roland will include the remote, less battery, for an additional USD $2. This added the finishing touch to my restoration of the Yaesu 'boatanchor' which is now a joy to operate.
