| YAESU FTDX3000 100W. This is the main unit in my shack. However, it has a problem where it cannot adjust the power/proc. I can adjust the microphone level on the coaxial cable, but I can't adjust it by turning the outer knob. In SSB and FT8, power can be adjusted at the MIC level, but in CW, full power is output, so a linear amplifier cannot be used.  |
|||||||||||||||||
| A video of my daughter Jolyna explaining the breakdown. |
|||||||||||||||||
| I asked a YAESU distributor in the Philippines for a quote and they said
it would cost $450 plus shipping to and from Manila. I can't ask casually
FTDX3000 control unit (CNTL Unit)  |
|||||||||||||||||
| I previously suspected that the volume unit was broken, so I ordered a replacement from a YAESU distributor in Manila. However, the symptoms did not improve  |
|||||||||||||||||
| So I decided to try and fix it myself. First, find the service manual I searched on GoogleVR7ED has uploaded the service manual.I was doing that. However, even when printed on A4 size paper, the text is too small to read.  |
|||||||||||||||||
| I enlarged the PDF file to the maximum of 500 times and it was finally readable. Control unit (CNTL Unit) CPU R5F61663FPU (Renesas H8SX/1663 series) The signal enclosed in the red frame is sent from the rotary encoder of the volume unit (VR-A-UNIT). Microphone level signals are MICUD and MICCK, and power adjustment signals are PRCUD and PRCCK  |
|||||||||||||||||
| Pulses are visible on the rotary encoders MIA, MIB, PRA, and PRB of the volume unit (VR-A-UNIT). Pulses are also output from the flat cable connectors PRCUD (10PIN), PRCCK (11PIN), MICUD (12PIN), and MICCK (13PIN).  |
|||||||||||||||||
| However, the flat cable on the receiving side of the control unit (CNTL UNIT)... No pulses can be detected on PRCUD (9PIN) and PRCCK (8PIN) with connector J3010VR. To begin with, I didn't know the pin layout of this connector. It took me a day and a half to troubleshoot the problem while consulting ChatGPT. ChatGPT will make various suggestions, such as the buffer that receives the rotary encoder signal or the pull-up resistor going bad.  |
|||||||||||||||||
| I used my reading glasses + magnifying glass to follow the pattern. I then found that the signal from the ribbon cable was directly input to the CPU R5F61663FPU. A tester showed that there was continuity. MICUD receives pulses from the Micro Tarley Encoder But there is no pulse in PRCUD. At this point I suspected the J3010VR connector.  |
|||||||||||||||||
| So I bought some enamel wire and tried to wire directly from the VR-A-UNIT to the CPU. Howeverpackage: 144-pin LQFP (Low Profile Quad Flat Package)Pin Pitch: 0.50 mm.of. It was extremely difficult to solder directly to the CPU pins. I failed many times and sometimes even the main VFO stopped working due to a tiny solder bridge. I almost gave up many times along the way because I ended up bridging the pins with solder.  |
|||||||||||||||||
| After struggling with the solder bridge for about three hours, I finally got it to work properly. Next is the cloudy LCD repair. I have already purchased a polarizing sheet, but I am worried that it will damage the LCD screen.  |
|||||||||||||||||
I use a desk lamp to brighten my work and a magnifying glass to work with.  |
|||||||||||||||||
| The oscilloscope that was extremely useful in this repair was the Tektronix 2445A 150MHz 4ch. But it's heavy and big, and it's a 45-year-old Ohiroscope, so it's very old and it's about to break.
 |
|||||||||||||||||
| You'll want a modern LCD oscilloscope. 8,965 pesos (USD $157.6) on Shopee, a Philippine online store Well, I'll hold off on buying it while the Tektronix 2445A is still working.  |
