[bars] Yaesu FT-840 original AM oscillator board

[Andy Wallace]


Juan, I did not know that installation of the AM filter involved removal of that oscillator. 

I have a couple FT-840s which I obtained fairly cheaply because they needed repair. I may fix them and resell. Hopefully to BARS members. :)

Note these rigs have a problematic resistor, R8814, which you can read about on the Web. It causes the rig to die or have PLL lock issues. It’s worth replacing with a higher wattage and relocating to the back panel. 

Now that you have the 6 kHz filter I hope you’ll explore SWL and broadcast listening outside the ham bands. Broadcasting has dwindled but there are still interesting stations to hear.

After upgrading my FT-840 with the extremely hard to find YF-112A/XF-112A AM board, I now have the original board with nothing to do with it. If any of you can put it to good use, you can have it for free. Reply with your address and I will mail it to you. First come, first gone.
