The Japanese FP-301D manual is correct.
It's just a bear to markup the sheet with a pencil and then create the ordered 2 byte list for a PROM Programmer.

Re: FT-301D steady on "tx"
Hi Othmar and welcome to the group!? Whether or not to repair the 301D is up to you but if you do repair it you will have a fine rig.? The display problem is common with the LED units burning out.?

FT-301D steady on "tx"
Hi from Vienna !
I joined the group because I got an FT-301D from a silent-key (sk abt 8 years ago).

Re: FP-301D ID PROM
First test almost perfect.
Telsa 188 clone and TI 288 work fine.

Re: Rubber plug on right side
Hi Randy,
thank you for your answer, I also made the same hypothesis but there is
no need of an accessible point for maintenance with the cover
closed.
Just rotate the jack 90 degrees and you save

Re: Rubber plug on right side
Pino,
Benvenuto.
The 3.5mm jack is an undocumented feature to break and connect to the RF CARD directly. Why, I no idea but the schematic shows it. Patso. Perhaps a way to use only the RF CARD and PA

Re: Need 10A and 10B crystals - my 301D came from a good buddy.
I'll check my junker 301 later today.
The first FT-301D I restored? is fully operational in good buddy land (41.5MHz crystal)

Re: FT-301D Restoration Complete
This was my biggest 301 challenge to date.
Glad it's behind me, what a pain, too many rabbit holes!
The unmodified drift is 300-400Hz I'm told, like other rigs from its day.
My KWM2-A drifts that much
