Re: Using FT-847 as an oscillator for practice
Yes you can use your rig.
You are correct in that you can use a dummy load.
Just be sure to connect it to the correct antenna port.
Be sure to turn the power all the way down.

Try this one.
Again, gook luck and have fun

Hi Douglas,
I am not sure I understand
about using a timer chip.
Is this something that needs
to be added to the radio?
I get the impression that the
FT-847 cannot be used for practice.
What if I directed the signal
into a dummy load?

[Reason: Forgot the question] Hello,
I will be learning Morse code and would like to use the FT-847 for practice as an oscillator before going live some day.
How do I use the radio as an oscillator without going over the air?
Thanks,

Re: Strange black band, but not a defective display
Verified better and I confirm, no LCD illness but a black gasket!
It is probably caused by the seal surround of the display moving due to heat.

I have one for sale in clean and perfect working order minus one issue, the subtune rotary encoder has a spot where it sometimes will drop a few counts.
This appears to be a common issue with them as they age (these radios are over 20 years old now), replacing the encoder fixes that.
It will come in the original box with all documents, hand mic and power cord.
Message me direct with an offer and we can discuss.

There is a serial number where the fix was placed into production.?
Prior to that, one could command the rig but not get data back
(similar to the 736R).? I don't recall the exact details, but I
don't believe it is a fix one can apply later, though there's a
Reddit article that suggests otherwise. Not a simple fix,
apparently.

Re: FT-847 CAT Control Problem
the CAT on one of mine works bidirectional with every software I have tried using whatever nullmodem cable and either? a USB to Serial thingy or a hardware port
remember, unless you changed it in the radio the baud rate is 57,600
my other 847 has a issue with either the multiplexer chip or the line from the CPU is dead
I have spent time with that, but its pretty deep surgery
I should revisit that
