I know from reviewing the manual that the radio will display ERROR if one tries to transmit out of band but I was testing on 3.850 MHz.?
Has anyone seen this before and if so what's the resolution?

Hi, That suggests to me that it’s UK model… our ?80mtr band stops at 3.8Mhz...

Re: Using FT-847 as an oscillator for practice
Just to put my two pennies worth in!
? What key will you be using? Iambic, swipe or straight? If you going to use a DL then I like to use a 600hz side tone (menu 6) as it always felt nicer on the ear, just my preference. Find the monitor setting on the FT847 and use that to adjust your output volume (mine is at 25, side tone menu 8). Set the weight to something that resembles clear dashes and not long ones (maybe worth consulting the “fists” on that) but mines at 3.0 (menu 7). Adjust the delay..... that I would say is quite important. Longer the better for practice as you won’t be interested in QSK break in while practicing and I think 300ms is the longest the rig allows. When driving an transistorised amplifier I find the delay at 300ms still too short as I’m not really expecting break in and I’m not exactly fast so find the carrier dropping in and out in between sentences (menu 9 maximum 300ms). Im sure people will say the opposite and use 10ms as it doesn’t drive the PA as hard but at 5w into a DL I would rather not switch so often and I guess it’s driving my VL1000 and hearing the chattering relays..... sends a shiver down my spine..Naturally you have the speed on the front panel so adjust accordingly.
? Also don’t forget to use the monitor button on the front panel above RF/AF or you won’t hear your side tone and process/keyer button next to it or you won’t have control over the speed and automatic dots and dashes. I use an Iambic key (Kent) and the keyer button give me automatically generated dots and dashes..... lazy I know. Won’t make a difference on a straight key.
? ?These are my preferences and only a guide but you can adjust yours to suit.
Good luck and hope to catch you in my log soon.

You are correct in that you can use a dummy load.
Just be sure to connect it to the correct antenna port.

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?

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.
