Re: My FT-847 won't transmit on 80m
Hi Greg, check the Group Files section, there is a folder there - FT847 Mods - in there you will find a Yeasu datasheet on frequency mods, it extends the range of the set. i uploaded it quite a while ago to the original Yahoo Group.

Re: My FT-847 won't transmit on 80m
Out of band mod?? I wasn't aware that there were any such mods for
the radio (e.g. to get it to Tx on the WARC bands)...

Thanks for the replies. I have not yet fully unpacked the truck
from Field Day. When I do bring the radio back into the shack I'll
try a full reset, try transmitting on freqs across the 80m band
and then perhaps try the out of band mod.

Re: My FT-847 won't transmit on 80m
Try wide banding it then a reset, failing that? as these radios are rather old, so perform an alignment, this should sort it out.

Did you perform a memory clear all reset? On Monday, June 27, 2022, 4:04 PM, Dave K?EKL <k0ekl@...> wrote: I have an 847 that I use almost exclusively for VHF/UHF week signal work and for satellites but it got pressed into service for our local club's Field Day this last weekend.
It performed perfectly on 10, 15, 20, and 40 but when trying to transmit on 80 meters the display reads "ERROR". This happens whether the radio is set for CW, SSB, AM or FM and it doesn't seem to matter is PTT is asserted via the DATA IN or PKT connectors, the footswitch connector, or the front panel mic connector. Again, only 80m is effected.?
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.

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?
