Hi there, that info was released by Yeasu quite a few years ago, there is no update now, somewhere there is a 4M pre-amp available for the 847 along with details of how to modify the bandpass filters

Leighton, yes that was the cause of the issue all of the documentation is so very old and conflicting but I can confirm that it works well on 60M the 40M bandpass filter covers from 5 to 7.5Mhz as the

Unfortunately it does not include coverage of the 5Mhz band as far as I can see. Leighton. GW3FSP.

Hi there, there is a list of frequencies covered after the mod included in the info, as always a full reset is required after changing any of the links to make sure the processor picks up the new band

Morning Leighton yes thats where the info comes from but it is clear as mud from the chart what the consequences of the changes are the big missing bit is full reset? (FAST+LOCK and power on)

Hi there, there is a mod sheet in the Files section from Yeasu - Band modifications for 847 frequencies - which gives the link information to broad band the 847. leighton. GW3FSP.

never mind, all is well turns out that none of the instructions I have found included the 3 finger salute reset? (hold FAST and LOCK while powering up) all I found was the MENU #39 all init?

update but I just did the changes to one of my 847s started with one like this and finished with it looking like this I used 0 ohm resistors instead of a? solder bridge and i cant find that the

Thanks, I was aware of that. The current experimental band is 40.660 to 40.700 for US stations. At this stage I don't even have a license to transmit on 8 meter. Tom

Hi Tom, just a work of warning!! There is an fundamental at 36mhz. Be very weary about transmitting anywhere near that frequency. De Spence M0STO Sent while portable! please excuse

I've tried receiving 8M signals with my FT-847. So far I decoded two stations on 40.680 Mhz using the 847 and an 80M wire. 73, Tom K6EU k6eu@...

Has anyone tried using an 847 on the new experimental 8M band? I've been monitoring 40.680 (FT8) for several days without success. Given the time of year, this is no surprise but, I wonder, how

If anyone is parting out an 847, looking for the front plastic panel. Mine got cracked in shipping. Thank you! Kent K9EZ

All, So what I found out is the ALC modification that I implemented to use the 847 with transverter's disabled the SAT mode function. I'm not sure why but removing the diode that was suggest by

Could it be the Same band? Inhibit the loop back effect? De Spence M0STO Sent while portable! please excuse typos.

Hello, I have an 847 that won't transmit while in SAT Mode. The radio works fine in all modes, bands and powers at half-duplex and in split mode but when in SAT Mode, the radio won't transmit.

Hi, I'm just picking up on this thread but I've had a similar problem before.... the two screw terminals that clamp down the incoming cable inside the FT847 are prone to working loose. Also inline

I would respectfully suggest that people are jumping to conclusions without logical thinking. Perhaps if the original poster bothered to read answers, it may help. I have asked what size PSU he is

Yes, I agree, the power on switches are known as a fault on many radios and would cause this problem. Not that I’ve ever had one fail on me like that. But if there was a problem with that, you would
