I have an early FT-847 sitting on 40.680 FT8 right now. I've also used it on 2M with no problems. 432 is a bit of a problem as my Ft-847 is off by about 1.7khz on 432. This is far enough away from

Oh Yes I love that interface. Ian’s nice design is Similar to mine which was a 600:600 transformer and 1k:8 ohm much like the pdf. I think I also used a 2N2222 and used it to drive a 2N33

Hi Please find attached the Sound Card interface circuit diagram which I have used for the past 20 years. Works all mode all bands, and was originally designed by the guys who wrote W95SSTV and

What Spence said, I would add that the 847 was built back when doing "data" communication on HF involved different "TNC" equipment than VHF, so (I presume) they designed it to segregate the various

Yes and WSPR and JT65HF. Also recently used on GreenCube but a lot of hassle due to GreenCube being simplex and the FT847 having to work doppler shifting and split on the same band. Very tricky to

Has anyone used the 847 on FT4/8 or other digi modes on 2M and 432?? Hal/WB4AEG

The 48 Mhz is way before the PA. I forget the exact figure, but it was not many dB down from the 70 Mhz signal

The pre amp mod that replaces the 4 m borad is no longer available, I have the Gerber files and a few boards made. All the parts are surface mount, there is one mc109 coil for tuning. This mod brings

The 60 metre mod is easily done by simply widebanding the radio. 60 metres is not in the processor, as 60 metres was not thought of when the radio was new. Ref 4 metres, I looked in to doing the mods,

HI, how are you getting on with the information for your mod information requested? It seems to have stopped are you having it done? Are you going to do it yourself? Is there anybody who is willing to

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? ?reset
