The power switch on my FT-847 is starting to have issues and while I am in the process of locating where to have it replaced, is it advisable to use the power supply to turn the rig on and off? Thanks

Hi Hal, this is a circuit I use for all sorts of data modes, this one I made for my Clansman kit. The circuit is always the same just the wiring details change, it's cheap and easy to make. Leighton.

Thanks for all the replies. Helps lots. 73/Hal. WB4AEG

Hi Spence Thanks for your reply. It's funny you should mention using an optocoupler. The one I originally built for my FT-100 back then and still use for my FT-817 uses a 4N25 optocoupler for PTT

The ext Speaker option is used if you find using the low level Line Input on your sound card doesn't have enough to drive the software (mainly SSTV from what I remember) as opposed to using the

Nice interface, Ian. Curious, why use the external speaker jack, given that its output is dependent on the front panel volume control and subject to being mis-set? There is a fixed level

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

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
