Re: FT847 on digi
开云体育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 Doppler shift split frequencies going up and down. ? Apart from that, very good results with SignaLink SL-1 and homebrew interface. ? However, some issues with SCU-17 data port on FT847 cannot communicate with HF due to no data output in HF via data socket. ? Hope this helps. ? De Spence M0STO?

Re: 60 Meter Transmit Mod Info Wanted
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 On Sat, 25 Mar 2023, 13:22 Andrew Lenton, <a@...> wrote:

Re: 60 Meter Transmit Mod Info Wanted
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 4M RX performance beyond the 6 M performance! TX BPF mod, will give you 85 Watts on TX, you could add a further 70MHZ BPF if you wish, to bring the 2nd harmonic down a bit more. I have done the above mod on two FT 847, and they worked extremely well, I sold them both in a weak moment!

Is there anybody who is willing to do the mod on an 847 as suggested by Leighton GW3FSP. Best regards Sent from Jeff M0UHF On 24 Mar 2023, at 12:30, gw3fsp via groups.io <gw3fsp.ldavies@...> wrote: |

Re: 60 Meter Transmit Mod Info Wanted
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 to allow much higher power out and drastically reduce the current taken when on 4M, both my 847's are fitted with the preamps and filters modified, have not seen the mod mentioned since.

Re: 60 Meter Transmit Mod Info Wanted
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 info, Ihave done this mod to both my 847's with no problems what so ever.

Re: 60 Meter Transmit Mod Info Wanted
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 changes did anything at all except causing me to have to reset all my settings and memories it gives "error" when going out of any band from 160M - 70cm I enabled the AK emergency channel? in the menu and it will TX there but it would have done that any way? anyone ever have success with this? |
