Help!

I am trying to open up my FT857 to operate on 5 megs using the Widebander V4 software. The program seems to think that I have succeeded, there are no error messages, but I get “TX ERROR” on the rig when I try to transmit on FE.

Anyone got any suggestions?

Hi Brian

Same thing happened to me.
Not all 857s will wideband with software.
Mine is a USA model and wouldn’t open up with software, so I had to take the other option and go in with the soldering iron.
It’s a bit fiddley and needs good eyes and a steady hand, but simple enough.

ps you need to do the reset after running the software. With the power off, hold in the (F) and (V/M) buttons simultaneously then switch on the radio. (F) is the function button. (DO NOT hold v/m + power)

In reply to G8ADD:
have you done a power reset.(v/m + power)

Thanks, Mike, mine isn’t a USA model, there are no 5 meg channels in the memories, everything is as per UK, but it wouldn’t open. I tried F+V/M+power and all that happened was I lost the beacon frequencies that I had programmed in!

Where do I find details on the hardware mod, please?
