I just noticed that my FT-847 is having a problem with PL tones. There are a few things happening... It seems to want to stay only in a PL of 67.0. When I try to operate on SO-67 that has a PL of 233.6, I can't get into the bird, unless I tailgate. As it seems to default to a PL of 67.0 I can work SO-50 no problem. I checked all my cables, and also went to a different software control program and it all points to a problem with my 847. After some testing with different PL's, using another radio with TQSL set, it seems that when in Satellite mode my 847 will only transmit a PL of 67. I've had my 847 I bought new since 1997 and I never had a problem with This. When I look back I can't remember when I needed any other PL other then 67.0, except 74.4 to open up SO-50, last time about 3 years ago. Before I try a full reset I thought I would ask here, to make sure I'm not missing anything stupid...

Hi
Press the MENU button, rotate the SUB-TUNE knob to select Menu #12, That is "TONE-FRQ". Then rotate the MEM/VFO CH knob to set the right PL. Then press the MENU again to exit.
To activate PL just select FM-mode and press the grey TONE knob (3). There is a sign ENC visible. You can check that the PL is correct by pressing the MENU again. IF not, just rotate the MEM/VFO CH knob.
If that doesn't work out, maybe the memory backup battery has run out of juice. Check also the position of the battery backup switch.
