Hi, I have Yaesu FT-857 for some time but lately I have noticed that my S-meter is not working. Further examination shown that this only happens in FM narrow mode. In FM wide or AM/CW/SSB works ok. If i listen to local hams in FM (wide or normal) I can see S-meter moving, showing accurate readings in my opinion. But when I press NAR button in M menu all the S units get lost. I don't see any reading even when listening to local 2m repeater which is usually 59++. I tried different bands but still the same. I read some info about this problem caused by random change in service menu settings. I checked and mine seems ok. Here you can see example, number in the left column is some reference I found on the internet number in right is my setting. NO-009 FM-S1 68 74 NO-010 FM-FS 99 103 ---- NO-013 FM-TH1 100 101 NO-014 FM-TH2 100 100 NO-015 FM-TI1 10 5 NO-016 FM-TI2 10 7 What I understood from menu is that FM S-meter calibration is done for general FM. There is no extra menu for wide or narrow. Any hints or tips on this issue? I should say that the radio receives signals ok I guess, I dont see any changes in its sensitivity.
