Position of test points for 54-76MHz Transmit Band pass Filter. On RF board underneath the speaker. FT847 s/n 8Gxxx

It would be best if you check whether I am correct! It is also possible Yaesu may have modified this board. The circuit needs to be traced underneath.

For transmit on 70MHz:-

TP 3011 = MORE THAN 4.5 VOLTS

TP3012 = LESS THAN 0.4 VOLTS

TP3012 = MORE THAN 4.5 VOLTS

I am also interested in the purpose of the add-on board with two relays at the RX input to this board. If I am correct mine is different to those Keith has checked.
