This FT-757 GX has issue of right receive frequency. It is receiving stations around 600Hz below over different bands. I tried to follow the alignment procedure as per Service Manuel. My experience shared here. Tnx es 73 de VU2KPU Prakash
Great video and explaination. Thank you. I have FT-757GX and it JUMPS frequency about 500 cycles back and forth and looks to be off frequency on 10 meters. Thank you for this great video.
A bad contact due the oxidisation is a typical problem not only in FT-757GX, but in many old models. Some of them works well after only a few triming moves, some need a chemical cleaning with "Contaclean" or other similar spray, depending a capacitor type. Few years ago I replaced a 3 trimming capacitors in a FT-767GX because they were uncleanable.
FT-757GX have a digitally controlled PLL, working from one reference oscillator. This model have no internal calibrator. Only an older radios with mechanical VFOs have them. And need check and trimming with the same method.
