I have noticed recently that when I am tuning into an LOC/ILS frequency for guidance, every time I push the PTT button, my lateral needle disappears. Once I am done with the transmission and let off the PTT button, the needle comes back. The vertical needle is unaffected nor if I am guided by GPS or VOR.
No changes in wiring or other setup has been done and it was working fine just till the last time I was on an ILS approach. I am suspecting my VOR antenna which is in the wing tip may have been shifted or touching a metal part was wondering if anything else could cause this. This setup is with a 430W & GRT Horizon.
Any thought ????
Thanks in advance
