[Yaesu] FT920 question --- VK2LEE

[Jim Hargrave]

Hi Lee,

That is the way mine started. I adjusted the oscillator and it started
coming on right away for about a year. Then it finally died.

I replaced the crystal and it has worked great ever since. The original had
weak output. I got my crystal from International Crystals and it worked
right out of the box. I tweaked it up using an RF voltmeter and a counter.
That was almost a year ago. It has been working fine ever since.
