I really wish people would try the search function near the top of the pages in this forum when they have a question.
Makes people seem somewhat lazy or uninformed.

That being said, make sure the VA62 is functioning as it should before bothering with the EPROM change. The EPROM will not make it work better. I have found problems that my VA62, like the 3.58MHz and 30Hz Servo outputs are blown (the board and parts are actually burnt).
I have had to fix certain other functions also.
I tried the EPROM and I discovered a possible problem with the frequency accuracy and stability. I noticed in videos made by others that when they use another instrument to measure the IF frequency that it looks unstable also. There may be a problem with the PLL circuit in the VA62 when trying to get it to output a frequency outside its normal range. When I get the necessary equipment I plan to investigate the problem.
