Amp going backwards

[RodinKy]

Varmit XL250 on low is showing backing up when I modulate, what am I doing wrong?

[Crusher]

Did it start all of a sudden or did you just get? How much drive are you hitting it with?

Yea, that's not a whole lot of information for us to help determine what's up.

What are you judging the modulation swing on?
Do you have a watt meter in line that's showing things?
If so what is your dead key into the amp?
What radio are you driving the amp with?

Watching an inline watt meter, without modulation it is reading 125, with modulation its backing up to about 60. Dead key is 4 watts. Galaxy 2517. This is using the low power setting on the box.

Seems like a lot of deadkey for that little amp. I'm thinking it only needs 1.5-2w dead key.

[RodinKy]

Thanks Crusher, I'll give that a try.

Remember, that's a 250. It's not going to do a lot. Sounds like your using a average meter as well, not a pep meter.
