An HF amp won't amplify 146 MHz.

Wasn't sure if you had converted it to operate on other bands. And not being
a ham I don't even know the wattage limitations on I think you said 2
meters.

The pills are only good to 30 or 50 MHz depending on the part number.
The broadband transformers limit it even more so. I should take a
picture of the inside of this busted HTX-212 and this 2 meter amp
so you can see the difference in RF circuitry inside them.
