The answer is still no. To get a level output you need a totally different circuit that has
uniform gain from lowest frequency to the highest. The BS170 device can do that
but the circuit its in is not designed with that in mind.
The easy way is to live with what the BS170 does at 10M for your amp, then use a relay
or manual switch to insert an attenuator for the 80M (or several switches) to make
it right levels for any lower band. This is by far the easiest way.
