Oh man this is a good one. It seems that there are some out there fitting these “Stinger” boards inside the actually I think under powered Grant II from President. This board is like the inside of a KL60 amplifier? So am told.
And what does this board do? I’m told you can fit a switch to allow it to work AM/FM and SSB and with 5w input FM it makes 25-35w and in some instances makes 50w SSB. I’ve not seen them personally and if it fits easily as I’m told then why not. But… I’m not convinced it will help. Easier is an external amplifier if you ask me.
The quote I like the best is this
“This amp will make your radio talk the way you have dreamed it would be able to”
Got to ask has anybody tried it? I’m told from USA and Poland people are fitting them into Grants to make “them work like an export radio should”
