[Boatanchors] 6146 vs 6146A vs 6146B or 6146W

[Carl]

I agree with Lee and Glen has been preaching this nonsense way too long on 
these forums plus on QRZ.com where W8JI tore your comments up pretty bad.

Glen, its time to edit that web page and stick to basics and as mentioned 
nobody gives a damn about Motorola.

The 6146B's even work in a Heathkit Seneca and a Gonset G-50 just fine as 
well as every HF rig Ive ever tried.
