From a quick google search, the b4 seems to be the same as the c4.
I could be wrong. There is one opperator I know with a c4 and it sounds real good on the air however I am not sure how stable it is for drift on ssb
Hey I like your idea, I love wild conversions.
If you ever end up modding the top cover and making a 8 tranny 2950 please post
I see where they are doing around 400 watts on SSB @ a price of $625 - $685........
For that price I will just stick with my 2970n2.
I've had the 6900's in the past and will never have another one!
I have done some reading on this radio and am interested if anyone has bought one yet. I realize a radio with an external amp is best but there are times when that set up isn't feasible.
I ended up getting an S9-175 and was really pleased. In fact I just bought a used S9-350 to replace the S9-175. Buying used one can save a lot of money.
