[MAMS] Back On 222mhz with Amp

[MARK K8MD]

Dave I bought one fan from Fair Radio and I'm not sure if it will work, If you make the pass thru here for June contest(I don't think you rover January contest) I'll show you the fan.

Glad to hear you got it fixed Mark.  I'd love to get a new fan, but I went to 
the Fair Radio site and did not see them listed.  I did buy a new set of bearing 
for the fan from a Canadian fellow on the web, and I will swap those out and see 
if that quiets my 2m amp blower.  


Happy New Year from KF8QL in EN72fu!

I purchased an AM 6155 to fix my AMP. It was not modified so for last couple 
days I exchanged modules and proceeded to do Modes to Different sections and 
exchanged them with what I had. Took 8930 that came with purchased amp and I'm 
seeing 450W most I've seen on band. I'm also operating off of 220VAC which why I 
wrecked the AMP. 


I purchased a Bias module and fan from Fair Radio but they don't look the same. 
I'm thinking that a newer bias circuit was made and manufacture added a small 
board on top of the one I modified. The blower had a board attached to it close 
to the square cage blower. I didn't use them but they maybe good for parts. 73 , 
See in contest Mark, K8MD
