RE: [Repeater-Builder] PA question

[Mike Perryman]

Matt,

I 
guess I am not the only one missing part of the intended 
info...
 
1. Jumper around the final.. 
according to Kevin output is now 3W
2. Next put an attenuator 
inline to get the 3W down to 350 mils 
to 500 mils.  9dB should leave approx 325 
mils. There are mini-circuits pads available SMA in SMA out that will handle the 
job with ease.  And they are cheap to 
acquire.
3.  
Don't forget to leave the filter in-line as well.
 
Now you can drive the 110W 
continous duty PA appropriately .
 
This 
is the main reason I don't post to this group.  Most people are too busy 
taking pot-shots at other folks suggestions with little regard for assisting the 
person requesting help.  Conversely, there are some very knowledgable folks 
here who always try to help out.  
 
But the S/N ratio just not up to 
snuff.
 
Kevin W3KKC, thanks for your hospitality 
and the resources you have provided.  Please pardon the bandwidth for my 
rant...  it will be the last one.  I think I can find pretty much 
anything I am looking for posted on your web site.  If not I will pick your 
brain off-line.  There are others who have been most helpful, and focused 
on the issues...  to you all, thanks as well.  I am not going away 
mad...  just going away.
 
To the rest of 
you...
 
See ya down the 
log
 
Mike

  I'm using a Motorla Maxtrac for a 2 
  meter remote base, currently 
  running 40 watts. I have a PA from a 
  Mastr II cont. duty base, that 
  only needs .5 watt for 110 watt 
  output. Anyone know of an easy way to 
  drop the power down on the 
  Maxtrac? These radios wont really go down 
  below 10 watts, and get very flaky under that. I'm 
  thinking about 
  bypassing the final amp stage on the Maxtrac, as 
  the 2nd stage maxes 
  out at about 3 watts to drive the PA to 30 watts. 
  Anyone done this 
  before, or have any other ideas? TIA to all.

  An attenuator to handle 39.5 watts would have to be rather large to 
  handle the heat, I'd just use the coax, less expensive.
