[Elecraft] KPA-500 high gain modification?

[Oliver Dröse]

Hi Geoff,

sure, could be an alternative. The appeal of NOT needing it would be less 
clutter, i.e. not an additional box that needs to be transported, wired, 
subject to failure, etc. Just imagine going to an expedition with just a KX3 
and KPA500 for a very small but effective powerful station ... couldn't be 
easier than that. ;-)) That was what I was thinking about ...

For the K3 there probably is the "money factor" for quite some people, too, 
as it would save the cost for the internal 100 W PA (no problem here, needed 
it for my tube amp anyway as it requires 50-60 W drive). Needing a "driver 
amp" (i.e. from 5/10 to 35/40 W) will add significant cost again for those 
not into homebrewing (and to a lesser extend to those homebrewing, too). 
Just taking the KPA3 is then probably the better solution again as it also 
adds better system integration compared to an additional "driver amp" 
between a K3/10 and the KPA500. But I can well understand the K3/10 users' 
desires, too. ;-))
