[Elecraft] KPA500 Combiner

[John Harper]

I think the economical use of a combiner might be on DXpeditions where a
number of other KPA500's might already be in attendance (with different
owners).

 

A combiner would allow them to produce a kw on 80/160 (where +3db are most
likely to matter) with equipment they already have.

Those who already have a KPA500 it might be tempted to buy another KPA500

(kit) to get 1 KW output.  This would be a 3 db extra signal strength at a

cost of approx. $4.20 per watt which would be very expensive.  The cost of

the combiner would also have to be considered.  The combiner with a dummy

load and imbalance trip circuit might be feasible to market at approx. $500.

..Well I guess this is too expensive, but it surely would be nice to have a
