[Elecraft] K3 - KPA3 Duty Cycle Question

[wayne burdick]

Hi Dwight,

We may limit power level or maximum TX time for 100% duty-cycle modes 
(AM/FM/FSK). I can't say for certain, because we're still doing 
extended transmit tests.

We used two fairly large, standard-size fans so they'd run at slow 
speed in most operating situations. But fans in this size are readily 
available with higher CFM ratings, so we could offer an 
extended-duty-cycle upgrade if that were warranted. This would only 
increase the depth of the fans; you wouldn't have to add fans to the 
top of the cabinet.

In fact the entire fan panel is an upgradeable module -- we wanted to 
make sure the K3 could adapt to specialized requirements.

73,
Wayne
