[Elecraft] TGE voltage booster dynamics with K3

[Oliver Johns]

I had a nonsense subject line on my previous submission of this.  So, 
resubmitting it in case someone has some ideas.


Like John, T6EE, I use a TGE Solutions booster unit.  (In my case the marine 
model
>  with a 35Ah AGM 
battery.)
It is set for 14 volts and, according to the K3 voltage metering, holds that 
voltage 
with battery voltage as low as 11 Volts, which is low as I like to go.

My question is, has anyone with an oscilloscope done any tests of the DYNAMIC 
behaviour of 
this or similar units under the rapidly varying load presented by SSB?  If the 
voltage fluctuates
under a rapidly varying load, this could lead to distortion in the K3 output 
regardless of the 
DC load values.

73,

...as well as that of any other transceiver...
