Re: Elecraft Digest, Vol 140, Issue 39

Like John, T6EE, I use a TGE Solutions booster unit.  (In my case the marine model
stores.tgelectronics.org/n8xjk-marine-booster <http://stores.tgelectronics.org/n8xjk-marine-booster>  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.

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 or Morse?  If the voltage fluctuates
under a rapidly varying load, this could lead to distortion in the K3 output regardless of the
DC load values.

Hi...

Have you got any contact info (web-page product link?) for "TE Systems"
as you quote below...

The two companies I find searching for "TE Systems" (and variants) one
is in Germany, and has nothing to do with such things.  The other is in
California (USA) but don't list that sort of device in their product line.

Also, what sort of SMPS generated QRM issues (if any) did/do you
experience with that voltage booster?

Regards.

Dave G0WBX.

I think the reference may have been intended to be: TG Electronics.
