[Elecraft] K2/100 RFI problem using Astron 20A

[Paul Webb]

Hi

I thought I may have had a RFI problem with my K2/100 that I recently =
bought
but it wasn=92t that.

When I hit the tune button sometimes the K2 would start tuning and then =
half
way through do a reset.

In the end I measured   the current into the 100 watt stage and found =
that
as the tuner tried to find a match the current drawn would

Go up and down as you would expect as the load changes.

But I found that my 20 amp PSU could not cope with some of the very =
short
current drain that it was asked for and dropped its voltage which caused =
the
k2 to reset half way through its tune cycle .

I was going to look for a better PSU , till I found how much a new one =
was!

So in the end I have a 17AmHr Gell pack here that I float across the =
PSU=92s
output this will help the PSU cope with the odd high current pulse and =
also
act as a standby Supply in the event of a mains failure.

I guess others have found the same problem?
