[Elecraft] OT: FL-2100Z input SWR

[Arie Kleingeld PA3A]

David,

I had a fl2100z for years and just sold it a few weeks ago to make room
for a K3.

As Don said, the input is fixed but there is another thing that gives
you the higher SWR: feedback form the tuned anode circuit. There is a
neutrodynisation capacitor for that. It is supposed to neutralize the
feedback.
In your case, you'll probably see the SWR going up and down when you
tune the Amp. The capacitor is not properly set then.

The neutralizing capacitor must be set that there is little change in
SWR when you tune. 


For the rest: use the auto tune of the transceiver. Done that for years
and worked fb.

Hi folks,

I have decided to try you guys on this reflector for help as a last DIY 
resort.

I have an FL-2100Z and it has relatively high SWR on 80, 40, and 20 
meter bands of around 1.9 to 2.0.  Does anyone having insight in how to 
adjust this?

Regards,

Dave
