I the past few days, I noticed that I was getting some mismatch on twenty
meters with my FT-1000D running thru the Henry 3K Premiere but the amp was not
on but by-passed. At first, I thought that I was having a problem with my
TH-11DXX beam but I was getting similar results when feeding to my Bird dummy
load. So I completely by-passed the henry amp and it all seemed to be fine. I
then tried another approach by adding about 10/12 feet of RG-213 coax in the
input line to the Henry amp and the bad swr disappeared on the twenty meter
band but still showing some swr on 18 mhz but more acceptable. All of the
other bands from 160 to 10 meters don't appear to be affected by this syndrome
except slightly on 10 meters. Before I loose too many hairs, has anyone
experienced this weird problem especially with the Henry amp and if so, what
was your cure to rectify this please.
Thanks from Fern VE7GZ
