Yeah, I know this subject has been kicked around for a while, but none
the
less..... When I built the K2, I had no trouble getting the 10W out on 10M.
1) I have rewound T2 and elevated it above the board 1/16 inch.
2) Band Power at W6 Measured output.
20 -33 DBM 2.0 WATTS
10 -29.3 DBM 2.0 WATTS
From the above measurements it seems that at this level the drive at W6
and
the power out of the Low Pass filter at the antenna connection are tracking
fairly well.
3) Band Power at W6 Measured output.
20 -26.3 DBM 10W
10 -26.7 DBM 5W
The drive is still up there, but whoa nellie! What happened to the
output?
This is where 10M flattens out. You can ask for more power, but it just
isn't there. Back in the old days, I would start replacing empty state
devices<G>.
I have checked the components around the 10/12M Low Pass Filter and all
seem correct.
Anybody seen this and got a suggestion.....?
Jim, W4ATK
