Hello again from Helsinki.

Sorry forget to announce my system setup, it is:

Radio: ICOM IC-970 (TX/RX), no separate feedlines only one line which is:
Andrew HJ5-50 type (7/8") about 20 meters from mast to hamshack.
preamplifier: 2 stage with MGF-1302 (1st stage) gain adjusted now to 16 dB
(was earlier more but oscillation occured then, hi), located in hamshack (= at the wrong
end of the cable, hi).
Antennas are 4 pieces F9FT design 21 element yagis.
PA is homebrew 4 pieces MRF-648 (basically 2 pieces 100W semiconductor PA units phased together)
pwr theorically abt. 240W (with 15W input), measured 180W at 10W input pwr (which IC-970 gives),
and with JT65b mode abt. 150-160W (no more).
