Well, it looks like I got the HW-9 working. Changed the injection levels
for the mixers (2nd mixer still looks suspicious to me) and put in
MRF-476 (I think) finals and turned up a new output transformer
(10 bifilar turns on FT-37-61 core). Now getting 8 watts out on
80 and 40, 4 watts on 20 and 1 watt on 15. (I know, but I can always
turn it down to 5 watts!) First QSO was with DL8UUU on 20m, first call!
So it looks like the HW-9 is go for the Missouri River float.

We will be on the river Saturday 29 May to Friday 4 June. I will try
the following schedules (time is UTC):
        0200 14.055 - 14.060 (that's as close as I am going to get
                                with the HW-9 dial!)
        0230 7.035 - 7.040
        0300 3.555 - 3.560
Hope I can hear some of you guys out there. Should be fun.

I have heard there is a book of mods especially for the HW-9. Can
anybody give me any information?

73, Fred KE7X
