Comments:
I was planning SO2R by two filters as
80,40M:TS-930S --> LPF LPF --> Dipole
20,15,10M:IC-756PRO --> HPF --> 3ELE YAGI
but there are some troubles.
Too much 2nd harmonics from 40m to 20m.
Is harmonics generated outside of TX?
A weak filter. The reason of QRP.
Anyway, the contest started.
W and VEs were open together on 20m and 15m Saturday morning.
No Answer on 40m, low band condition was tough to QRP.
so I changed strategy and begun to make DIPLEXER for 20m and 15m/10m.
It completed at the early morning on Sunday
and it was enough for opening on NA.
Operation time was 16 hours, but more spare time was consumed
for DIPLEXER and filters. for design, soldering, adjusting... Hi
Special thanks to the stations who accepted my weak signal.
73, Hisami
