You're right, Tim.  I was using my two FT-817NDs on battery power, 5W
transmit power into my Elk Antennas handheld log periodic.  The antenna
was connected to the radios through a W6ZQ-modified MFJ duplexer, almost
identical to your Diamond duplexer.  Ron - it works great!  Instead of a
straight key, I had a Palm Radio Mini-Paddle on its magnetic base sitting on
top of my transmit radio.

I'm currently northeast of Phoenix, staying in grid DM43iu for the weekend.
There are mountains around here, but they did not bother AO-7 during this
pass.  I worked VO-52 this morning and AO-27 in the afternoon, before it
was time for AO-7.

Yes, still tuning by hand, and trying to conform to the One True Rule in
tuning the higher of the two frequencies whenever possible.  I still want
to get computer control for the radios working via SatPC32, but I did not
want to miss a chance to try AO-7 in mode B tonight.

These were my first two QSOs on AO-7.  I tried AO-7 last summer, using
my dual-band Yagi instead of the log periodic, and could only hear myself
in CW on passes where AO-7 was above 50 degrees or so elevation.  When
AO-7 was around 10-15 degrees elevation tonight, I could hear CW when
my log periodic was leaning against the side of my truck!  And no preamp!!

Thanks to Tim and Dan AJ9K for my first two AO-7 QSOs, and my
apologies for what were probably quick QSOs on my end.  I was hoping
to get them in before the satellite went away from me, and not do too
bad on the CW.  SSB will probably need higher passes for my 5W
portable station, and possibly a preamp, but I can deal with CW.  :-)

73!
