hio KF4HAZ
i am impressed at those numbers. I am in the process
of entering the HAM world.
1)Were these transcievers self made. or commercial off
the shelf. Expescially the one u used to tlak to
australia and the northpole
2)could u pls share schematics/designs for these
trascievers
3)would i be right in assuming that u used sky wave
propogation for such large distances?
thanks for your time

The 40 and 80 meter contacts (South-pole by the way) were with an Icom-725 and a
wire dipole about 50ft up horizontally polarized.
80Meter was running E-W which gave more signal N-S.
40 and 80 meter signals were bouncing off the ionosphere.
6 meter was a folded unipole groundplane 100ft. up a tower 739'AMSL using a TNC
and a GE 50MHz transceiver.

VHF 90 mile was on an HTX-202 connected to a 1/4wl groundplane on a 20ft
pole.
The 40 and 80 meter contacts (South-pole by the way) were with an Icom-725
and a wire dipole about 50ft up horizontally polarized.
80Meter was running E-W which gave more signal N-S.
40 and 80 meter signals were bouncing off the ionosphere.
6 meter was a folded unipole groundplane 100ft. up a tower 739'AMSL using a
TNC and a GE 50MHz transceiver.
