Usually use 10 watts

I used an Icom IC-208H, so medium power would be 15 watts. I varied it from 5 and 50 watts. Now, I use a Kenwood TM-D700 (primarily for the build-in TNC and display) so medium power is 10 watts. Other power settings are 5 and 50 watts.

Antenna is a 1/4 wave antenna mounted on the trunk lid.

The setup works easily down to ten degrees, and going to 50 watts, is probably good to the horizon. If a low angle pass is desired, would probably run the Arrow antenna mounted on a photo tripod.

Am awaiting the packet mode to be restored to work WA6LIE in Monterey.

A side note. Ham radio was active during the recent earthquake in Kona. See:

The ISS is part of our Hurricane response plan, but am unsure what passes will be in effect during a given hurricane event and whether the crew will be available.

Five watts, nothing more...

Hi!

I've only used 5W for anything I have done with the ISS. My 2m voice contacts and packet usage have all been done with an IC-T7H on a rechargeable battery pack, and the cross-band repeater has been done at the same power level with either an IC-W32A on high power or an IC-2720H at its lowest power. An Arrow Antennas 2m/70cm Yagi really helps, but one of my voice contacts was done with a long telescoping whip on the IC-T7H in December 2005.

73!

I use my IC-T2H handheld (6 watts) for crew voice operations.

When the repeater is on, I use my DJ-S40T (0.5 watts) for the uplink. It works, marginally. :)

73, Zach
