Light Weight Cuban Portable Satellite Station.
Hello,
I want to share with the group a picture of my ultra light weight Portable Satellite Station. This minimum configuration was being tested on yesterday SO-50 pass (Feb. 14, 01:20 UTC) on my roof. Sometimes I use better antennas (an arrow or a 70cm yagi, 2m 5/8 vertical) while operating portable, but when transporting a yagi or an arrow antenna is difficult I use this low efficient but yet capable light weight system that fits on my backpack.

From left to right:
1. Channelized Kenwood TK-270(G) for 2m Uplink with a homebrew telescopic whip. 2. Hearphone with mic for improve the listening of weak and noisy signals, taken from my computer and modified to fitting both TX radio and RX connections. 3. Ultra Light Weight Antenna for 70cm, not too efficient on low elevation but it works great on higher than 20 degrees passes. 4. 12 Volt lead-acid battery, taken from my UPS when it stop to hold the enough amount of current, but it is still long enough for receiving during many hours. 5. My beloved treasure. AOR AR-3000A+ Communication Scanner, All Modes from 0.1 MHz to 2036 MHz. A fellow ham enthusiastic of vacuum tubes radios decided this receiver was too much complex for him, and I didn't wait a minute to buy it from him.

To match the Raydel's idea of the Cuban's Satellite setup...
I have write an article in my blog with some pictures of my satellite setup...
http://co7wt.blogspot.com/2013/02/my-satellite-setup.html
In short (more description and pictures on the blog)
Radios: - 70 cm channelized Kenwood TK860 - 2m Alinco DR-130T with subtone module...
Antennas: - 2m Jpole at 12 meters from the ground with 30m of Heliax LDF-4 50 Ohms cable - 2m DK6ZB kind 28 ohms Yagui with 3 elements (~9 dBi) homebrewed in an Arrow style with the 70cm yagui in building process... - 70cm 6 element DK7ZD kind yagui for 70cm (~17dBi)
I use a PC headset with phones and mic, the mic is for the 2m Alinco and the phones for the kenwood...
