From http://www.amsat.org/amsat-new/echo/CTNews.php:

QRP user FM Repeater, V/U (All users restricted to 10 watts or less, omni or handheld antennas) Uplink: 145.880 MHz FM Downlink: 435.150 MHz FM

I think the removal of the "graphic" schedule will force people to spend an extra 10 seconds to read what restrictions or intentions are in effect, and this problem will be solved. I'm sorry it's come to this, again, but we cannot sacrifice civility and order on the air for convenience.

Thankyou, Andrew:

This ongoing "debated" meaning of QRP has devolved a bit. QRP was invented for HF, so its use for VHF+, satellite, and even EME needs a bit of re-definition since the original definition does not satisfy Amsat's purpose or intent (e.g. low power operation).

At VHF and higher frequencies where gain antennas are commonly used the definition is best satisfied if both transmitter output and antenna gain are specified. This leaves less ambiguity to the concept. Exactly what Amsat has done!

Amsat QRP is intended to help the HT + handheld antenna operator. Home stations using high gain antennas with long coax runs need to adjust their transmitter power to compensate for the change in RF radiated power that these afford in order to be in accordance with the spirit of QRP operation.

So follow Andrew's instruction, above for QRP satellite operations. If you need help figuring out how to compensate a large home station's output to comply with QRP, just ask the experts that are present on this list. With some input on your stations makeup, we can calculate what level of power you should operate at.
