Thanks! That website explained it very well, and seeing the formulas really helped.

Free space path loss is dependent on frequency. All things being equal (distance, antenna gain on both ends, etc), a 2 meter signal has about a 9 dB advantage over a 70cm signal.
Here's an explanation:

Can you explain the 6dB advantage 2m has over 70cm? I've seen it here on
the
amsat-bb, and in the mesh realm when comparing 2.4GHz and 5.8GHz WiFi
gear,
but it still hasn't "clicked."

Nick,
It should be even stronger than AO-27's 500 mW, AO-27 had a 70cm downlink, the EO-80 downlink is on 2 meters, so EO-80's signal should be up to 9 dB stronger than AO-27 (12 dB stronger if they run it at 1 watt).

Thats very good news, Hopefully the two get activated before field
day?
Im most looking forward to EO-80, It should be like AO-27 with 500Mw or
1W.
Good to know both are working well and wish a long life to them.
