[amsat-bb] Funcube 1 (AO-73) vs NAYIF-1 (EO-88) Beacon Power ?

[Iain Young, G7III]

Hi All,

I have been trying to find out what the Beacon Power Output of NAYIF-1
is, but have come up blank with my google searches. Is it just part of
the 500mW transponder ? Or is there a separate dedicated amount as in
AO-73 [Which is 300mW beacon mode, 30mW transponder mode] ?

Essentially, I can decode NAYIF-1 Telemetry. I can also decode AO-73
telemetry when the beacon is in high power (300mW), but not when AO-73
is in Transponder mode, where the beacon is only 30mw (-10dB).

Depending on the power output of NAYIF-1, I may be able to determine
if I really need a 10dB improvement in order to receive AO-73 telemetry
while in transponder mode, or if I am in fact, only need 3 or 6db
improvement, which could change my strategy

(This is a very small station in an urban environment running off a
Raspberry Pi 3, with non steerable antennas, and I'm seeing it as
an engineering experiment)


73s

PS, *grumble* They are too close together frequency wise. Due to
AO-73's frequency issues when coming out of eclipse, I need a wider
(software) BPF. This means NAYIF-1 manages to not only hit it's own
decoder, but AO-73s as well! Great Fun checking if both were visible
at the same time here, and then going, "Has to be NAYIF-1!"
