Replied to the thread Minimum Dish size for QO-100 receive from S2 location (23N 90E ).PostHi, it looks correct. The SPF5189 can reach this output power at maximum. Consider a few dBm less. The reason for not using a SPF5189 at output is that it has the same gain but cannot produce the required power. Maybe you need to lower the output of SDR,… -

I have run a similar setup in the beginning. I see that you use 2 SPF5189. May be you overload the second. You must make a dB budget for your setup. IE : HackRF (how many dB it sends), BPF (loss dB?), calculate dBm, SPF5189(how mush gain),calculate… -

Can you please check if this should work (I am confuse, in this site it said minimum PEP is… -

Replied to the thread Minimum Dish size for QO-100 receive from S2 location (23N 90E ).PostHello all,
Here is the plan for my setup. I am concern about the following two issue:
1. The 15m run of coaxial in the TX chain. Can you advise if this would work? It is difficult for me to put much equipment at the antenna site (i.e. remote SDR using a… -
