I have been thinking to make a transverter fed from 2m(or HF) IC706 until I decide on what SDR to build my ultimate all-in-one radio. I think 2.4ghz isn’t so bad for short runs of trace or dead-bug wire as far as watching for accidental capacitance and impedance in the traces. I dont know if I should make the final linear amp a separate thing and put it in a heatsink Al box right at the antenna and just feed it with a bias-T on the 50ohm antenna line. Elegant would be to run everything over one line and multiplex the power and RF with bandpasses. I think I want to make a POTY to add a S band tx antenna to the Ku LNB. As fro RX I guess for now an RTL-SDR<–bias-t<–Bullseye LNB.
Since there is not already a really integrated unit I hate just buying someone else’s project off the shelf and would rather make a few crappy prototypes myself.
How did you make your bias-T for your Ku side? I have been mulling how to wipe out the oscillator noise from whatever boost I use to get the 12v to 14/17v for polarization.
How many dB to say a POTY antenna and a ~1m offset dish is needed to send up a CW or tight digital signal?
Are wifi amps really enough to show up on the transponder? What are those, something like 30dBm or less?
