I want to work QO-100 but I don't know if I want to work it and I'm done, or if I want a permanent QO-100 station. So, I want a plan to build my QO-100 in an Agile fashion, based on my interest and time.

All thoughts / comments / suggestions are welcome as I progress this.

I've revised by build for Phase 1T and ordered the parts. Also working on some DATV parts like a Portsdown 4 so I can receive DATV from QO-100. Next step is to find a decent receive dish locally.

1. Reuse existing kit where possible
2. Make or buy will be decided on time / money
3. Start with the smallest / easiest functioning unit and build up
4. The perfect is the enemy of the good enough - I'm not building the best QO-100 station, just a good enough one

Phase 1R - Initial receive

Phase 1T- Initial transmit

Phase 2R - Improved receive

Phase 2 - Integration of RX and TX into a single station

Phase 3 - Integrate with Portsdown 4 for DATV

Use Goonhilly BATC WebSDR for receive

We will go from Rig → Antenna

• Rig - IC-705 - already own and more than capable of all the modes I want to use
• Patch lead from IC-705 to transceiver - BNC to SMA probably
• Transverter - TBC but options are SG Labs Transverter but I can't find pricing or a UK supplier. Thoughts welcomed!
• Patch lead from transverter to PA or antenna - SMA to SMA (PA) or N-type (antenna)
• PA - might not be needed as 2W out into a 24dBi dish is 300W EIRP…
• Antenna support - Lidl Bike workstand - already owned
• Antenna - Wifi Grid dish antenna Alu 2,4GHz 24 dBi - ordered from Wimo

Decided to replace the Transverter to PA with Easy-100 from RADCOM June 2019 article. This has the following BOM:

• 10dB 10W Attenuator
• 433M Bandpass filter
• 2450MHz Bandpass filter
• 10x SMA-SMA patch leads
• 5V and 8V DC Voltage regulators
• RF Sig Gen (for the LO)
• ADL5350 Mixer module
• Low noise amps
• 8W wifi power amp

Again, we will go from Rig → Antenna

• Rig - PC already owned, using SDR Console
• Rig - SDR Play - RSP-1A SDR - already owned
• Cable from Rig to LNB - Sat cable?
• Bias - T - LNB needs 12V and I think SDR Play only supplies 4.7V / 100mA
• LNB - QO-100 Bullseye TCXO LNB
• Dish - to be sourced - probably local / 2nd hand
• Dish support - TBC

Fully integrated, full duplex solution?

• Rig - IC-9700 or other full duplex radio
• Patch cable / Bias-T (from IC-9700 to Feedpoint)
• Integrated Feedpoint for example POTY or DJ7GP V2 2.4 Ghz & 10 GHz antenna with LNB modified 24 Mhz AMSAT DL
• Dish - reuse from Phase 2R
• Dish Support
