BASIC Tech Group - MyNews 12 - All my hardware shieldprojects update

I need a list of where I am with all my projects. So here it is

CONCEPT - 2015

1. DDS & RTC shield. Si5351 DDS, outputs G0 (CLK0), G1 (CLK1) & 74AC74 for I/Q outputs. Eagle SCH & BRD files OK, PCBs made

2. SDR RX shield. FST3251 QSD & TLV6424 Amp. 40m input filter. I/Q inputs from DDS & RTC shield. Eagle SCH & BRD files OK, PCBs made.

BASIC - 2016/7

3. VFO-Simple shield. A 40m Varicap tuned VFO for Intermediate students to build. Eagle SCH & BRD OK, PCBs in production.

4. DCRX shield. NE602/SA612 mixer & LM386 Amp. 40m input filter, input from DDS & RTC. Eagle SCG & BRD OK, PCBs made.

5. DCRX_WIDE shield. NE602/SA612 mixer & LM386 Amp. Wide band 50R input matching. Use external BPF for each band. Eagle SCH & BRD OK. PCBs not made, as PCB above can be used.

6. QRP_RIG_BASIC shield. Complete Rig RX & TX. FST3251 QSD & QSE, SSM2135 for audio ccts. Wide band input, use BPF for band selection. Eagle SCH & BRD OK. PCB in production.

7. RF_METER shield. Input 40dB attenuator, AD8307. Output 20MHz LPF ERA-2SM buffer. Eagle SCH & BRD OK, PCB made

8. RETURN_LOSS shield. Antenna analyser bridge, circuit under development. Proto done, software shaky

9. WSPR_PA. No design done, may use commercial 2W wide band amp driven by DDS & RTC via BPF, need LPF on output? Could use for QRP_RIG if arrange TX/RX switching...

10. BPF_BASIC shield. Design done for 40, 30 & 20m BPF, 2KHZ BW Chev. Eagle SCH &BRD OK. PCB in production. Tested, doesn't work abandoned Replaced by 3xLPF shield

Future

External PA 20-50W to be defined, stand alone with internal PSU & LPFs, maybe Antenna auto tuning?
