Interferometers need hardware bias tees for SAWBird H+ 1420MHz filters with cascaded amplifiers, (which they also need as AD8302 chip requires certain level power input on SMA connectors to work) as

I am John

I am not, but owning an RSPDuo I would also be interested to hear if this is possible or of anyone using one for RA applications. Adrian

Afternoon Is anyone here running Spectrum Lab with an RSPDuo ? Kind Regards John B

Hi All I've received some e fantastic advice on making and testing AD8302 based interferometer and have summarised it on my website and thought I'd share the link here for anyone else interested in

Following responses received, I propose to run this Saturday 10 February @ 1930-2100. Let me know whether this suits or is a problem? Andy

Hi Andrew. Those results look good. To understand the final test (different frequencies in the two arms of the phase detector) it is better to think of a phase detector as an RF mixer. The device will

I think I'm a step towards sorting this out - new AD8302 phase comparator board. Taken much of stuck off old layout and starting as simply as possible. Found I had stabilised 5V power supply in shack

I would be very interested Kind regards -- ched ched@...
