For the flight from UK to USA to SARA Eastern Conference to process data at altitude vs data on ground for my talk at the conference. https://www.astronomy.me.uk/wp-content/uploads/2026/07/John-Savage-PicoMuon-Explorer-JS_PicoMuon3_2026-07-23.zip
Andy – I compared several inexpensive GPS disciplined Reference Oscillators in 2023: https://www.reeve.com/Documents/Articles%20Papers/Reeve_GDOComp.pdf or https://www.astronomy.me.uk/wp-content/uploads/2026/07/Reeve_GDOComp.pdf Whitham Reeve
Yes. The Norsat 9000LDF requires DC power supplied up the coax, so if your SDR or receiver does not provide this, you will need a bias tee (bias-T). For the…
For a Norsat 9000LDF LNB, you want a well-regulated, low-noise 12 V DC power supply. Switching power supplies can inject RF noise into sensitive radio astronomy equipment, so quality matters.…
Since yesterday, I have been running a Smallrig cooler plonked on top of my UKRAA PicoMuon detector. I am impressed. Whole casing is kept cool, runs very quietly, whole device…
For the Norsat 9000LDF: The relationship is: IF = RF − 20.250 GHz So in SDR# you tune to the IF frequency. Some examples: RF frequency SDR# tune to 21.200…
I mean Norsat 9000LDF where input is 21.200-22.200 GHz and local oscillator (LO) is 20.250 GHz. For the Norsat 9000LDF: The relationship is: IF = RF − 20.250 GHz So…
Would this successfully act as replacement for TERRASAT Microwave 6.4 – 7.1 GHz RX RF Mixer SMA ED-0280-1 MDC6471-035 ? https://www.ebay.co.uk/itm/205984985415?mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5339129536&toolid=20006&customid=958c8a6bc681104a2b53e0377cfda14b&loc_physical_ms=42038&loc_interest_ms=&msclkid=958c8a6bc681104a2b53e0377cfda14b To be a suitable replacement it needs to have:RF…
I am exploring the possibility of building a receiver to observe the 6.668519 GHz Class II methanol maser line using amateur radio astronomy equipment. The 6.7 GHz methanol line is…
