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…

The Bubble Nebula is NGC 7635 in Cassiopeia (often discussed in amateur circles because it’s an H II/stellar-wind bubble with associated cool gas). For radio observing, the key idea is that…
Hi Andrew, That’s a question I have been trying to answer for a few years. I will try to summarise what I’ve learned about this below… The OH masers at…
This was purchased for observing water masers at LRO. Water masers are natural microwave amplifiers that occur in dense, warm molecular clouds surrounding young stellar objects or evolved stars. The…
