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 FOLLOWING COMES WITH NO WARRANTY OF ANY KIND. TRY THIS AT YOUR OWN RISK – THERE IS A RISK OF DAMAGE TO YOUR EQUIPMENT BY COPYING THE EXPERIENCES DISCUSSED…
For your application, this type of digital attenuator is actually a very useful addition to your radio astronomy test setup. If you are using the NanoVNA as a signal source…

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…
For testing a 22 GHz LNB, you don’t necessarily need a laboratory-grade signal generator. The cheapest options are: If your goal is simply to confirm that your LNB and receiver…
TRIMBLE EXTERNAL CLOCKS: It depends on the specific Trimble device. For Trimble GPS-disciplined oscillators (GPSDOs) commonly used as 10 MHz frequency references: If you mean one of the surplus Trimble…
