Recommendations from Eduard Mol: I don’t know what software you use to control the mount, but W49 is listed in Stellarium which apparently has an integration with the giant astronomical…
For your 6.6685 GHz methanol-line receiver, the best Mini-Circuits connectorised choice is probably: Mini-Circuits ZX60-14LN-S+ Other suitable choices include: Model Frequency range Typical gain Typical noise figure Assessment ZX60-14LN-S+ 0.05–10…
Water masers are produced when water vapour (H₂O) molecules in space act as a natural microwave laser. The word maser stands for Microwave Amplification by Stimulated Emission of Radiation. Here’s…
W49 is a radio source rather than a single visible object. It consists of two main components: Most planetarium programs don’t label “W49” by default, but you can usually locate…
Yes, your spreadsheet is set up in the right way provided that the 1.72 dB is a power Y-factor. where (Y) must be a power ratio, not an amplitude (voltage)…
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…
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…
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…
