Thanks for the response Rob. Nice web page you have too -> What's in Milky Way ... Besides Us? I had been thinking that the OP project could be a great teaching aid in secondary school STEM. 73, John, WØPV
The site of the 'horn' is now called the "Green Bank Observatory". It is no longer part of the 'National Radio Astronomy Observatory'. FYI---
To increase the integration time, a tracker is required. You can build one or buy one for this small antenna.
that's easy: a good equitorial mount, as I noted above, will allow integration times up to almost 12hours at a time..... and can be reset with good accuracy for multi-day integrations.
Yes, you are correct. I've been there on/off since the mid-80s. Old habit of calling it NRAO. Just love using the 20 m telescope for extra-galactic flux measurements.
My web page has been used at both the high school and college level. I built it while working on the 3.5 cm & 2.1 cm galactic plane survey using the 13.6 m dual-frequency radio telescope.
WoW This project is totally amazing ... I always wanted to do some of this .. Very good job, regards.
