More Maser musings...

[Steve Olney]

Hi All,

I've been spending some time looking in detail at the maserdb database (thanks Eduard!) with the idea of seeing whether a 'blue-sky' project for long-term monitoring of a group of masers would be fun.  I think I've figured out a way of monitoring 52 water masers with a 1 m dish without tracking required and within the 2.4 MHz bandwidth afforded by a RTL-SDR dongle. 

It's a bit convoluted - so best written up in a PDF.  If the initial analysis survives a more detailed analysis I will post it here - but it IS a'blue-sky' project - so that may not happen...;-)

Cheers

If you can accurately drive in elevation-only, this seems doable.   Let the earth spin objects into view.  That's how we're currently
  running our big dish (12.8m) for RRLs.

Hi Marcus,

Don't hold your breath :-) It's all just a notion in my head from looking at the maserdb database. I need to do some analysis to see if there is any major gotchas...

I have been in that state more times than I care to admit..... :)

If you have thousands of antennas, you can do that in the HF band too.

Anyone know if the UTR-2 is still functioning?
