    Phil Erickson, W1PJE, sits on a million watt UHF transmitter at the MIT Haystack Observatory, where he studies the atmosphere and radio propagation. Phil is a long time radio guy but a newcomer to amateur radio. As you will hear in this QSO Today, the tools, modes, and technology of amateur radio are complimenting the research achievements of scientists like Phil, W1PJE.

    Thanks for posting this one! And as far as the coolest antenna contest goes...he wins. (Although at first it looks like the coolest roller coaster in the world!) -dt

    Na verdade não (just a couple words - but enough to respond in kind to PY6FA)

    I've worked with the 43 meter / 140' at Green Bank (2nd largest on site and largest equatorial mount telescope in the world; see below - left hand building is feed access gantry) but not the GBT you've pictured ... yet. That 110 meter offset feed antenna is an amazing feat of engineering, as is the older 43 meter one which rides on a single spherical bearing - and which can point at the ground since it is a right ascension/declination primary axis mount! NRAO certainly has world class antennas.

    Oh wow...the 140 foot....takes me back.... I babied that guy for my VLBI thesis observations in 1980...

    FYI for those who are interested, NRAO Greenbank is now the 'Green Bank Observatory' (GBO).

    I live in Goffstown and when the 1295Mhz radar is turned in my direction, it will pin the needle on my 1.2Ghz gear. Sounds like a purring cat. I'm line of site to Haystack on the south side of Uncanoonuc. There is a pole on the summit of Uncanoonuc that is laying on the ground. It used to be erected to align the radar at Millstone/Haystack and when it was a BMEWS development facility built by Raytheon.

    That's what I thought at first glance!

    Interesting. Can you estimate how long the pole is? My colleagues will be curious - but none are contemporaneous with that initial development work though, as it took place roughly between 1956 - 1961/62. FYI, the development of the radar was not through Raytheon, but all internal to MIT Lincoln Laboratory. Raytheon later built the operational sites, but MIT Lincoln did the R+D and delivered the working plans.

    Great stuff. Do you have a log of the times when the transmitter was and will be on? I would be interesting to see if the RF-Seismograph can pick up the changes. Send the log to my e-mail or post it here for everyone.
    You can see the real time graph here:

    Thank you and good luck!
