Hi Chris -


I sent an email to ASL, to check on the availability of
seismometers.  Following is their reply.


"...The digital upgrades don't include replacement of seismometers,
unfortunately for the PSN.  However, it's possible that we will do
some seismometer replacements in the future.  We'll contact you
if  and when some old seismometers become available.  Thanks

Considering the pace of government, this could easily be years, so it
does not look like anything is available at this time or in the
foreseeable future.  I will keep an eye open for this and if it
transpires, I will let the PSN group know. As I said earlier, the last
time this was done was about 10 years ago and involved the KS-36000 a
cold war borescope receiver that weighed about 200 lbs without the
case.  If you do a google search on the KS-36000, you will see a few
old PSN emails about the instrument.


Cheers,


Bob

Hi Bob,

 

    I don't think that we would be very interested in old
24 bit digitizers, but I note that 138 stations are effected. We might
well be interested in secondhand sensors if any are being scrapped. 

    Do you have any details, please?

 

    Regards,
