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 for your interest!...."

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=20 old 24 bit digitizers, but I note that 138 stations are effected. We = might well=20 be interested in secondhand sensors if any are being scrapped.
    Do you have any details, please?
 
    Regards,
