Hi Herb!!!

   YES!!!!  PLEASE save me a '138!!!!  I'd love to have one in my
collection... Not only that, I have one place I collect that has a SUPER
high background level: I've measured upwards of 50 mR/Hr in spots, but
5-10 mR/Hr is typical. It's HOT, but there are obviously lots of goodies
there in addition to Pitchblende sand. It would be interesting to see how
much of a dose I get collecting...

Best Regards!!!  Tom

Herb!

I sure appreciate your intention of saving a future CD V-138 for me.  If I
ever see more than a picture of a CD V-718 I'll remember you, especially if
there is more than one!!  I've never seen one for auction or for sale
anywhere.

Regards,
Marshall

Hi everyone,
   Sorry about the mistake I made calling the CD V-730 and CD V-740 a
CD V-130 and CD V-140. I will have more CD V-138's comming in (I will
have 6 total). I will check them and save you one Marshall. You too
Tom if you want one. Sorry to hear about the hits your loop took.
I hope that it didn't get inside your radio.
             Later
                Herb

Hi Herb!!!

   Glad you got the 138!!!!! It is a VERY uncommon dosimeter, you've done
well!!!! I've seen 200 R/Hr and 600 R/Hr CDV models, but I've never run
across any of the low range 138 units...
   I'm not familiar with the digital Radiac units: Are they Military? I'm
not surprized to see folks going digital, but I still prefer analog.
   Gotta run... Need to do chores: My 600' loop took a couple of hits this
week, and I need to splice it and get the Johnson 500 back on the air.

Best Regards!!!   Tom

Hi Herb!

When you posted on 99/10/27 you referred to a CDV-142 dosimeter.  Do you
have such a unit, or did you mean 742?  The references to 130 and 140 are
interesting as I have seen the same ranges called 730 and 740.

I wouldn't know how to figure your chances of finding a digital meter.  Any
feeling for my finding another milli-roentgen 138?

Regards,
Marshall

I'm new to the list... saw reference to it while
poking around listings on eBay.... on a lark ended up
buying the following:
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=176979523
(and now following the list to see what I have).
Thanks for all your posts and the links provided to
sites such as http://members.aol.con/allnilo/index.htm

While I don't have much to contribute in the way of
CDV technical know-how, I do have a site that may help
you if you plan to use eBay. I teach computer skills
on the college level and was asked to do a community
presentation on internet auctions a few months back.
Here are the notes:

Hope they're helpful to someone  :-)

Hi everyone,
   There is a CDV-138 dosimeter (which I was told by the seller that it
is the mR version) on Ebay right now. It ends on 4 November 99 at 20:27.
Check it out. Also does anyone know why the CDV-720 makes a high pitch
buzzing sound. I have two (2) of these units and both of them do the same
thing.

Hi everyone,
  I need to know who makes or made (model # also) a geiger counter that will
detect 50mR
and up. Also, I would like to know if switching out the ion chamber in the
CDV715, 17
or 20 with a CDV700 ion chamber would it detect low level radiation. Just an
idea.

Hi Folks!!!

   This website was brought to my attention today: I've checked it out, and
it offers good info on the pitfalls of buying older, tube type &
scintillator geiger counters, as well as practical info on measuring the HV
in counters (for those that don't have access to lab grade type test
equipment!).
   I've listed it as a link on our site for everyone's convenience.

I want to welcome everyone to the CDV-700 Club!!!! If you're into
collecting/tinkering with/modifying/collecting with geiger counters, this is the
place for you!!!!
   I've spent the last several months on Ebay running into many. many wonderful
like minded folks, and I knew something was missing, namely, a place where we
could all come together, and share our interests. Then, I remembered ONELIST,
and here we are!!!
   I am just proficient enough with computers to get myself into difficulties, so
I'm sure this community/email list will get off to a rocky start... Please bear
with me while we work out the bugs, and get the ball rolling...
   Thank you for coming here, and enjoy!!!

Best Regards!!!   Tom Herman
