    I got this at a estate sale in the mid 90's and I have not been able to find out anything about it. I have no idea what it does, or what it may be worth. I have never tried to power it, but it is complete. All the tubes are there and the other components look good. Actually the whole thing in general is in rather good shape except for the red screen cover thing. I was wondering if anyone knew what it does and if it is worth keeping. I would be willing to sell or trade it if someone has a use for it. Thanks! 73's - Jeremy KB9MFD

    Thanks for the link, that answers what it does, I thought it would be a scope or some kind of analyzer. I was just searching the model number. But the question remains what is its specs and does it have any historical value. I'm sure just plugging it in and turning it on would be a bad idea, I also have no way to test it if I did. - Jeremy KB9MFD

    The link tells you what IF it works with. I would imagine that any site that is concerned with WW-II radios could use it. The USS Alabama is one, as is the USS Indianapolis. We have a bunch of old RBA's RBB's and RBC's to recreate the ship radio room. The ship is at the bottom of the pacific. No ship site will buy it however, all are donations.

    I would rather give it to someone that could use it rather than keep it, I'll look around and see if I can find some links and sites that may want it, unless you have someone in mind. Thanks!! - Jeremy KB9MFD

    Jeremy -

    This Navy military surplus item is an equivalent of the old Heathkit SB-610 monitor and possibly SB-620 analyzer -- you are more familiar with the spectrum scope feature on the current Icom 756Pro series of radios.
    IF you are looking for hard cash $$ -- then you need to post in the military
    radio collectors swap and for sale sites on the Internet.
    You could also donate it to worthy projects, such as the USS Indy Museum.

    As Bill, W0LPQ has noted these were used on Naval ships.
    The USS Indianapolis (CA-35) a Portland-class cruiser carried the parts for the Atomic bomb
    from the West Coast and across the Pacific to Tinian.
    http://en.wikipedia.org/wiki/USS_Indianapolis_(CA-35)

    Sadly, the USS Indy was torpedoed and sank on its return -- with great loss of life.
    Only 316 sailors survived of its 1,196 member crew.

    http://www.ussindianapolis.org/

    In Indianapolis, they have a Museum to honor this namesake Naval ship (CA-35) and its lost crew.
    The Radio Room (NABD) of that era, before its sinking has been recreated -- original on bottom of Pacific.
    http://www.ussindyradio.org/opnhse.htm

    The museum does accept equipment donations and they have completely restored equipment from that era.
    Educational for the "next generation."

    RBU-2 Panadaptor

    Jeremy
    This is a panadaptor for the WWII RBB receiver that had an IF of 400 Kc
    It has a narrow sweep width 50 vs the usual 100 Kc that you see its brother the RBV which was used with the RBC receivers-the companion HF unit and which resemble the BC 1031s you'll find for the 455 Kc IF receivers in the other services

    I have assembled a major collection of panadaptors and RBA/B/C receivers and would be most interested in giving this unit a "good Home" along with its info posting on a panadaptor web site that I hope to have up in a few months

    I had already donated it to the USS Indianapolis Radio Room Exhibit. Here is the web site: http://www.ussindyradio.org/ussindyradiormexhibit.htm They are planning on getting it working and putting it on one of the radios. Thanks for the offer! - Jeremy - kb9mfd

    Thanks for the update
    This will be a great location for the unit which requires an adapter/cathode follower modification to the RBB - see Chuck McGregor site
    http://home.comcast.net/~cbmcg/Panadaptors.html and BAMA site

    I wouldnt mind one of those donated this way, I have a restored RBB as well as a RBC which I spent several years working on in the Navy in the 60's.
