[Premium-Rx] Cubic 3030 info requested.

[John]

Hi Hans,

I'll take a chance and guess you've got something along the lines of a 2411...essentially a military/gov spec'd R3030.  What IF filters does it have?  Just give the readout values-don't break any module inspection stickers yet.  The base R3030 has CPU firmware version 4.7A, non-bouncy keypad (tell me if your keypad is bouncy), 10KHz 1st IF filter, 0,5/1/2/4 KHz 2nd IF mechanical filters, MS-style connector, no speaker output (you can add one), and a 2nd gen keypad with a different keypad layout than the more common R3030A.  If you download the R3030 / 3080 manual on Premium-RX web site, you'll have almost everything you need by way of info.

If I'm not mistaken, list members own 6 different versions of the R3030 series.  They differ in firmware versions, remote control species (GPIB/Serial/Parellel), 1st & 2nd IF filters, rear panel I/O, and test/external processing outputs.  There's also a 1/2 wide single receiver called the R3080.  Very slick - similar idea to the Racal 6830.   The basic receivers are virtually identical.

Does your receiver seem very noisy when idling on an empty channel (antenna connected)?   Do the left and right "S" meters not match?  These problems and more can be fixed rather easily.

in the longer term, I wish you best of luck with the receiver.

John Collins

  Hi John and other repliers to my request.

  Tnx for great response and support.
  As requested there is some further information made available which will clarify/help:

  The memory chips in both CPU modules have a red circular sticker with "R3030 V2-2 9-17-85". There is also a white sticker on the top of the module saying "PROGRAM MEMORY 2143-3110"

  The CPU modules are marked like this:

  Assy No. 2140-1110, S/N 30585-30 
  Assy No. 2140-1110, S/N 30685-30

  The IEEE-488 module is marked like this:

  Assy No. 2140-1112, S/N 05385-30

  The top cover is marked: R-3030 (V). Apparently there has been a military type tag under the left front handle, but this has been removed.

  It does not have a fan, and it has the MS type audio connector (military round multipin).

  Regards and thanks in advance for the reply.

  Hans
