[Premium-Rx] Cubic Communications R-2145 and R-3030

[Carcia, Frank A. HS]

Hi All,
I'm sorry the 2145 is a R3030A. my unit has 4 filters .5 khz, 1 khz, 3.2 KHz
and 6 khz. It has a serial interface.
Units with serial numbers under 126 or so have the older synthesizer
modules. Biggest problem is key bounce
but John Collins has a good fix by adding a cap in each serial interface. I
was talking about 2451 BFO.
The 3030 usually has 5 filters and IEEE488 interface. All modules not
associated with remote interface have the same part numbers.  fc

Fellow Members:
 
I recently received a inquiry regarding the Cubic R-2145 from John England.
According to the Cubic Communications configuration people, the R-2145 was a
dual R-3030 that bore a part number 2145-1000.  It consisted of two highly
modular, digitally controlled receivers in one heavy 5.25" rack cabinet.  It
did not incorporate DSP.  No information was shared as to how many units
were produced.  It was the last HF receiver manufactured before Cubic
produced the CDR-3150 family, which included DSP.
 
As of this date, Cubic Communication Incorporated (CCI) has been merged with
Cubic Defense and is now called Cubic Defense Applications.
 
Greg
