V252 Setup for AuScope sites

Desired setup:

      Channel 1 IFP#1-LO 8409 - 8425 MHz USB RCP
Channel 2 IFP#1-HI 8425 - 8441 MHz USB RCP
Channel 3 IFP#2-LO 8441 - 8457 MHz USB RCP
Channel 4 IFP#2-HI 8457 - 8473 MHz USB RCP
      Channel 5 IFP#1-LO 8409 - 8425 MHz USB LCP
Channel 6 IFP#1-HI 8425 - 8441 MHz USB LCP
Channel 7 IFP#2-LO 8441 - 8457 MHz USB LCP
Channel 8 IFP#2-HI 8457 - 8473 MHz USB LCP

DBBC Astro or Geo mode will set the first 8 IFs (4 from CoMo A, 4 from CoMo B) the same. Channel mapping is shown at the end of this page.

So for this experiment, CoMo A will be set up for RCP, B for LCP. CoMo A has RCP on input 1, CoMo B and LCP on input 1. (Here's the DBBC back-end wiring schematic for AuScope sites). So DBBC commands should be:

dbbcifa=1,agc,1 dbbcifb=1,agc,1 dbbcform=astro

The remaining DBBCs are not used so go with default

dbbcifc=2,agc,2 dbbcifd=2,agc,2

First LO is 7600 MHz, so frequencies to configure:

CoMo A:

809.00 16 R
825.00 16 R
841.00 16 R
857.00 16 R

CoMo B:

809.00 16 L
825.00 16 L
841.00 16 L
857.00 16 L

Remaining DBBC CoMos are not used so we'll set them all to 300 MHz.
