I went through the sequence a few times this morning, still couldn't get the VHF ranging to work.
As for how I'm configuring, starting on the CSM flight plan at T 100+00 there's an Undocking Checklist, after undocking I'm setting up the EMS and VHF per this checklist. Later, on the LM Timeline Checklist at T 100+46 during the Rendezvous Radar Checkout I'm placing the LM VHF A XMTR to VOICE/RNG. And then when directed I'm back in the CSM, and going to RESET with the VHF RNG switch. My EMS shows 00 (two zeros, no decimal point displayed).
(FWIW I do show a good lock, tracking in the LGC position, N78 and tapemeters agree)
In the Apollo 15 Flight Journal, during this test they had the CSM "go to Simplex A". I think that's because they had lost comm prior to that, but I played around with the VHF AM switch, going from OFF (where the CSM Flight Plan Undock Checklist has it) to Simplex A, and it had no effect on the VHF range on the EMS. I then tried different comm switch positions, VHF antenna positions, playing around with different configurations to see if I could get some reading on the EMS, no joy.
A couple of additional questions/comments: A while back when I ran the CSM RR Activation I couldn't find the "decal" so I used the procedure in the AOH 4.5.6.9. The last step shows in test position B a reading for "RRT AGC SIG", if that's referring to the VHF ranging system (?) I'm showing a reading of about 0.9 when locked on. And when I first started the test my LM HTR CONT TEMP gauge showed a RNDZ radar temp of about zero. After running it for a while the temp comes up, but on panel 11 the HEATERS/RNDZ RDR/STBY circuit breaker is out per the LM Activation Checklist Undocking CB Chart, and I can't find anywhere where I was supposed to push it in (if it's supposed to be in?)
I don't want to beat this to death, but if I'm messing this up I'd like to get it right. Thanks.
