[Elecraft] Q about XV60 pre-installation in K2 #3121

[Don Brown]

Hi

It looks like you have the K160RX manual and the K60XV manual mixed up. C13, C14 and W1 have to do with the K160RX not the K60XV. I assume you are installing the 60 meter/transverter option. In that case you will remove W6 and install J13 and J15. You will change C71 to 120 pf and add the two varactor diodes D19 and D20. Finally you will prepare and install a coax jumper from the RFDET  to one of the pins on J13

  Subject: [Elecraft] Q about XV60 pre-installation in K2 #3121


  I'm at the module pre-installation step of my K2 and am confused by the 
  pre-installation instructions for the XV60.

  It looks like some of the parts have been re-numbered, and I can't 
  figure out what steps of the XV60 manual to perform.

  I have read the D and F K2 manuals and the XV60 manual, and its errata, 
  and searched the mailing list.

  Here are the three questions, in increasing order of my confusion:

  1. Both the Rev D manual for my K2(p.68) and the Rev F manual (p.62) say 
  the same thing:
  [] Do not remove W1.

  There are no occurrences of "W1" in the XV60 Rev A manual.  On p.7 of 
  the XV60 manual under "K2 RF Board Preparation", it says to remove W6.  
  I'm assuming W6 is the correct jumper not to remove. "Yes, we have no 
  bananas." (I.e., this just made me cautious.)

  2. Both the Rev D manual for my K2(p.68) and the Rev F manual (p.62) 
  say:
  [] Complete the steps for J14 through C13 and C14.

  The XV60 manual mentions J14 as part of the transverter installation, 
  but I don't see any specific steps about putting in J14 on the RF board, 
  so it must be RF-J13.  There is an RF-J13 8-pin connector in the XV60 
  that it says to install on the RF board.  So I guess it is really J13 I 
  should install.  That is not too hard.

  3. But I haven't identified C13 and C14 yet so I'm not sure what this 
  means.  The
  only capacitor for on the RF board is RF-C71 and it is a replacement, 
  not an
  installation, and seems an unlikely candidate for pre-installation.  
  Then there are the two varactors RF-D19 and RF-D20.  Which of
  these 3 components should I install/replace now?
  Any ideas or experience?

  Thanks,
  Leigh WA5ZNU.
