xv tansverters

[Joseph McIntire]

Hello all,
   I have two Elecraft transverters One I put together in about 2009 it is a 144Mhz. after building and going through the alignment procedures I could not get it to work properly. I got side tracked and set it aside and have not messed with it since. A month or so ago I pulled out the other one which is a 50Mhz transverter. Both of these were purchased by my father in law. He started the build on the 50 Mhz unit then at some point his key fell silent. So when we clean out the house I packed all we could find of it in a box. And a month or so ago I went to finish it. And was surprised to find I was only short by one resistor. But in trying to get all my Elecraft manuals in one place I found an Errata for Xv transverters dated may, 11 2011 Rev. D-3. The main change there is L19 The older Errata states to delete the step to remove the tuning slug in L19. And the later one Rev. D-3 states page 17, Parts Inventory, XV144: Add the following new part at the bottom of the page.  L19
  1 each 198 nH, 7MM, RF Inductor, Violet E690226. My question is this for both 144 and 50 Mhz transverters or just the 144 Mhz units. The reason I ask is neither one has the tuning slug in that location nor does it appear there ever was one. And the manuals are for the 50, 144, and the 222 Mhz units with just a few differences. At the end there is a small section that has you in stall the proper parts for the specific unit you are assembling.

Joe,

Errata that was issued after the ship date of your units is not
applicable to your unit.
This particular errata applies only to the XV144 and it was necessary
because the crystal manufacturer supplied a crystal that was slightly
off frequency from the prior one.  L19 compensated for that difference.
So if your XV144 is on frequency, do not change it.

OTOH, if that errata was shipped with your XV144, then it is applicable.
I once knew the markings on the old and new crystals, but have
forgotten.  You might want to search far back in the archives for
relevant information from Gary Surrency.
