Re: [K3S] KREF3MDKT

[Raymond METZGER]

Hello,

I recently started assembling the K3S/100 kit (SN 10,614) I bought in 2015, which will include the KPA3A and the KRX3A options (the last one bought mid 2016 when I realized the assembling of the K3s would be simpler if I mount at the same time the Main and the Aux DSP boards). My assembling manual is revision A, dated May 27th, 2015.  I will shortly be installing the KREF3 module (page 52 of the assembling manual). Some days ago, I realized there is a KREF3MDKT kit available at Elecraft, but I'm unable to determine if I need it or not. The modification instructions of the KREF3MDKT kit say :

"The modification is not needed unless
- you have the new KSYN3A synthetisers  and both sub receiver and the K144XV options installed
- or if you have a K3s transceiver.

The KREF3A Reference oscillator in the K3s has been updated as needed at the factory"

 I'm confused by the "Unless...... Or" structure of this sentence.

 
Thank you for clarifying my mind and
I wish to everybody a wonderfull new year 2017

 
Raymond, F4FNT
K2/100, K3/100 and shortly K3s/100 !

The modification is not needed *unless* your adding KSYN3A's to a K3
with a second receiver and a 2m transverter.

If you are building a K3s then you do not need the mod.

Hmm.

"The KREF3A Reference Oscillator in the K3S has been updated as needed
at the factory".

Is this just the resistor mod or has there been a change to the canned TXCO?

Mike,

Concentrate on the "as needed" - not all need the resistor mod.
The TCXO has not changed.
