Other than a trip which might get the odd mention I will detail projects I am working on, what I want to be working on and what I have otherwise to report on. I will update the individual projects as they advance. As asked I have started to catalogue the references I have follow the link on the left where you can obtain them too. Want to email me wander over to qrz.com and you'll find my email address there. Also twitter @m1kta_qrp

Hi,
Local oscillator to the FST3257 mixer.

10 MHZ TO 1.4 GHZ I2C PROGRAMMABLE XO/VCXO
Apologies... was not asked what is an Si570 that I know as did they but which version is it... looks like the bag standard Si570 (abt £15 in UK).
I have an unmade KX3 in the shack (DXpedition stable mate to my other one) and I will hi-res photo the boards and blog the build.
I still wish Elecraft would release the circuit diagram as the risk of chnese knock off has to have passed by now...
