I gather from your referenced web page that it seems that a higher damping number was better. Is this a correct assumption ? Well Not exactly, It depends on the type and source of the noise error. The simple answer is that the default damping setting of 1.2 on the Tbolt is a good compromise

Hi, Depending how deep you want, to go you must note that this one from ve2zaz (btw which is a great design given it's simplicity) is a FLL not a PLL. (unlike most of the others that really lock the phase of the signal to the 10KHz or 1pps). Luis Cupido. ct1dmk. Roberto Barrios wrote:

Hi Mark, Thanks for your response, It is good to see that there are some solutions. However ~$1,250 for the Base version of LabView is a bit steep for tinkering in the garage. So it sounds like the NI-Visa and the KE5FX gpib toolkit is all I need to get a graph of the frequencies measured?
