[Elecraft] K3EXREF Ext. Frequency Reference Input

[wham727 at aol.com]

No experience with that model but much information is available on line.  I bought the BG7TBL version and a distribution amplifier.  The Lady Heather software said it was accurate over several days to the 12th power...way beyond what I need.  I use the output for my HP frequency  counter and the K3.  Way beyond what we need but fun to play with.  If it doesn’t come with a antenna understand that the antenna has a powered LNA and will need power over the feed line, provided in the model I purchased.  These eBay versions vary due to the fact that they use salvaged parts so depending when it is manufactured it will have a different OCXO for GPS RX installed.  Since accuracy is way beyond what I need (I don’t run a calibration lab).  Fun stuff...Homework assignments is the GPS frequency traceable to the NBS.  :)
