Guys,
Someone on the fora pointed out that we all have different 49 MHz oscillators! I guess that many K3 owners *have bought oscillators delivered without input for the voltage control* not knowing that a future locking to an external reference would *not* be possible. The KTCXO3-1 delivered to me is manufactured by *KS* Electronics (part number 1099) and pin 1 (VCTRL) is *not connected* internally. *It can´t even be used to be locked in a PLL*. Also if a PLL is to be implemented you need to specify *Kv (tuning sensitivity)* for all oscillators to be delivered to your customers in order to keep the PLL loop filter working correctly. Did you offer a solution to this when you envisioned a *“REF IN (SMA): input for future external reference”.* * * Which type of oscillator delivered by Elecraft have VCTRL connected to pin #1 ?** What is the Kv specified pin #1 is connected? Comment on this please! 73 Jan ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
