K1602TE (note the different part number) oscillators have been sold on
ebay in the past. Keep an eye out there in case more appear. You could
also contact the people who sold them and see if they have one or two
more lurking in the corners.
Other than that, it's just a TCXO that uses the same pinout as all the
others. Match the specs ( or maybe a better one is available today )
and drop it in.

I have an SR620 that I was preparing to sell. It's been clocked by an
external 10 Mhz source for the whole time I've owned it so I wanted to
verify that the internal VCTCXO was still up to snuff. after CALing
the internal reference I set it up to monitor the output from my Tbolt
and it started drifting. the drift was bad enough that I started to
investigate. The internal reference was wandering around by as much as
60 Hz over the course of 10 min. monitoring the EFC voltage at R343
indicated that there was not so much as a mV change during that time.
this has led me to the conclusion that the XO on the board is suspect.
The MtronPTI K1601TE that's on the board is EOL and the replacements
don't seem to be stocked at any of the disti's listed on Mtron's
website that I've checked so far. I've not started the search for ,
Does anyone have any suggestions for replacements?
