Hi Mike,
look for any kind of radio-receiver, which would receive around 5MHz the
old 60 meter broadcast ban, connect to power any kind of wire which
could serve as antenna turn it on and try to find WWW at 5MHz, after
that power up your 5MHz oscillator connect piece of wire to the 5 MHz
outpu
Bob,
In this case, I know how it was taken off the board - it wasn't. They just cut
the board around it. I had to remove it myself. Nice thing about that, is that
I got a nice plastic, pre-formed part that fits between the board and the
OCXO, probably as an insulator.
You are also right about the
I want to thank everyone who provided helpful comments regarding the
sick HP3561A, both on and off the list. Special thanks also to a
list member who made PDFs of V1 and V2 of the service manual
available. As it turns out, the only fault I have found so far was
fixed before we received the sc
Hi
Best guess is these things get taken off the board with either a big torch or a
charcoal fire.
You can ask Mr Google to dig up pictures of the process. Depending on just how
quick
they are, the insides of the OCXO can easily be reflowed. The likelihood of it

The vendor is resending it. He has not said what he wants done with the dead
one. Probably nothing, in which case I will tear it apart. Probably won't fix
anything, but at least I'll get a good look inside. And the SC crystal could
always be used in a custom DOCXO.

Hi
What I have found on all of these is that the harder you look, the more you
toss out. I get a lot more from some batches than others to this or that point
in the testing. In some groups > 80% of them do not have working ovens or

There are no hard specs on these surplus uni
