K3 - s/n 1591 - TCXO module question

[Ann and/or Bill Tekatch]

Hello everyone.

Things are going really well with the build of s/n 1591 (I had the power
on tonight for the initial power-up test - so exciting!!!) but tonight
when I went to put the TCXO module on the KREF board, I discovered that
the leads on the module are too long to allow its bottom to "rest
against the socket" as described on p.46 of the assembly manual. Is this
a problem? Do I need to trim the leads?
FYI the leads are 1/4" long and a gap of 1/16" is left between the
bottom of the TCXO module and its socket when it is fully engaged.

BTW for those of you keeping track of delivery times:

K3 kit ordered May 9
Katiegram August 27
Delivery on Sept. 5

I really appreciated receiving this info. when I was awaiting my K3 - my
thanks to everyone who shared this info. on the reflector!

Thanks for looking & 73

Ann T.

You do want the oscillator to sit tight in the socket, but I found
there was a tiny amount of lead exposed due to rubber pads on the
underside of the oscillator can near the leads, prevented a "perfect"
fit. [1]

My opinion (and it is a cheap opinion at that) is that if the gap is
large enough to measure, then it large enough you can trim the leads
by that much. :-)

FWIW, on K3 #1595 (ordered 7 May, Katiegram 27 August, arrived 5 September,
on the air 6 September), I found the leads on the TCXO (standard 5 ppm
version) to be too long as well, so I trimmed a bit (maybe 3/32" or so) off
each one before installing the TCXO. I told myself that if disaster struck
and it didn't work, I would order the 1 ppm TCXO to replace it, but so far
it has been doing just fine here.

73,

Hello,
I had the same problem and solved it without trimming the leads. The module
dont't rest against the socket but sits above it. No trouble till now...
just a week !
Is there a builder alert on this subject ?

Thank you, Luc. I trimmed the leads and the radio is working fine so
far. You've had the same results without trimming the leads, so it would
appear that it isn't critical.
