Hi Chuck
Are you sure the crystals are exactly on 6.3 MHz?
If I was going to do this, I'd place an request for defective TenTec 6.3
MHz crystal filters. There should be some out there. You can harvest the
good crystals, and use the boards for your custom designs. At least that
way you'll know you have matched crystals, except for the bad one in the
bunch.
Regardless, if you go with Bomar, I'd suggest sending along a good crystal
from a TenTec filter so they can match it.

Pete,
I am going to take a filter and yank one of the crystals and measure
the parameters. I'm pretty sure they are 6.300MHz, as the cost of
custom crystals would be too much.
I do measurements of crystal parameters all the time, so no problem.
The project is on hold for 10 days due to two presentations I am doing
locally and in Alb. NM this month. :-)
Thanks for the email and I am scouting the Universe for rigs that are
being offered up for 'parts only'.

PS. Still looking for the schematics and I'm calling TenTec this a.m. to
see what they have to offer that isn't going to cost me an arm and a
leg. I've got $150 invested in the Paragon and P/S and the only problem
is the low power out.
