Quartz Crystals where to Purchase them
It is getting exceedingly difficult to obtain custom cut quartz crystals for ham radio use in small quantities MOST COMPANIES NOW ARE ONLY INTERESTED IN BULK QUANTITIES .This company in the eastern Bloc is very friendly and so cost effective , i have used them as have others here in new Zealand . Prices are very good . They are very helpful , English is not a problem for Josef and the turnaround about 3 weeks is good I have no problem recommending this company .You must pay by bank draft as they do not use visa or paypal but in this day that is hardly an issue .
the bank details are below . My low tolerance HC49/U overtone Ham Radio crystals where under US$10 each !! Drop josepf a line he will answer all you questions . and will give you a quote for what you wish including airmail postage ..

Re: Quotation
Dear Mike,
many thanks for your inquiry. We can quote you the required crystals as
follows:
1) 44.55 MHz / 3.OT - 2 pcs
2) 44.75 MHz / 3.OT - 2 pcs
3) 39.05 MHz / 3.OT - 1 pc
4) 17.65 MHz / 1.OT - 1 pcs (please note that this frequency we do
not
produce on 3.OT)
Parameters: 20pF / ±50 ppm/ ±50 ppm
5) 29.600 MHz / 1.OT - 2 pcs
6) 7.4 MHz / 1.OT - 2 pcs
Parameters: the same as above
Do we understand well, that you need these two frequencies with deviation
from CL = 20 pF?
Also please check and confirm that these crystals should be produced on
1.OT.
We will make the biggest electrode at crystals to achieve the biggest
deviation, but we are not able to let you know just now how big deviation
will be achieved.
