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 ..
Here is a copy of the quote from the company http://www.krystaly.cz/en/ .. for the units I required
This is just to give you an Idea of the transaction
