Yeah, is this the last domestic crystal manufacturer left. And do they actually make crystals here? http://bomarcrystal.com/

I don't think anyone uses xtals anymore. Cardinal have made programmable ones for ages and even some of those are going obsolete! $5 for any frequency and with bespoke xtals being $25 for 20+ it's just not worth bothering. Even cheaper are DDS's but then there's the associated circuitry but all that is smaller than an HC6U!
Never mind...

pssst.... there's a crystal oscillator driving that DDS circuit :)

It should be noted that Bomar does not make crystals. They job shop their work to places overseas, which is why one-offs take 6-8 weeks to be made.

Thanks Chris!!!! Well, I still will get DDS OSC's for various projects, but replacement crystals for various older rigs and even TCXO's for a couple of Kenwood rigs that I want to tighten the FREQ spec's on, (Like a TS-50S, a TS-60S, and a TS-711A.). Yes, there are replacement TCXO's out there that some places are offering for stupid money, but why use a middle man, when I can just order what I want from the source?

Same in the UK with 'Quartslab', I was expecting they were made in UK but obviously not as it will probably be CH.
I'm still miffed I didn't 'Discover' Cardinal CPP earlier, even bought a programmer and now they're going obsolete in the half DIL plug in size, most inconvenient!
