    International Crystal closing in May

    Their announcement is all over the various newsgroups but it's worth mentioning and discussing here.

    ICM had an extensive database of older amateur and commercial equipment, and the types of crystals (HET, BFO, fixed-channel, etc.) used by each. They would also do limited (single-quantity) runs of a given frequency.

    Are there any other companies which will make crystals to order? If not, this is going to have a HUGE impact in the vintage gear and boat-anchor section of our community. I have a number of projects queued which require one or two custom crystals and I'm sure I'm not the only one.

    Time for all SDR, all the time.

    I guess. Buy the company Fred!

    I can't seem to find the crystal on this DDS board... :P

    If I wanted phase noise and the requisite DSP follow-on stages to clean it out of the passband, there's a number of candidate rigs which could replace my analog stuff.

    One thing I've been considering - if a DDS chip with sufficiently minimal spurious products across its spectrum can be sourced - is the redesign of the HET oscillator section of a few rigs I have kicking around the shack. Rather than using discrete crystals for each band range, a DDS w/ control lines that utilizes existing band switch wiring could be used. Peaking/filter circuits could be implemented for each band, similar to that which is used for the purpose in the crystal oscillator designs. A rig such as the SB-104 will lend itself readily to this approach as the entire HFO assembly is located on one board. Others...might be more challenging.

    But I can certainly find the DDS board's IMD products on my spectrum analyzer ... ;)

    You gotta be kidding. All the frequencies would be off by a few KHz and the pins would fit no known holder. Misfits, you know…
    All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.

    Maybe Dishtronix will pick 'em up.

    So, you're saying you have no faith in Freds abilities?
