Those were the two xtal sources I was thinking of. I remember only using 2 xtals with my para80set, so 2 may be enough for a novel fun rig.
Been a while since I recalled ceramic vxo, yes if a stash of useful resonators could be found, even a stand alone vxo kit would be interesting. Many apps would do well with 20 some kHz of tuning.
Heard you with a nice skcc signal on 40m today but it was dinnertime.
