[hpsdr] Very Low Noise VHF Crystal Oscillators

[Chris Bartram]

Hello Tom

Thank you for reminding me of that problem!

The files became corrupted in a backup incident - don't do backups when you 
have local electrical storms! - and I've needed to do some editing of that 
presentation for a very long time. Now that the matter's been raised again, 
I'll try to do something about it!

Many thanks for your kind comments on what you could read!
