[Milsurplus] 12BY7 with tiny crystals?

[David Stinson]

Have any of you tired to use the little,
short and oval "half size" HC-49S crystals
in their DX-100 or other similar rig?
These are the tiny things you see in those inexpensive "QRP" kits on
Amazon.

I ask because I'm working 20 minutes here,
an hour there to get a Bendix 430 fishing
boat radio running. "Stock" uses HC-6 xtals.

The little "shorties" won't give enough drive
to run the Bendix circuit:

No buffer or multiplier here. Note the crystal
is between the plate and signal grid and has
310V B+ on it.

Here is the DX-100 transmitter circuit, minus the crystal switch
and clamper. The crystal is between the signal grid
and the screen grid- a variation of the Electron Coupled?

I'm wondering if the 12BY7 in the DX-100 configuration
would perform better with the "shortie" crystals than
the Bendix circuit. What do you think?
