That is interesting: I have several BC-453s and R-23/ARC-5 chopped into 
single channel VLF receivers, all set up for 22.3 KHz. Some even have 
crystal-controlled BFOs. I have several 85 KHz crystals now.

12SG7 for one.

BTW, I aligned the IFs: they were WAAAAAAY off. Gain was substatially 
improved.

I then tried to align the HFO. It now tunes from about 28.25 to 30 MHz.

It is NOT very stable. It sounds as though the HFO coil is hanging loose in 
the box.

I may fix that.
