Hi,
I am very slowly putting together a LPRO with a thermal bootstrap
temperature control and clean power supplies (in a separate box).
The LPRO is on a 1/4 inch aluminium plate with fins on the other
side. The LPRO and plate are in a foam plastic insulation jacket.
A small brushless DC fan on the back of the box will suck air over
the fins and it is used to control the temperature of the plate
mounting the LPRO.
It seems to hold temperature to about 1/10 degree. The unit is going
into a steel box to further reduce the ambient magnetic flux.
The frequency trim of the LPRO is a pair of trim pots (coarse and
fine) with a quality voltage reference.
Initially a phase detector and chart recorder will be used with a
TBolt to set the frequency of the LPRO.
However what I would like to do is use a TBolt to discipline the LPRO
so that short and long term accuracy was maximised.
Has anyone set up an LPRO with a TBOLT?
How was it done? Was it successful?
cheers, Neville Michie
