[Moon-net] GS23B cavity

[Ingolf Larsson (LN/EAB)]

Hi all.

Does anyone have any information about a Russian commercial (military?)
UHF cavity for the GS23B tetrode. I do not have any name or designation
for the cavity except that it is about 40 cm long and 
painted in a soft yellow colour. The tuning is done by changing the
cavity length by moving a short (both cathode and anode). The tuning
controls are situated at the cathode end of the cavity. The output
coupling 
is also adjustable.

I have not been able to find any reference by searching the internet. I
know this type of cavity has been up for sale at different ham VHF / EME
meetings.

Does anyone know if this cavity is usable / possible to modify for 432
MHz?
