The X-Lock VFO stabiliser works!

My VFO stabiliser is now working and has locked the old TS120S VFO and cured it's until now temperature related frequency drifts. It worked very well at stabilising the VFO initially but because of over compensation the receiver would not decode WSPR signals. However after reducing the varactor to VFO coupling, all is now working very well. I am very pleased with the X-Lock from Cumbria designs.
