I have two spectrum analysers for sale on behalf of the widow of an old friend of mine.
One is a Marconi TF2370 110 MHz I believe
The other is Tektronics 7603 with 7L18 plug-in 1.5 - 18 GHz.
I do not know if either are working as I do not know enough about them. Therefore I do not know the value.
Both are heavy so really only collect from my QTH south Leicestershire very near jnctn 20 M!.
If any one is seriously interested I may be able to take them to the Harwell Rally 9th Feb.
