Mystery Object
These are a complete mystery to me at the moment. Do you know what they are? Do you know where information on them can be found? I would be interested to hear from you if you know anything about these curious boxes.
The only name is Mason Engr Conn USA. The boxes are marked S-1, A-2, LFB-1 and T340. The T340 is marked 75-340MHz. I have a second similar unit but in place of the T340 it has a box marked TLF2 and the frequency range is marked as 9-43KHz.
Any info? Please email me hs0zed (then the @ symbol) qsl dot net
