Mode Zero

Shaun - This is absolutely fabulous! Thank you so much for taking the time to find, scan and upload . Very helpful info that would have taken ages to fathom out otherwise. Seems my assumption was correct. The missing TX components and the selectable tab link means this has been assembled as a carrier wave Tx so all that is actually missing is the valve which I think I can get from eBay

Hi Guys
For those of you taking interest here ( particularly Mike K ) I also have an Ivy Tx and Rx also both Carrier (CW) only
Here are some photos showing the differences
Ivy proceeds and is on the left

Tx bottom Rx top in all cases

First signs of life! Needle deflections at 1’ range

So questions arising, what is the field strength of the transmitter and is de super regererative detector quenching?
