When i was a young teenager there I was living in Montreal area . There was a Surplus centre called Radio Centre in Chomedy near the Canadair plant. My father Harry Dulmage , former Instructor at No1 Wireless School in St Hubert during WWII , took me there . They had hundreds of No 11 Wireless sets and dynamotors. I bought one for $4.95 and later bought a dynamotor for both the transmit and recieve power. I had the cable for the transmit power unit but had to make the one for the recieve power. Also i had no tubes. I returned and found a US set that had a complete set of tubes which i bought. The first set was made by Canadian Marconi Company, the second was made by PYE of Manchester England which strangely enough was the company my Dad was working for in Montreal at the time. (PYE Electronics Canada and he was the chief Engineer there.) I took the radio home. Dad looked at it and said it would be no good so we put the tubes into my other set. We powered it up and i check voltages using the schematic that was inside the set glued to the case. Dad told me the most common cause of trouble with these old HF transceivers was bad contaqcts in the long swith running throughout the centre of the radio. He said if I cleaned each contact with carbotet and made sure they had enough spring tenion to maintain contact it would likely work. I found out why he was the youngest instructor ever at No 1 wireless that day. after perfoming the operation as he instructed me I repowered it only to be greeted by morse code signals in my ear as I plugged a small whip into the huge two prong antenna socket in front. I used the radio for several years as a SWL device. I even tested the transmitter ona couple of ocassions. One time Dad was doing some oscilator stability tests on a HF unit at work and he asked to borrow the NO 11 for comparison. That night he told me it was a surpisingly stable radio. As good at least than the current crop of HF transceivers (1960s) As I grew older I got interested in cars and left the radio at my last bording place west of montreal. I wonder if it is still there. There is one in the Communications Museum in Kingston as well. Sure wish I had another one! Don Dulmage VE3LYX
