The Walkie-Talkie is not one patent but a combination of patents he put together. My mother has News articles she is bringing on Saturday that show he developed these initial radios in 1930 for the Bush pilots of Cominco (a large Canadian mining company), long before Gross claims. His patents used for the DEW line technology (Doppler Radar) consisted of more than six separate patents such as the Discharge Wave Generator and a separate patent for the Pulse Reception System.

One interesting story, a solar storm after the war eliminated all communication between Alaska and the rest of the United States, panic of sneak attack set in within the U.S. Military. Don had the giant communications antenna at Cominco in Trail B.C. at his disposal and had them tip it on its side so as to utilize the low ionosphere reflection. This allowed the U.S. Military open communication with Alaska for the three day solar storm with Cominco as the go between.

Another interesting story is that Don was told of D-day before it happened and had become important enough in the war effort that the Canadian Defence Department dressed him as a Colonel when he accompanied the Minister of Defence to England just before D-day as they didn't want the Germans knowing he was there, of course Don was never part of the Military but because of this event the Canadian Signal Corps recognize Don as an honorary member (this membership is limited to military service personal) Don received this honour a few years ago when the signal corps confirmed his (honorary) Colonel status during the war. Don was involved in many other technologies during the War.
