    Respectfully:  All major multiseat American aircraft during WWII that flew over the oceans were required to have transmit and receive capability on at least 500 kilohertz and maintain the watches twice an hour just like any other "ship."   I have original radio operator log sheets confirming this with notations for the "quiet time" watches.
I've dug back through my reference material over the weekend. I still stand by my "Tertiary Powers" hypothesis. During the 1930s, the radios available for aircraft would have been like onto the SCR -130 series.  These sets were primarily purposed for air to air and air to ground communication and based on the 1926 Naval Radio accords.  They cover the frequencies of which we are discussing, topping out at 2 megahertz. The small air forces of third world powers with their extremely limited budgets, lacking the resources to develop a native avionics industry, would follow the lead of the "First World."  They would not be quick nor have the budget to change to the latest technology, just as is the case today.  Single seat American aircraft equipped with the "latest and greatest" HF and VHF Command Sets could not liaison in the air with the small air forces of say, Nicaragua. If a patrol of Nicaraguan biplanes spotted a submarine off their coast, they'd need to be able to talk to the Allied strike aircraft on their SCR 134 sets. One can't wait for such hot tactical information to grind through the comm mills of two countries.  I'm betting coffee and donuts that incidents just like this led to the "special purposes" procurements.  I think, and with I believe good reasons, that these "special purposes" where exactly this.
Side note: I used the example of Iran in my last post about this.  Iran was invaded and conquered by Britain and Russia during the war.  Their small air force was destroyed at that time.
