[Milsurplus] WWII Navy RU- Receiver Coils.

[Kenneth G. Gordon]

After my long experiences with my RAL-7, I have never understood why the RU was not 
investigated more thoroughly by hams.

Perhaps it was the usual disparaging comments on it in such publications as the Surplus 
Perversion Manuals, which routinely dissed any TRF or regen receiver, calling the RAL "..a 
hopeless antique, useless for any purpose, not even good for parts..."

Obviously, they had never used any good TRF receiver. I loved my RAL-7, considering it to 
be one of the best receivers I have ever used.

Many of our pilots used the RU with good effect for a long time, and some RUs even were 
still in use at the end of WWII.

Joe Long WA2EJT wrote a pretty good article on the RU for ER Magazine and found it to be 
a stable, sensitive receiver which had several good features.

I remember when Fair Radio Sales was selling complete RU receivers (I don't know the 
models) for very cheap. Most of them were, as I recall it, NIB and had multiple coils with 
them. They are no listed in any of their later catalogs, and I wonder what happened to them. 
Whether they sold them all, or simply put them aside as unsellable.

I wanted one, with the coils, and a good GF transmitter (Joe Long wrote at least two articles 
on the GF for ER Mag, finding it to be an unusually stable transmitter.) for a long time, but 
now I have put that aside.

Anyway, carry on David. I, at least, am very interested in what you discover.
