[Hammarlund] Ronald McDonald's SP-600

[thoyer1 at verizon.net]

I have a CR-91A with a Northern Electric label on the front and an sP-600
with a Northern Electric ID plate on it. Yup, two different entities......

Well... I'm sorry but...
Northern RADIO (New York) have nothing to do with Northern ELECTRIC (Toronto
+ Montreal).
Northern Electric was the manufacturing arm of Bell Canada (counterpart of
Western Electric).
>From the ID tag of the modified SP-600s, they were modified by Northern
RADIO in New York.

I believe Northern Electric modified stock SP600's under govt contract (Cold
War) for the Navy? The mod was specifically for diversity RTTY reception. 

I've had the model in the photo for a decade or more...it is a gem and
pleasure to use. Of course I'm using it as a straightforward general purpose
receiver (500 kHz thru 56 mHz). No product detector but it copies sideband
fine using RF gain and volume controls. 

I am thinning out my boatanchor collection, and this receiver is available
for those who wish to add it to theirs.

version of the SP-600 was very similar. AFAIK these were painted in standard
SP-600 colors.  It's possible fairly large lots of receivers might have been
finished in custom colors for some customers.Sent from my GalaxyRichard
