[Milsurplus] Mackay/Federal 128AY vlf rx

[wf2u at ws19ops.com]

Marty,

The receiver had at least a couple of versions (one is cabinet the  
other is rack mount if I'm not mistaken): 128AY, 128AX.
I have a couple of 128AY's (or is it AX? - they're the ones in desktop  
cabinets,  I have to look at it when I get home...), one is working OK  
the other one is hissing but deaf but no fireworks/smell, so probably  
no biggie.
These receivers were part of the Federal Radio/Mackay setup on  
Victory/Liberty ships - one of the vendors for the Maritime Commission  
contracts in WW2, the other was RMCA. The 128A(*) were used into at  
least the late 50's with post-WW2 Mackay  equipped Merchant Marine  
ships.
I'm not sure whether the 128AY was also a US Navy "regulation"  
receiver, I have to look into my sources and maybe someone will chime  
in with info.
As to receiving SAQ with it, I  tried a few years ago with the Mackay  
but nothing. In fact I received nothing even with much better VLF  
receivers... Last year I tried with the RAK and then with the 1960's  
vintage Siemens E310 ("Rainbow") marine reciver which is an excellent  
performer but still nothing.

I'll make you a copy of my manual, I may have already scanned and  
saved it. I'll have to look in my manual archives on my server at home.
