[Premium-Rx] Info For CEI Type 356 VLF Receiver

[Gedas]

Hi Terry and TU for that information.  What you said sounds right on the 
money.  No slideback, AM and FM, 5.5 kHz, and USB and LSB modes, BFO 
controls, multi-step 0 dB to 60 dB input attenuator, switchable 50 ohm 
or 1000 ohm antenna input impedance switch on the back, BW's from 1 kHz 
to 50 kHz.....Can't go into too many details here but it is neat that 
30+ years ago I was using this receiver at ARC and now after all that 
time have it back in my possession.  I will grab some detailed pictures 
later today and send them to you directly.  It still has an AEL cal 
sticker on it and on the back I seem to remember seeing a date stamp of 
around 1967.  I was very happy to see when I plugged it in that at least 
all the lights came on and nothing was smoking or smelling.

This is why some people appear bright until you hear them speak.
