My Radio Shack mono earphone with 1/8" plug does not work unless it's
backed halfway out of the headphone hole. This is not satisfactory
because the slightest movement of the cable disconnects the sound.
I want to purchase a high quality Telex or Byerdynamics mono earphone
but need the ohm rating of the GE Superadio III speaker. Any other
suggestions for radio listening pleasure as one falls off to sleep ?
Could not be happier with the AM sensitivity and excellent sound.
I would prefer a small programmable AM/FM digital radio with equal AM
sensitivity but do not know what to buy.

Your mono earphone does not work in the Superadio III because the headphone
jack (not the output itself) is stereo. This means it is set up to be used
with stereo headphones. When you plug a mono earphone all the way in, it
shorts out one channel of the stereo jack. Since the two channels are
connected directly together inside the radio, this also shorts out the other
channel, ergo, no sound.

The speaker system inside the Superadio III is a nominal 8 to 10 ohms
(though this doesn't matter for headphones, since there is a dropping
resistor in the headphone line which raises the effective impedence to the
headphones).
