|The GE SuperRadio III is now shipping.
|
|The SRIII is essentially the same physical box as the SRII reworked
|so as to be aesthetically pleasing to those who thought the SRII was
|ugly. Everything looks rounded off. The only change to the layout
|is an additional switch for AM wide/normal selectivity. The innards
|are probably very much the same as in the SRII.
|
|I wish they had included a momentary-on dial light switch, but ....
|
|I haven't bought a unit. What follows is all from the
|GE spec-sheets. It remains to be seen whether there will still
|be a demand for after-market filter modifications.
|
|As with the SRII, the SRIII is available from Bennet Bros for
|only $36.88 + S&H. They expect to be caught up on the back-orders
|by mid-September. The Chicago number is 1-800-621-2626. NJ is 800-
|631-3838.
|
|Below are some excerpts gleaned from the spec-sheet for
|  General Electric Model 7-2887:  (new features = **)
|
|+++++++++++
|
|GE SUPERRADIO III High Performance AM/FM Radio
|
|"Designed for maximum reception and sound performance"
|
|For Exceptional Sound Quality
|
|      6 1/2" high sensitivity woofer
|      2" cone tweeter
|      700mw RMS audio output
|      Separate rotary bass and treble controls to personalize sound
|**?   Built-in loudness control in volume control to automatically
|             boost bass response at low volume levels (so you don't
|             have to fiddle with the bass control every time you
|             change the volume)
|
|For Superior AM/FM Reception (long-range performance)
|
|**?   Varactor tuning diodes with tuned RF on FM and AM
|      38" swivel whip antenna
|      7 7/8" ferrite rod antenna
|      External AM/FM antenna terminals
|**    Expanded frequency range on AM (over SRII)    <--- NOTE THIS
|
|For Best Selectivity
|
|      4 IF tuned circuits on AM
|**    "AM Accent" switchable AM bandwidth for maximum selectivity
|             of adjacent stations (normal) or improved audio response
|             of strong signal stations (wide)
|**    Logging Scale across top of dial (was in-between AM and FM scales
|             on SRII)
|      Precision vernier tuning (looks like the tuning knob has a dimple
|             in it for spinning with a fingertip)
|      Ceramic IF filter plus 3 IF tuned circuits on FM
|      AFC (Automatic Frequency Control) reduces drift on FM
|      AFC defeat switch for fine tuning of adjacent stations
|
|Plus Other Features
|
|      6 "D" cell operation for up to 460 hours battery life (4 hrs/day)
|      Automatic switching from AC house current to batteries
|      Separate power ON/OFF switch (still on top right of set)
|      Headphone jack for optional headphones (model 3-5750)
|      Uses (still uses) GE AM/FM intergrated circuit
|      Fold down carry handle
|      Expanded steel speaker grill
|      12.5"W x 10.5"H x 4.5"D
|      6.4 lbs shipping weight
|      One-year limited warranty
|
|From the picture
|
|**    Rounded aerodynamic case design "Attractive new styling with
|             look of performance."
|**    Plastic covering over dial scale is now flush with the rest of case
|      Three switches (horizontally: AM bandwidth(**); AM/FM; AFC on/off)
|             and three knobs (vertically: Treble; Bass; Volume)
|             located in the space to the right of speakers
|      Tuning knob on right with a dimple(**) for spinning
|      Headphone jack below tuning knob
|
|Anyone tryed one of these out yet?

There appears to be some difference in these two descriptions. The one
says the extended AM band coverage is lacking, while the other says the
AM band coverage has been expanded.
                 ^^^

I would think that any current-design radio tuning the AM BCB would go
up to 1700 kHz. Does the FCC have any type-acceptance requirements that
this sort of consumer receiver has to meet which would include that
specification? Or could I try to market a set which tuned, say, 500 - 1000 kHz
only, if I were that dumb...? :-)
