Grundig Satellit 500

Formerly Grundig's flagship portable SW receiver, this is still an excellent piece of equipment.  Excellent sensitivity and selectivity.  Digital display with two separate clocks (only one displayed at a time), signal strength meter, frequency readout, and four-character user-definable "name" for each memorized station. 42 memory positions. Tunes to .1 kHz increments. Selectable wide/narrow bandwidth for AM mode reception. Tunes MW in 9 or 10 kHz steps. Keypad frequency entry. In addition to AM, has three receiving "modes" for LW, MW, and SW: USB, LSB, and "Sync," which should more accurately be described as "fine tuning," as this implementation of synchronous detection operates differently from the Satellit 700 or Sony 2010.  Selectable automatic/manual gain control.  Covers LW (150-353 kHz), MW (528-1611 kHz), SW (1612-30000 kHz), and FM
(87.5-108 MHz). Excellent audio output,  with separate treble and bass controls.  Stereo through headphones.  Line-level out (mono), external  antenna, and 12 VDC-in jacks.  Local/DX switch. 
Built extremely rugged.  Power supply included. An all-around great performer.

Price was $379 from Universal Radio in December.

User's report ,as found on internet:
I have a Grundig Satellit 500 and am basically satisfied with it. I miss the 512 memories of 700 and 'SSB clarify' control sometimes.

Yes, its 'sync' is exactly fine tuning in 100 Hz steps. However, it is rather simple to make it work similarly to '700 and '2010, because the detector chip is the same in all three. Only a switch with two pairs of contacts is needed. Another design fault, the excessive distortion in SSB mode, can be partly cured by adding two resistors. For serious DX-ers it may be important that the internal ferrite rod cannot be disabled on MW and LW in both 500
and 700, so the in-house noise may become a problem on these bands.
