Nordmende's Galaxy Mesa 7000 is a portable shortwave receiver covering all popular shortwave broadcast bands. With it's 47 x 26 x 11,5 cm and a weight of 5,5 kg, it is a huge and quite heavy set. It favourable resides on the desk in a home then in a bicycle bag when You plan to go camping...

All important controls are found on the front panel, only the battery and mains wire compartments are located at the rear. The two telescopic antennas are located at the top of the set, at both sides of the carrying handle.
The speaker grill is located at the left of the frontpanel, the big panel with all dials in the middle. in a similar way as found in the slightly older Globemanager, the wavebands are switched by the big pushbuttons next to the corresponding frequency dials.
At the right, just below the S-meter which can be set to display signal strength or battery strength, You find the tuning knob for long- and mediumwaves and the tropical band marked "SW" / "K".
The center part of the middle tuning knob "BANDS" sets the turret tuner for the different shortwave broadcast bands, to tune to the correct frequency, use the outer part of this knob. The bandspread dials have coarse frequency marks helping You to find the correct frequency, the selected band segment is indicated by a red arrow in the dial pointing to the corresponding frequency band indicator just above the band spread window.
The tuning knob underneath tunes in the FM / VHF broadcast band.
In the bottom row of controls, You find from the left the On/Off switch, three slide controls for volume, bass and treble and pushbuttons for battery strength indication, P.U. / amplifier mode, dial illumination and the third knob switches the AFC in FM mode and the narrow and wide AM filters.

The Nordmende Galaxy Mesa 7000 is not difficult to operate: Pull the antennas out, turn the set on. Set to shortwave broadcast bands with the pushbutton BANDS and use the turret tuner to select the 49 m shortwave band, the red triangle will point to the 49 m band mark, and look out for the strong signal of Deutsche Welle, Cologne, somewhere between the 6.05 and 6.1 MHz frequency marks.
As with other worldband radios from the same age, many sets have contact problems within the turret tuner arrangement, the bandswitch pushbuttons, and the slide controls for volume. Cleaning using a soft tuner spray may help, do not use intense solvents that might ruin the resistance track in the potentiometer and be careful not to break or loose the knobs of the slide controls (quite often, they are lacking)

In summary, the Nordmende Galaxy Mesa 7000 is an impressive multiband shortwave radio giving You acceptable performance on the shortwave broadcast bands, You can catch many Foreign Services of the major broadcasters. The set is not suited as a real DX receiver, it's filters are quite broad, suppression of unwanted signals (mirrors) is poor due to the single conversion design, the set does not receive CW and single sideband transmissions from radioamateurs as it comes without a BFO and of course, it is not stable enough for radioteletype reception. The Galaxy Mesa is a collector's radio, DXers should look a around fo a set with an exact digital frequency display and SSB capabilities.
