It was not before 1984 when Yaesu entered the market with it's FRG-8800, the first microprocessor controlled PLL synthesized all wave receiver. This receiver has some advantages over the sturdy FRG-7700, but also some disadvantages.

The FRG - 8800 has a significantly modernized appearence with it's dark grey metal cabinet and the large LCD display; it's dimensions are 33.4 x 11.8 x 22.5 cm, it's weight 6.1 kg very similar to its predecessor.
The radio is intended for mains operation, the voltage can can be selected between 100 - 240 Volts, car battery operation is only possible with an optional car battery adaptor. Always remember to insert three AA cells before turning on the receiver, otherwise the receiver behaves like the Philips D-2999: You will only hear a constant beeping noise. The batteries are needed for the preservation of the memory content and clock time.

The speaker is located on the left side of the front panel, below, You find the power switch and the jacks for headphones and tape output. At the right of them, You find the squelch control, the tone and the volume control AF GAIN. At the left of the main tuning knob, You find the reception modes pushbuttons, below tiny switches to select the narrow and the wide I.F. bandwidth, the AGC speed and the noise blanker.
The main tuning knob is easy to use, the tuning speed is selectable from slow and fast. An additional knob acts as fine tuning control.
The green backlit LCD display indicates the reception frequency with a resolution of 100 Hz, the signal strength indicator is an electronic bar indicator.
At the right of the front panel, there are the controls for quartz clock with two time zones, the timer functions, below the numeric keypad for direct frequency input. Entering a reception frequency is something You have to get used to: Enter first the MHz digits of the desired frequency and confirm with the MHz button, then add the kHz digits of the frequency followed by the kHz - button.
Some more keys are used to deal with the memory and VFO management (slightly complicated with the Yaesu set: like in amateur radio transceivers, the radio uses the VFO concept: the active frequency is stored in the (virtual) VFO and can be sent to a memory are recalled from a memory into the VFO.
In the bottom row of controls, You find the rotary selector for the twelve frequency memory channels (the FRG-8800 has not more memories then it's predecessor) and the RF Gain control.

The FRG-8800 is a good performer and can still be used for uncomplicated DXing nowadays, once You have got used to it's operation scheme...
